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. Special dry beneficiation methods: Magnetic separation of ore

Electrical separation of ore

Ore separation by color

Ore separation by shine

Ore separation by hardness

Ore separation by form

Ore separation by friction

Ore separation by elasticity

Ore separation by size (with selective crushing and grinding)

Ore separation by density (in air)

Separation of ores by ability to adhere to body surfaces (or other surfaces)

Separation of ores by ability of the mineral to obtain triboelectric charge through friction

Separation of ores by ability of mineral to crumble when heated (decriptation)

Separation of ores by ability of mineral to crumble when frozen

Separation of ore by reflectivity of mineral when using various types of physical radiations (optical methods, photometric separation, radiometric sorting, fluorescent separation)
