Efficient Sulfide Ore Flotation Separation

2018-10-05 Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility and the useful minerals and gangue minerals are usually of similar types with a small difference in surface properties.

Copper-nickel sulfide ore flotation process

Flotation of sulfide ores is known the use of different reagents - collectors. The most common are sulfhydryl - xanthates especially butyl dithiophosphate and combinations thereof. Xanthates are very efficient collectors of all sulfide minerals. Dithiophosphate have sufficient selectivity of action but have less collective ability 1 2.
