PROCESS FOR RECOVERING MINERALS AND COMPOSITIONS FOR USE IN THIS

摘要

The invention provides a process of separating minerals from a mineral-containing material by froth flotation comprising forming an aqueous pulp of particles of the mineral-containing material, subjecting the pulp to flotation in the presence of one or more dialkyl thionocarbamate collectors, allowing preferential separation of the particles in the pulp to occur to form Reject and Accept fractions and separating the Reject and Accept fractions. In this process dialkyl thionocarbamate collector is added to the mineral-containing material or pulp in the form of an oil-in-water emulsion comprising dialkyl thionocarbamate collector in an amount of 5 to 95 wt.%, emulsifier in an amount of 1 to 30 wt.% and water in an amount of 5 to 95 wt.%. The dialkyl thionocarbamate emulsion is also a novel product.
