Progressive flotation machines and auxiliary equipment of the world

 Dear Colleagues!
I am writing a book “Progressive flotation machines and auxiliary equipment of the world”. This information will be used to create algorithms and programs within the “Mineral Benefication Information System” for the selection and calculation of equipment for flotation. I need information about your equipment and your services.

I create “Mineral Benefication Information System” by the following criteria:
1. The design and principle of operation of the flotation machine
2. What physical processes occur in the flotation machine of this type.
3. Types of aeration used in this machine
4. For which types of flotation, you can use a flotation machine of this type. Expansion of the scope of activities.
5. Improving flotation control
6. Advantages
7. Disadvantages
8. Prospects for modernization and improvement
9. Recommended reagent modes and schemes
10. Methods for calculating flotation machines
11. Other.
This data does not exist anywhere. I will analyze every machine myself. Often, manufacturers of flotation machines themselves do not know all the advantages of their machines, which limits the scope of their use.
Feel free to offer me everything you have not only for flotation, but also other equipment for the separation of minerals.

Which lineup of flotation machines do you prefer?

 Friends and colleagues. I really enjoy our discussions. Which lineup of flotation machines do you prefer (equipment layout)? 1 or 2? Why?

 #1. 

We use one pump for the entire chain of flotation cells.

#2
а) We use one pump per flotation cell for large volume. If the volume of the cell is small, then we use one pump for 2, 4 cell.4 machines in the
b) You can alternately use, following order 1 - Self-aerated mechanical flotation machines and 3 Ferced aeration mechanical flotation machines.
c) You can install all Self-aerated mechanical flotation machines.

I found only one company that has cells of both types - this is the (FLSmidth, EE.UU.).
The rest of the companies will install their cells according to the first type. This is a forced necessity.

Tell us how you repair equipment? What crane do you use?

 Dear Colleagues, Experts and Friends
We calculate the approximate height of the building in this way. The whole building needs to be heated in the winter. The height of the building depends on the overhead crane. You need to lift the largest equipment. There should be a clearance of 0.5 meters. Plus the roof.
In Chile, Peru, USA, Mexico they don't build buildings, they don't heat them.

What is innovation for you?

 For everyone, the concept of "innovation" has its own meaning. What is innovation for you?
1. Technologies of copper-porphyry ore processing have been used for over 100 years, but they are "Innovative technologies" for Russian Copper Company?  They could not solve the problem of silicates for 100 years. Now this is your problem too.
2. They wrote on the site «The National University of Science and Technology "MISiS" (formerly Moscow Institute of Steel and Alloys State Technological University»:
 «Innovative technology of smelting cast iron»
Can we read that technology is innovative, if she could not break into the market for 40 years?
I think not.
They say they can get a slag of a certain quality (Slag is a waste of pig iron production).
Why should I slag? I buy a stove to get cast iron.

 I will now write many formulas, and you will not even understand. And specialists from Switzerland and Germany will say that this is very good. You see just a gallery in Chile (canaletas abiertas), but I see an innovation that has been dreamed of in Russia for 50 years, they don't even know about it.

Yes, in America they don’t know theory well, but practice always outstrips

 Imagine the gulf between Russia and America. In Russia, they dream of creating at least a small combined flotation-gravity unit in order to go down in history. They even gave drawings to China, just to make it., just to make it. And in Chile they have a gigantic industrial combined flotation-gravity installation and do not even understand how lucky they are, what a miracle they have.
And the Russians are still messing around in the laboratory, creating what Chile already has, only much better.
It was exactly the same 100 years ago with the agglomeration plant.
Yes, in America they don’t know theory well, but practice always outstrips.

Natural floatability

This topic of "natural floatability" was studied by my colleagues in Russia 50-60 years ago, including me. It has not taken root anywhere and has not been used.

For example, talc has a natural floatability, and it is almost impossible to achieve anything. Therefore, they simply find good deposits and grind it up for enrichment.

Molybdenite is one of the few sulphides with natural floatability, but why is its recovery less than 35%?

Quartz is the most hydrophilic mineral, but if crushed too much, it will float on the surface of the water. 

How can you explain this? I did a lot of calculations, I have the answer to these questions.

I think that the future lies in the processing of porphyry ores

 I think that the future lies in the processing of porphyry ores. This is the most promising direction for the development of reagents or the development of other separation methods. Flotation is a very good direction too, but we need a large range of reagents. What do you think about this issue?

  I think we need a very wide range of reagents. Chemical companies must produce reagents for porphyry ores. I have seen 50 year old patents from some well known reagent manufacturers on the internet. I liked them. They exist. The experts tried. So give us those reagents. We really need them. It's time to get on the right track.

38. #323 Simon Reuben (United Kingdom) - aluminum, steel, copper
In 1997, Russia's Interior Minister Anatoly Kulikov linked both the Cherney brothers and Reuben brothers to the Izmaylovskaya mafia led by Anton Malevsky in Israel. In March 1998, Boris Yeltsin replaced Kulikov as minister.
In the early 1990s, the brothers invested in the Russian metals market. When Russian aluminum smelters were incapacitated by debt, Reuben company Trans World entered into tolling arrangements with factories in which they paid for and delivered raw materials in return for finished aluminum, which it then sold for profit.[9] The company's investment in Russia was US$1.5 billion (£870 million), with global sales in 1995 above US$8 billion.

It's all about tradition

 Let me explain the situation to you.
IMHO, It's all about tradition.
Who in America runs the businesses? Managers, economists and lawyers. They don't care what they manage. For example, John Sculley doesn't care what he manages, Coca Cola or Apple. He managed to fire company founder Steve Jobs!
In Russia, enterprises are traditionally run by specialists. That is, mining enterprises are managed by professional miners, metallurgical enterprises by metallurgists, chemical enterprises by chemists, and so on.
Therefore, with a small number of universities in the ranking, the number of billionaires is much larger.

This is all a marketing slyness for naive investors and shareholders

In the ore processing, there are no "new", "newest" and "innovative" technologies for processing minerals today.  All currently used ore processing technologies have been well known for decades of years and hundreds.

Therefore, everything that is presented today by marketers as an "innovative cherry on the cake" is just a modernization and a combination of the well-known.

For example, they cut and roughly compile two or more well-known technologies, simply mechanically combine them, and offer this to investors under the guise of "innovative science-intensive products."

I answered: "As far as I know, other kind of mills are traditionally used in the processing of sulfide ores. SAG mills are used in the processing of porphyry ores.
It's not entirely clear to me, where what is the novelty of the technology here? Maybe only a new Leadership?

The mining industry has long been in need of something significantly newer which will then be used for another 100 years or more. This is what I see as the main goal of my scientific activities and social and i do it on my own

Probably, I will not reveal a big secret if I tell the respected public such an inconvenient truth: In the mining, there are no "new", "newest" and "innovative" technologies for processing minerals today. This is all a marketing slyness for naive investors and shareholders.

 
All currently used ore processing technologies have been well known for decades of years and hundreds. Therefore, everything that is presented today by marketers as an "innovative cherry on the cake" is just a modernization and a combination of the well-known. For example, they cut and roughly compile two or more well-known technologies, simply mechanically combine them, and offer this to investors under the guise of "innovative science-intensive products." After all, "it has not exist before."

And all this is not done to improve production efficiency. Not at all! Production efficiency may even decrease. Nobody really cares about it. Their main task is to sell the same thing, but at a significantly higher price under an "innovative" sauce. I believe that old stuff should be worth the same old price.

As for me, the existing technologies for processing minerals have long been exhausted. Ores are becoming poorer, ores of complex composition are involved in processing, outdated processing methods, ineffective reagents are used. No matter how you modernize old technologies, it will not become new. All of this would have been great 100 years ago, but not now.

The mining industry has long been in need of something significantly newer, really new processing technologies, which will then be used for another 100 years or more. This is what I see as the main goal of my scientific activities and social and I do it on my own.

I'm not interested in deceiving people and selling  old stuff to them at exorbitant prices.

ABOUT INVESTMENTS by Natalia Petrovskaya

Dear friends.
You offer me to develop a business in my country.
But, what country are we talking about? What does “my country” mean?
I am a man of the world, cosmopolitan. I am out of politics. I feel myself so. For me, all countries are mine.

See my diagram. Criteria of Petrovskaya: metals – minerals – deposits – technologies. Where is no the country, the state.

I look and choose only minerals and deposits. But not  countries. I can choose the best deposit, equipment, reagents, create  technology and get profit.
As for the political system, stability, etc., you decide which country is best for you business, I am not a politician.

As a person who is responsible and honest, I can tell you  frankly that I will not vouch for anyone (person, team, enterprise …).  I  am confident only in myself.

Therefore, if we are talking about relatively small investments (about USD 10-20 millions), then I can recommend you to invest in me, this is the most reliable investment.

So, my business plan is an investment in me and under my name. Then  we decide what is best for you, we can determine in detail the larger  investments (under USD 1 billion and more): where and how to do it  better. To determine this, I need to work hard and count.

No one (except the scammer) can tell you reliably on the fly: “Now this is the right thing to do! Invest only there!”

All the available information about the object, calculations and experience are needed to say this.
Hurry up, because I may be busy in another project very soon.
Respectfully,

Ph.D. Natalia Petrovskaya, 2018

GOODBYE, UNIVERSITIES!

You often ask me: "Why do not you want to work in an academic environment at the university of some country?"

I answer: "It's true. I really do not want this. I do not want to participate in Lie! Therefore, I do not want to work in an academic environment.
I'm an independent scientist!"

I do not take judging about the scope of scientific knowledge from which I am far. However, what they (academic science) write in their articles about my whole area of the mineral processing, this is a complete nightmare and ignorance. I read the articles in different languages and I am horrified. These "scientists" do not even understand what they write. Most of them simply rewrite other mistakes and misconceptions. This is not science. If there are guides, then the processing of minerals is in a steep peak. The poor Earth Climate will not take away this ignorance. 
 This is not my way.

Academic community seeks to score each scientist a label of the country, scientific school or university: "If a scientist  reached any scientific heights, this is not his merit, but it means that his country (which of them?) is such a "great" and "wise" (scientific school or university too). This is not discussed! In their opinion, the personal merit of the scientist does not exist without THE MERIT OF THE UNIVERSITY. So the delegations go to establish academic exchanges. Agreements on intent are signed. They appoint official "teachers" and "disciples" of this scientific genius, so that these official "teachers" and "disciples" sign any fraudulent contracts and projects without reading. The lie is multiplied.
But I do not want to participate in this lie! 

I do not have any teachers or disciples! I was taught only on basics of sciences as well as thousands of others students. I reached my wisdom by self-knowledge! And I did not give to anyone the depth of my knowledge, I did not teach anyone. Everyone who calls himself as my disciple (or teacher) - is the IMPOSTER.

We are cosmopolitans!  

We work for all of humanity, not for a country or a university. We are working independently for many years.   We are in us self. Do not associate us with some country, scientific school or university!

They do not own our knowledge; they do not have the authorship in our inventions and our know-how. Several countries and universities try to attribute our merit to its self. But they do not have anything, except their positions and rights of the signature in their  university and their country.
We are not serfs! We do not belong to them as the results of our work too! 


They can not create anything  really working, but only counterfeit and only on paper.

The role of personality in science is strongly underestimated. This is one of the distributed mistakes of our time.

I'm reading the academic scientific articles, I see that they contain a huge number of errors and deception. I do the comments, but they persistently rewrite the lie from each other and a lie is multiplying.
I feel myself as "Gelsomino in the country of liars".

We try to follow principles of  Real Scientist, one of which is NOT TO PARTICIPATE IN THE LIE. 

I do not want to participate in Lie! Therefore, I do not want to work in an academic environment.
I'm an independent scientist!

You feel a pity for to stop it all, because you have already given the contractor a lot of money

   Excerpt from the article "TEN  SIGNS  OF  A  SWINDLE"

Assume that you are an owner or a manager of mining and metallurgical Plant, and you have a need to solve some complex technical problem (to develop a project of a new Plant, a new technology, to optimize the processes, to change the equipment, software, etc.). You can't do it yourself, because you don't have experts. By an advice of friends you are accessing to the mediation company offering engineering services and much other. "They will help me for sure here! It's all so serious, it's almost a ministry!" Maybe so. But you should not relax. After all, only you are interested in a solution of your problem. All others are only interested in your money and no one is going to save your money. That's for sure!

However, enough the presence of the following features to recognize an unscrupulous contractor: 

Bubble. Under various pretexts, Contractor is actively trying to attract to the implementation of the project as much as possible quantity of performers and subcontractors (often from different countries).
He also clearly justifies the need to divide the project into numerous intermediate parts and sub-parts. Contractor justifies the need for a large quantity of experiments, analysis, tests, consultations.
Why? Indeed, in this case, it is much easier to justify the exaggerated budget of the project and to dilute responsibility for the final result. Who is a culpable, that it didn't work? Immediately one could not tell it. "It's been a part of the project, and it is made with quality! Let's look at a new project, all these things can be improved!"

And your looting continues. 

The worse the work is done, the more contractor earns with additional services to further improve of some things. 

And you feel a pity for to stop it all, 
because you have already given the contractor a lot of money.

The investor asks me: "Help me get back at least some of my investment!" FORGET ABOUT THE MONEY SPENT!

From the series of publications 
"So they create a fairy tales for the investor" - 
"They draw up the necessary documents
and begin to search for the simpleton..."  

The investor asks me: "I bought a mineral deposits. Five years have passed. Many research laboratories in the world have done experiments. No one can get anything. Do at least something! I've already spent a lot of money. Help me return at least part of the money invested."

I always start with a theoretical analysis of the ore. This is my know-how. I am the only specialist in the world who does this. More

I made calculations and told the investor: "Forget about the money spent and this field. Now you have spent millions and have no result.
You can spend another 20 years and spend billions and you won't have results either."

And only that man, who is wise, will come to me today to get advice before investing.  
 
This is your money! You choose!

Barrick Gold has an overrun of US $ 8 billion on The Plant "PASCUA-LAMA" (Chile) that they have not been able to build for 20 years? ? It's true?

From the series of publications 
"So they create a fairy tales for the investor" - 
"They draw up the necessary documents
and begin to search for the simpleton..."   

Plant project "PASCUA-LAMA" (Chile, Argentina)
 
Owners: 100 % Barrick Gold Corp. (Canada)

Barrick Gold has an overrun of US $ 8 billion on The Plant  "PASCUA-LAMA" (Chile)  that they have not been able to build for 20 years? ? It's true?
Barrick Gold plant "PASCUA-LAMA" in Chile has not produced a single ounce of gold or silver for 20 years.


Mark Bristow, CEO said:  "Barrick Gold owes:

• US $ 443 million to the Treasury of Chile, plus $ 340 million in interest.
• US $ 253 million to the Wheaton Precious Metals Corp (amount as of December 31, 2018)

All these obligations are added to the amount Barrick actually disbursed in a project "PASCUA-LAMA" that in its beginnings, almost 20 years ago, cost about US $ 950 million, but which ended with an overrun of over US $ 8 billion."

 Where was the money spent?

 IMHO, The copper and gold content of the ore is very low. It is lower than the outboard content on some mine.
