REVIEW: ADSORPTION OF IONS AND MOLECULES TO SOLID .

Valuable sulphide minerals are separated and concentrated from the crude ore by means of flotation. One fundamental step in this process is the selective hydrophobation by a collector of certain sulphide mineral surfaces.

Depressants and dispersants

In mineral flotation the challenge is to maximize the recovery of desired minerals while rejecting unwanted gangue components. Depressants are required to give a low affinity to active sites on valuable mineral surfaces and a high affinity for gangue minerals and some sulfides.

Introduction to Mineral Processing

Introduction to Mineral Processing

In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation.

Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite. Concentrates have therefore been of moderate grade containing as much pyrrhotite as pentlandite or more.
