Processing Nickel Ores - Mine Engineer
The ore is then ground to -100 mesh in ball mills. Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to -200 mesh in a ball mill. Classification is accomplished with screens and cyclones. The pyrrhotite is then sent to froth flotation cells, and produces a 3% nickel concentrate.Read More
