Abstract
Process of flotation of minerals, which consists of introducing the flotation collector into the mineral pulp to be treated in the form of a microemulsifiable composition. In general, the collector agents are organic compounds containing sulphur, particularly mercaptans, thioethers or polysulphides, which generally are very slightly soluble in water. This process is particularly suitable for minerals based on oxides and sulphides.
