Abstract:
The invention relates to low-waste hydrometallurgy of precious metals, in particular to a method for refining precious metals and can be used for increasing the ratio of extraction of precious metals from alloys and to improve the purity thereof. The aim of the invention is to develop a method for refining precious metal-containing material in such a way that precious metals are extracted in a most complete manner and with a high-purity degree. The inventive method for refining precious metals consists in saturating a melt by means of a gas composition which consists of at least two gas components and is used for forming compounds with main metal impurities at a permanent superhigh pressure, in adsorbing saturation products in vacuum and in filtering said saturation products in vacuum by means of a filter, the heat temperature of which is greater than the temperature of the melt.
