FROTH FLOTATION RECENT TRENDS Flotation of

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for

Enhanced methods for nickel recovery from lowgrade ores

Enhanced methods for nickel recovery from lowgrade ores

The second stage of froth flotation produces a nickel concentrate of 10-20 Ni, along with other by-products and gangue. Smelting is the next stage, designed to recover as much metal as possible. Flash smelting is a common method dry concentrates are fed into a furnace and heated to a liquid matte and slag. From this step, sulfide matte can be ...
