1. Способ переработки цинковых осадков, включающий солянокислотное выщелачивание, отличающийся тем, что осадок солянокислотного выщелачивания дополнительно выщелачивают царской водкой с получением золотосодержащего раствора и осадка хлорида серебра и свинца, затем из царсководочного раствора известным способом осаждают золото, а из осадка хлоридов серебра и свинца раствором ацетата аммония выщелачивают свинец и затем после отделения раствора ацетата свинца восстанавливают известным способом хлорид серебра, причем полученные осадки золота и серебра перерабатывают в отдельных циклах.1. A method of processing zinc precipitates, including hydrochloric acid leaching, characterized in that the hydrochloric acid leach precipitate is additionally leached with aqua regia to obtain a gold-containing solution and a precipitate of silver and lead chloride, then gold is deposited from the aquatic solution in a known manner, and silver and lead are precipitated with a solution of silver and lead ammonium acetate lead is leached and then, after separation of the lead acetate solution, silver chloride is reduced in a known manner, the precipitate being obtained and gold and silver are processed in separate cycles. 2. Способ по п. 1, отличающийся тем, что выщелачивание свинца осуществляют раствором ацетата аммония при соотношении СН3COOH : NH4OH : H2O = 1 : 0,76 : 3.2. The method according to p. 1, characterized in that the leaching of lead is carried out with a solution of ammonium acetate at a ratio of CH 3 COOH: NH 4 OH: H 2 O = 1: 0.76: 3.
