Dry technology

Dry technology (Dry mining operation)

The dry climate of The Americas creates good preconditions for the use of dry technology. Dry technologies are applied in the pre-separation of the ore in order to allocate more than 20% of tailings in the head of process.
Dry technologies are high performance, efficiency, low consumption of electricity, water, reagents and is very environmentally friendly.

Dry beneficiation methods:

1. Magnetic separation of ore
2. Electrical separation of ore
3. Ore separation by color
4. Ore separation by shine
5. Ore separation by hardness
6. Ore separation by form
7. Ore separation by friction
8. Ore separation by elasticity
9. Ore separation by size (with selective crushing and grinding)
10. Ore separation by density (in air)
11. Separation of ores by ability to adhere to body surfaces (or other surfaces)
12. Separation of ores by ability of the mineral to obtain triboelectric charge through friction
13. Separation of ores by ability of mineral to crumble when heated (decriptation)
14. Separation of ores by ability of mineral to crumble when frozen
15. Separation of ore by reflectivity of mineral when using various types of physical radiations (optical methods, photometric separation, radiometric sorting, fluorescent separation)

The new processing technology with optimal kinetics of flotation!

The technology is designed for the processing of porphyry ores with a high content of silicates (SiO₂). The technology can be used for the flotation of Au, Cu, Fe, Mo, Pb, Zn and other porphyry ores. The process optimization enables to increase a speed of flotation. The proposed technology reduces the number of cleaners, increases a recovery, and improves a performance of the Plant and other indicators. 
The proposed technology is based on my own know-how.
It is easier to prevent problems than to fight them later.
The technology allows preventing the occurrence of major problems in the flotation of minerals or reducing their negative impact.

The advantages of the proposed technology:

• Increasing the recovery of valuable mineral into the concentrate with the same quality concentrate (or improve the quality of concentrate).
• Increasing the speed of flotation.
• Reducing the viscosity of the pulp.
• Reducing the number of cleaners.
• Reduction the number of flotation cells with the same performance of Plant (or increased performance with the same number of cells).
• Savings on chemicals.
• Savings on energy.
• Reducing the load on the equipment, increasing its resources.

Offer for manufacturers of flotation machines

In the world there are a lot of plants for the flotation of this mineral. Flotation is a traditional method of processing of this mineral. Therefore, there are excellent prospects for the use of this solution.Flotation of this mineral is very well studied, but so far there are a lot of problems. The world uses a lot of reagents, technological schemes. However, challenges remain: the low efficiency of the flotation, low recovery.
Advanced studies have shown that the structure, the properties of the crystal lattice of the minerals have unique features (in the same deposit). As a result, the same mineral has different properties in the flotation.
It has allowed me to conclude that one of the most promising solutions is the use of the cells of new design for the flotation of this mineral (for the flotation coarse particles). This machine together with an appropriate combination of reagents will yield a impetuous effect (effect depends on additional reagents too).
Cells of new design can make a breakthrough in the flotation of this mineral. This means that the plant can get a quick profit without significant capital expenses.

The price includes:

1. Flow diagram of the use of the cells of new design  for this mineral. Driving flows and technical justification  (several variants).
2. Several studies of the properties of the mineral and the positive outlook of use cells of new design. Due to its design it is machine can solve the problem for the flotation of this mineral.
3. The theoretical description of processes taking place in the cell.
4. One year of free consultation on this issue.
5. Recommendations for the use of reagents, reagent mixtures to increase the efficiency of the cells of new design.
6. Advertising of cells of new design on my website
