Minerals Free Full Text Recovery of Residual Silver

As it is possible to have some oxidized minerals in the ZMT tailings, it was important to use sulphidizing agents to recover them. Sulphidization enables the recovery of this type of mineral by flotation. In this study, sodium sulphide (Na 2 S) was used to recover the oxidized sulphide minerals. Before doing so, all of the sulphide minerals ...

Evaluation of Frother Types for Improved Flotation

Froth stability and mobility are important factors that affect flotation recovery and grade. A froth that is too stable may prevent adequate drainage of the entrained material and is difficult to handle while an unstable froth is least desirable due to the negative effect on recovery and selectivity [].The frothers that are more efficient in reducing bubble size have been observed to produce ...

Collector compositions for the froth flotation of mineral

A collector composition useful for the recovery of metal values from metal ores in a froth flotation process comprises two collectors. One collector is an organic compound containing at least 4 carbon atoms and one or more monosulfide units, wherein the carbon atoms to which the sulfur atoms are bound are aliphatic or cycloaliphatic carbons.
