The mechanism of action of flotation reagents

 Dear colleagues, specialists, friends.
I propose to discuss an interesting topic. What is the most important thing in the reagent flotation mode? Share your opinion! We will all be very interested to know what is the main thing at your plant? What do you pay the most attention to? Have a nice chat!

The mechanism of action of flotation reagents and the intended effect depends on:
1. Type of flotation reagents, dosage and order of addition.
2. Method of preparation of flotation reagents.
3. Use independently or as a mixture with other flotation reagents.
4. Conditioning time of the flotation reagents with the pulp.
5. Addition points for flotation reagents.
6. Type of minerals and particle size.
7. Presence in the mineral of fine, ultrafine particles, clays.
8. Hardness of water and type of machinery.
9. Circuit configuration and circulating load.
10. Conditioning time.

What minerals did you find?

 The USGS names the following critical minerals: " barite, fluorite, graphite". USGS believes that helium gas is also a mineral.

THE EUROPEAN COMMISSION names the following critical minerals: "Coking coal, feldspar, fluorspar, natural graphite, talc".

ESRC Centre for Climate Change Economics and Policy, Grantham Research Institute on Climate Change and the Environment, London School of Economics and Political Science, University of Leeds names the following critical minerals: "coking coal, barite, bentonite, feldspar, fluorspar, gypsum, magnesite, natural graphite, talc".

The World Bank and ICMM did not find critical minerals

In fact, each of my classifications is a "Petrovsky's Matrix"

In fact, each of my classifications is a "Petrovsky's Matrix"- They are very easy to program.
For example, flotation machines of this type can be interchanged with each other.
Ferced aeration mechanical flotation machines are flotation machines, in which pulp aeration is done by compressed air consumption, but dispersion of air and pulp mixture is made by a rotating rotor.
   DOOR-OLIVER cells (FLSmidth, USA)
   BQR (South Africa)
   RCS (Metso, Finland)
   Denver DR (Made in USA)
   AGITAIR (USA)
   BCS (Minemet, France)
   Humboldt Wedag (Germany)
   RIVS (Russia)
   IZ (Poland)
   AKER (Norway)
   Outotec, Outokumpu (Finland)

 Supercell flotation machines
In concentrator plants where the minerals are treated with low-grade and high capacity flotation machines of high volume (5000-240000 tpd). Flotation cells up to 600 m3 making more use of trademarks:
   SuperCellTM (FLSmidth, USA)
   RCS flotation cells (Metso, Finland)
What flotation machines do you have in your plant?

What flotation machines do you have in your plant?

Flotation machines of this type can be interchanged with each other.
Self-aerated mechanical flotation machines, subareation cell, self-aerating machines, self-aerating cell, self-aerating tanks, self-aerated cell, sub-aerated cell, self aspirated cell
Self-aerated mechanical flotation machines are flotation machines, in which aeration and pulp mixture is done by a rotating rotor.
To self machines belong cells brands:
WEMCO (FLSmidth; USA)
Celda DENVER Sub-A. (USA).
Gumbold (Germany)

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

Mountain education is for the poor

 Young people do not understand anything in the future. I did not listen to my dad, who told me to go to study at the oil university, and not at the mining one, I regret it all my life.
Your mining education is worth nothing. You have no equipment, no practitioners, nothing. Let them study to become an economist or a lawyer. More money will be made. Mountain education is for the poor.
WILL DIPLOMAS AND CERTIFICATES HELP YOU BECOME A BILLIONAIRE IN MINING AND METALLURGY? YES, IF IT IS DIPLOMAS OF ECONOMICS, MANAGEMENT, BUSINESS!
