| description | FIELD: metallurgy.SUBSTANCE: method involves processing of base material during heating in water vapour atmosphere and further leaching of precious metals from processing product in solutions of reagents. Besides, processing of base material is performed in water vapour atmosphere, which is mixed with oxygen at the temperature of 300-500°C at oxygen content in gas mixture within 10-20%. Waste gases released during the processing are brought into contact with the solution that is combined with a leaching solution.EFFECT: decrease of temperature and reduction of costs at preparation of refractory ores and concentrates to leaching.1 tbl, 1 ex
Изобретение относится к металлургии благородных металлов, в частности к способу извлечения благородных металлов из руд и концентратов по схеме обжиг-выщелачивание. Способ включает обработку исходного материала при нагреве в атмосфере водяного пара и последующее выщелачивание благородных металлов из продукта обработки в растворах реагентов. При этом обработку исходного материала проводят в атмосфере водяного пара в смеси с кислородом при температуре 300-500°C при содержании кислорода в газовой смеси в пределах 10-20%. Отходящие при обработке газы приводят в контакт с раствором, который объединяют с раствором выщелачивания. Техническим результатом изобретения является снижение температуры и затрат при подготовке упорных руд и концентратов к выщелачиванию. 1 табл., 1 пр. |
