Gladiolus: Top 10 posts for half a year

1. For me, it's not news that the USGS does not distinguish minerals from metals. Why didn't anyone tell them about that for 100 years?

2. THEY HACKED MY ACCOUNTS AGAIN

3. If I use XRF to the golf course, possibly I will find more than 30 chemical elements. What do you think, can this golf course be a mineral deposit?

4. The Chinese company XINHAI has created a website on my behalf. The site contains advertising of state company of Chile "CODELCO". I DID NOT GIVE PERMISSION TO USE MY NAME!

5. WHY GOLD IS NOT A CRITICAL METAL AND A STRATEGIC METAL?

6. One geologist told me: "I've found a deposit of REE"

7. They in Centre for Climate Change Economics and Policy and Grantham Research Institute on Climate Change and the Environment don't know the difference between minerals, metals, rocks, mineral groups, metal groups and so on

8. THE SEARCH

9. They (Camborne School of Mines, University of Exeter, University of London, UK) do not know what apatite, thorite, fluorite, brockite occurrence are unpromising for the production of REE

10. I'm not interested in working in an university group or other scientific group or a team

To whom will you sell iron concentrate with a high content of silicates?

Erik Ronald wrote "The Curious Case of Metal Bias": "That said, I was in Chile recently looking at some IOCG deposits and was surprised to find a company operating several IOCG’s focused solely on copper. Nothing against copper of course; but when your deposit hosts an average Fe grade of 40 % and consistently runs between 0.25-0.4 g/t Au and 2 g/t Ag a company should likely aim to maximize what Mother Nature provided."

First, they write that they have 20-25% iron in the ore. 

Consider an example.

After magnetic separation, La Planta Magnetita has the obtained iron concentrate with an iron content of 70 %. It's good.

The concentrate comprises 1.87 % of SiO₂ and 0.52 % of Al₂O₃. This is very bad. These are harmful impurities. In fact, the content of silicates will be much greater than in laboratory experiments.

China refused to buy this concentrate with a high content of silicates.

In reality, the problem of removal of silicates and aluminosilicates from iron concentrate has not been solved so far. 
Who will buy this concentrate from you? 

They write that they can remove silicates by reverse flotation. It's half true.

The flotation has a problem. When adding a starch to the the flotation, the content of SiO₂ in of iron concentrate is 0.8-0.9 %.

If carried out flotation without the starch then content of SiO₂  in the iron concentrate is 0.8-0.9%. 

Obviously, there is no effect from the use of starch. 

What happened? Why in both cases the content of SiO₂  in the iron concentrate equally high and much higher than the required?

Will they be able to solve this problem?

Which occurrence (field) will you choose? Why?

There are two occurrences of iron.
The first occurrence contains 16 % of iron.
The second occurrence contains 40 % of iron.

WHY GOLD IS NOT A CRITICAL METAL AND A STRATEGIC METAL?

Why do countries have a "Strategic gold reserve", 
but gold is a "Non-strategic metal"? 
Paradox?

Operate unconventionally! Do everything yourself!

Really the life separates everything into rich and poor: states, cities, people, languages, forests, seas and ores. But this order of things is very conditional and dynamical. Everything flows and changes. A poor city turns into glittering megalopolis, a deluxe company goes bankrupt and pauper people get rich. Like any poor ore can be converted into a rich concentrate, and an average person can get a fabulous capital. We know many examples of this.


But how to do it in the mining sector, for example?

We'll give you a frank answer: If you go the traditional way and you involve intermediaries, any money will leave as water in the sand without result. They will offer you a standard solution to build a plant and another plant. This is the standard approach and ineffective.

Our theory of enrichment consists in the following. 

The success or failure of the case is laid more on the level of ideas. Line up and solve the problem theoretically in the head, to simulate the situation before an investment - is to make 80 % of case. The rest is a technical matter. Our strong point and our trump card is a possibility to choose  theoretically the optimal processing technology for any ore. We'll help you get rich!

Operate unconventionally! Do everything yourself!

For big profits you need rare solutions, you need people who know the minerals, reagents, metals, mineral separation methods ...  Ask the expert to which you applied, how many ways of ore enrichment he knows? 2-5? He will build your future of these options. But can a prospective multimillionaire conclude a deal, having the presence of only 5 options? The answer is simple: “no”! He sees up to 100 variants to choose one!
We know hundreds of mineral separation methods, new modern machinery and reagents worldwide. We are not engaged by certain brands of equipment and reagents. We will offer you all the best in the world that can be found today.

We will help you to avoid unreasonable and useless costs even before a planning stage.

Contact us directly. Don’t buy anything without our independent assessment - this is too risky. Don't succumb to cheap promises and simple solutions. Anything of these doesn't exist. Each step can lead you to great loss. Remember that! We will share with you the knowledge that any expert doesn't have in the world! We know everything in the mineral enrichment. We have no competitors. Only we can theoretically calculate and simulate FOR YOU  the UNIQUE TECHNOLOGY, which anybody doesn't have in the world.
Hurry, because our small team may be busy again on another project, and you will have to wait.

Give yourself a chance to become rich and to earn a billion!
Read in the second part of the article specific examples of how to get rich.

MINING MONEYBALL

Small investments can guarantee big profits
 
I liked the film "Moneyball". The baseball club was in a difficult situation, the best players left, and the club's funding is 2.5-5 times less than that of other clubs. How to achieve victory?

Analytical calculation versus the collective wisdom
 
In the film "Moneyball" there is an episode when the scouts and the manager choose new players for the club. Look at the criteria they operate on. Like - not like, good - bad, there is a recommendation - there is no. Scouts are clearly subjective. They try to use their wisdom and intuition.
The manager of the club contrasted the accurate analytical calculation to the collective wisdom. He developed a new strategy for selecting players based on a mathematical modeling. As a result, his team went into the playoffs at a cost of 5 times lower than that of other clubs.

The mathematical analysis have their own special beauty, but it is not open to everyone
 
Our "philosophy of beneficiation" is based on rigorous mathematical analysis plus our knowledge and experience.

We count all the steps before spending money. The result is guaranteed.

If your mining team is at a similar situation, then we can help you get into the playoffs of the world league at low cost. No guesswork - only a rigorous science!
 
You must be ready to give up stereotypes to win.

I can't trust this report of the World Bank and ICMM

The World Bank, in collaboration with the International Council on Mining and Metals (ICMM, London) wrote a report "The Growing Role of Minerals and Metals for a Low Carbon Future"

Authors are Arrobas, Daniele La Porta; Hund, Kirsten Lori; Mccormick, Michael Stephen; Ningthoujam, Jagabanta; Drexhage, John Richard.

The name and essence of the report do not correspond.
For example, they want "... Metals for a Low Carbon Future".
I'm reading a Wikipedia "Steel is an alloy of iron and other elements, primarily CARBON."

For example, they do not understand that bauxite is aluminum ore, not metal.

Steel is not a metal and is not mineral - it's an alloy.

Cadmium and molybdenum are not rare earth metals.

Lithium is not a base metal.

Molybdenum and indium are not rare-earth metals.

Iron ore is not a metal.

Silicon is not a metal.

The title of the paragraph "Global Distribution of Reserves and Production Levels of Key Metals Critical to a Clean Energy Future". They write about silicon. Silicon is not a metal.

How do you think? Do bankers need to know billionaires of Forbes? Probably they should know. This is their direct work.This report proves that they do not know billionaires of Forbes.

I can not trust this report

They do not understand in metals. They do not understand in minerals.
Other specialists have already begun to rewrite these errors.
This is very bad. They made many gross mistakes.

You can not use Eurasia's technologies in the Americas?

One asked me: "Can I use Eurasia's technologies in the Americas?"

I answered: "I think that this is a bad idea.
I found that the kinetics of flotation of ores in Eurasia has the appearance of an exponent or sigmoid, but the kinetics of flotation of ores in the Americas has the form of a "false exponent". "

"False exponent" is a new concept that I introduced.
