Abstract

В процессе, установке и установке для получения золота и/или серебра для повышения извлечения в процессе сорбционного выщелачивания (10) при производстве благородных металлов, в котором эффективность процесса ограничивается, в частности, содержаниями органического углерода и/или сульфидной серы, присутствующими в сырье, таким образом, что в образующихся при сорбционном выщелачивании (10) хвостах накапливаются значительные остаточные количества благородных металлов, предусматриваются стадии переработки хвостов сорбции в качестве подготовки к окислительному обжигу (80), при котором хвосты сорбции обезвоживаются (18), высушиваются (24) и гранулируются (26); окислительный обжиг (80) обработанных хвостов сорбции и подача обожженных хвостов в последующий процесс выщелачивания или сорбционного выщелачивания (10).In a process, installation and installation for the production of gold and / or silver to increase the recovery in the sorption leaching process (10) in the production of precious metals, in which the efficiency of the process is limited, in particular, by the content of organic carbon and / or sulfide sulfur present in the feed, in such a way that significant residual amounts of precious metals accumulate in the tailings formed during sorption leaching (10), stages of processing of sorption tailings are provided as a preparation for oxidative roasting (80), in which the sorption tailings are dehydrated (18), dried (24) and granulated (26); oxidative roasting (80) of the treated sorption tailings; and supply of the burned tailings to the subsequent leaching or sorption leaching process (10).
