enrichment, nickel ore is more silicon, more magnesium, lesser iron, higher nickel, and lower cobalt, which is called magnesium garnierite laterite ore. Both ores, relative to nickel sulfide deposits, are called nickel oxide ores [4–6]. Laterite nickel ore is the most abundant nickel ore resource in the world. The nickel in laterite
In recent years, extraction of zinc from low-grade mining tailings of oxidized zinc has been a matter of discussion. This is a material which can be processed by flotation and acid-leaching methods. Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process.
Mexican copper ore is a mixed ore containing mainly copper oxide and some copper sulfide that responds well to flotation. The joint techniques of flotation and leaching were studied.
