Jan 11, 2016 The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

MoreGraphite ore flotation processing flow chart. Graphite ore can be divided into crystalline graphite, flake graphite and graphite ore with a variety of gangue. The graphite ore beneficiation process is mainly for the graphite ore with different crystal forms, such as graphite ore, pyrite or mica.
MoreIn a flotation process, the ore is crushed and wet ground to obtain a pulp. A frothing agent, usually employed with a collecting agent, is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent flotation steps. The pulp is then aerated to produce a froth at the surface thereof ...
