The work presents the results of studying ash and slag disposal areas of Primorsky Krai energy enterprises-the objects with high concentrations of Au and Ag. The chemical and mineral contents of samples from the investigated ash and slag disposal areas have been determined. It is shown that the found particles of free gold and of other noble metals are mostly represented by fi ne and ultrafi ne sizes. It is also shown that morphology diversity is typical of gold microparticles. The patt erns of Au collection and allocation during the working process in ash and slag waste (ASW) were found. The possibility of using the materials obtained during the separation of ASW as materials for diff erent industries is shown. An appropriate, multistage way of complex ASW recycling has been developed. The possibility of creating a profi table plant for complex processing of ASW is shown. It is also shown that additional extraction of useful components from concentrates of gold and platinum group metals (PGM) can signifi cantly reduce the payback period of production on complex processing of ASW. KEY WORDS: technogenic deposits of gold, wastes of energy enterprises, ash and slag, complex recycling of mineral raw materials, fi ne-dispersed gold, iron-bearing concentrate, coal underburning

The research results of technogenic objects in the Far East of Russia, in particular, the silt of the settling pond "Chalgany" and the waste of the Chalganov kaolin plant are given. The presence of valuable components in the investigated objects is shown, in particular: gold, noble metals, rare earth elements. It is established that gold in the investigated objects is represented mainly by a difficult-to-extract finely dispersed class of fineness (<5 μm). The methods of preliminary concentration and hydrometallurgical processing, which allow extracting gold from the studied technogenic objects, are proposed. The effectiveness of noncyanide methods of ammonia-thiosulphate and thiocarbamide leaching was investigated. It is shown, that the efficiency of gold recovery from the silt of the settling pond “Chalgany” by the thiocarbamide method reaches 93.5%. It is established that the waste from the Chalganovskiy kaolin plant, after recovering the concentrate of precious metals from them, can serve as a raw material for the production of chemically pure silicon and silica, as well as aluminum, its compounds, and refractory fibrous materials.
