The monograph presents the results of obtaining and application of surfactants in hydrometallurgical processes of leaching electrolytic cleaning of metals from impurities. It has shown that the initial raw materials for surfactants production can be secondary technical and waste materials of local industrial productions. The modern state and prospects of application of biotechnological processes in processing of refractory ores of non-ferrous and rare metals are considered in detail. Characteristics of surfactants and biomaterials for their industrial application are given. The book can be useful for undergraduate students, masters and specialists in the field of hydrometallurgy of enriched minerals, geology and mineralogy.
