Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore. Feb 01, 2021 Laboratory nanobubble flotation tests were conducted using the setup shown in Fig. 4 to investigate the effect of major individual flotation parameters on flotation performance and evaluate the technical feasibility of reverse nanobubble flotation of hematite samples. The flotation cell is a regular Denver type of mechanical flotation machine ... Jul 13, 2016 Cyanidation of a flotation concentrate made from the raw ore, though it would clean up the exposed values, was a difficult and costly treatment. The development of a cheap and practical method of conditioning the cyanide tails made it feasible to concentrate the values contained in the sulphides and treat them at a profit by roasting.
