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.

Abstract: An air concentrator for dry separation of gold and other heavy minerals from alluvial deposits comprises a housing (50) having a number of open-topped chambers (52) arranged in a ring-like configuration and surmounted by a screen (14) having rings (39, 41) thereon forming annular screen beds (36). A wiper bar assembly consisting of a number of wiper arms (6, 7) radiating from a hub (1, 2) sweeps over the screen beds (36). Air under pressure is fed sequentially and cyclically to the chambers (52) by a rotary valve (28) located centrally of the ring of chambers. The deposit is fed over the hub (1, 2) and is swept outwardly over the beds (36) on the screen (14) by the wiper arms (6, 7), where it is fluidised by pulses of air from the subjacent chambers (52) enabling particles of gold and heavy minerals to settle down to the bottom of the beds (36) by gravitational stratification, and if sufficiently small, pass through the screen (14) for collection through spigots (38) in the bottom of the chambers (52).

Abstract: Gold ore, or any other mineral treated to have a lyophilic surface, (e.g. chalcopyrites), is ground into a slurry in crusher (1), powdered coal and oil are added at location (2), and the mix is conveyed to a contact zone (3), where any micro-agglomerates formed are kept below 500 microns in size. Sequentially, the mix is passed to an agglomeration zone (4), where larger agglomerates of coal-oil and gold or the lyophilic mineral are allowed to form, then separated at (5) from the gangue (8), and recycled continuously via return line (6) and homogeniser (7) to the contact zone (3), until a desired gold or mineral concentration in the agglomerates is achieved. Subsequently, the "loaded" coal-oil agglomerates are tapped off the return line (6) at (9), either batchwise or continuously, and the metal values are recovered by pyrometallurgical or conventional separation techniques.
