Flotation machine (also called flotation separator) is widely used for the separation of nonferrous metal, ferrous metal and nonmetal that include copper, lead, zinc, nickel and …
Factors affecting froth floatation Particle Size in Grinding. Both large and tiny ore particles have an impact on flotation efficiency and mineral recovery. Because of their heavy weight, flotation coarse particles are difficult to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.
For some time past the company has been experimenting with a view to finding the best method of concentrating the sulphide ore before smelting. The first test-mill consisted of two sets of rolls, one Chilean mill, one Hardinge conical mill 6 ft. diam. by 12 in. cylinder, Richards hindered-settling classifier, Deister tables, some kind of ...
The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates.
