Introduction to Mineral Processing
Lead/Zinc Ore. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors....

Nickel: Extraction and purification
Apr 24, 2010· In many stainless steel applications, 75% pure nickel can be used without further purification depending on the composition of the impurities. Nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then are smelted. After producing the nickel matte, further processing is done via the SherrittGordon process....
A New Process for Cobalt Nickel Separation
This combination of flotation and smelting effectively removes most of the deleterious impurities, and thus produces a nickelcobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way; however, not all sulphide ores...
