Frothers and gold was recovered by concentrating the gold-bearing sulphides on The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased.
The main focus of this thesis was to better understand the influence of grinding media type on flotation of gold bearing pyrite and cyanide gold leaching in the presence of iron sulfide minerals.
The use of low-quality water in sulphide minerals flotation plants has been studied widely. However, implementation of the strategy of low fresh water consumption and low process-affected water disposal in sulphide flotation requires a comprehensive understanding of the impacts of solution chemistry on sulphide minerals flotation.

In most flotation plants, sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation. Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetra-auricupride [AuCu] relative to native gold.

Selectivity in sulfide flotation arises from the nature of the interaction between collector species and the mineral surface. This takes place by a mixed potential mechanism involving separate electrochemical steps. The process that leads to a hydrophobic mineral surface is an anodic oxidation ...
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 ...
Sulphide flotation of actual oxide copper minerals (such as malachite, azurite) is not possible with sulfhydryl mineral flotation collectors and either other oxide type collectors are required or alternative mineral beneficiation routes must be considered.

The most widely used sulphidizer is sodium sulphide, which is commonly used in the flotation of lead carbonate ores and also slightly tarnished sulphides such as pyrite and galena. In the sulphidization of ores containing precious metals careful control must be exercised as in some instances sodium sulphide has been known to have a depressing ...
