Zusammenfassung:	extraction of gold from production waste of jewelry and other branches of industry. SUBSTANCE: the plant has vessels for reagents and washing solutions connected through pipe-lines to the leaching reactor and to the reactor of gold precipitation from solution. A filter is installed inside the leaching reactor for separation of gold- containing solution from precipitate and its washing, dividing it into the zone of reaction and zone of filtration. The filtration zone of the leaching reactor is connected through a pipe-line to the gold precipitate reactor chamber, which at the same time serves as an accumulator of the gold-containing solution and device for washing of precipitated gold. The leaching reactor and the gold precipitation reactor are made as sealed chambers. The vessels for reagents and washing solutions, leaching reactor and precipitation reactor are connected through pipe-lines to the gas evacuation and absorption system. EFFECT: enhanced degree of gold extraction and environment safety. 4 cl, 1 dwg
