Principles and practice of sulphide mineral flotation ...

This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.

MEI's Barry Wills: Flotation '19 Final Report

2019-12-1  The importance of flotation to the mining industry cannot be overemphasised. In his 1979 article on the evolution of mineral processing, Prof. Alban Lynch, the first director of the JKMRC, felt that it was depressing that that there had been up to that time only three major advances in mineral processing during the century, one occurring in each quarter of the century.

There are several reasons for this - for one thing, such instruments are not readily available, nor are suitable calibration standards. For another, in the UG2 chromitite, the base-metal sulphides themselves occur in trace amounts and as small grains.

Is flotation the unavoidable way for beneficiating

Although it is clear that flotation has become the conventional way for beneficiating metal sulphide ores and will remain so as long as grade is sufficient to bear the cost, other methods have to be taken into consideration. These can be either physical concentration other than flotation or metallurgical processes.
