FINANCIAL CORPORATIONS or MINING CONSULTATION AND SERVICES COMPANIES. Which of them trusts mining and metallurgy more?

 

Which of them trusts mining and metallurgy more?
FINANCIAL CORPORATIONS or MINING CONSULTATION AND SERVICES COMPANIES?

Investment funds, banks, hedge funds, various financial corporations invest in mining and metallurgy plants. Hence, they believe in the future of mining and metallurgy.

Why didn't the consultation and services companies build a mining plant for themselves? It makes sense to build the best plant for yourself. Do they not trust their know-how and innovative technologies?
IMHO, If they don't believe in themselves, then why should we trust them?

“PROGRESSIVE FLOTATION MACHINES AND AUXILIARY EQUIPMENT OF THE WORLD”

 Dear Colleagues! What type do you classify your flotation machines?
I am pleased to inform you that I continue to create the “Mineral Benefication Information System”.

At this stage, I continue to collect information on flotation machines and auxiliary flotation equipment.

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 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.

 

 Mechanical flotation machines:
Self-aerated mechanical flotation machines
Forced aeration mechanical flotation machines
Combined mechanical flotation machines
Special purpose mechanical flotation machines

Pneumatic flotation machines:
Forced aeration pneumatic flotation machines:
Forced aeration pneumatic flotation machines with deep cells
Forced aeration pneumatic flotation machines with shallow cells

Air-lift flotation machines:
Air-lift flotation machines with shallow cells
Air-lift flotation machines with deep cells
Foam separators
Pneumatic flotation machines with porous bottom
Other pneumatic flotation machines (Combined, Special purpose and other)

Jet stream whirl flotation machines:
Jet stream whirl flotation machines with vertical flow
Jet stream whirl flotation machines with vertical flow of high pressure
Jet stream whirl flotation machines with vertical flow of low pressure
Jet stream whirl flotation machines with tangential flow

Dissolved air flotation machines: 
Flotation machines with variable pressure:
Compressor-type flotation machines
Vacuum-type flotation machines
Electric flotation machines 

 Special purpose flotation machines
Vibratory flotation machines
Flotation machines with the action of waves
Other special purpose flotation machines
Combined flotation machines
Laboratory flotation machines 

 

 You also do not know what are "Sustainable Minerals" and what they study at Sustainable Minerals Institute?

 You also do not know what are "Sustainable Minerals" and what they study at Sustainable Minerals Institute? No one knows? Is this classified information?
The billionaire Neal Blue does not hide the fact that he is mining uranium.
Do they study very secretly at the Sustainable Minerals Institute that it is impossible to write in open access?
Vibranium from Wakanda?
Uru from Asgard?
Please list "Sustainable Minerals". What it is? I have asked the workers of the Sustainable Minerals Institute many times, but they don't know what it is.

Express evaluation of technological feasibility of mineral extraction

 Express evaluation of technological feasibility of mineral extraction from the ore deposit for new sites
The evaluation includes the providing to client an electronic conclusion or paper conclusion (on request). In conclusion, are reflected the fundamental possibility (impossibility) of commercial separation of certain valuable components from ore under the current level of ore processing technology, without laboratory experiments and tests.
What do you get in this evaluation?
   You'll know: Is your occurrence a mineral deposit or no.
   You will have an objective view of the ore deposit and of its prospects at the mineral enrichment.
   You'll know what other minerals are possible (or impossible) to extract simultaneously with the main mineral.

The necessary input data for the express evaluation:
   Mineral Analysis from X-Ray Diffraction (XRD), mineral composition of the ore (Required. The apparatus is much better, but not the person)
   The chemical composition of the ore (Required. Can X-ray (XRF). The apparatus is much better, but not the person)
   Description of rocks (It is desirable, but not obligatory)

GAS-GAS INTERFACE EXISTS

 When I wrote my book "Fundamentals of the theory of flotation" in 2007, I was convinced that the gas-gas interfase existed. They proved that I was right.

What are the most important factors?

 For more than 100 years they have written in their articles that the composition of the ore is the only factor that cannot be influenced. I think it's possible. And what do you think?
Do you want to add more technological factors (bubble size, ore inclusions)?
What are the most important factors?
Factors affecting flotation:
1. Ore composition
2. Particle size
3. Reagent system
4. Ionic composition of the pulp
4. Pulp density
5. Kinetics and speed of flotation
6. Aeration and agitation of the pulp
7. Defoaming rate
8. Pulp temperature
9. Optimal pulp flow
10. Fotation types

I think that the production of pellets from xanthate powder is a very big achievement

 Let's have a dispute. How well do flotation experts know the properties of xanthate? I think that the production of pellets from xanthate powder is a very big achievement. Why? Who did it first? When?
