Description

Изобретение относитс  к области гидрометаллургического извлечени  цветных металлов, в частности меди.This invention relates to the field of hydrometallurgical extraction of non-ferrous metals, in particular copper.

Известен способ переработки окисленных и смешанных медных руд, включающий выщелачивание раствором серной кислоты, цементацию меди из раствора осадителем и флотацию цементной и сульфидной меди.There is a method of processing oxidized and mixed copper ores, including leaching with a solution of sulfuric acid, cementation of copper from solution with a precipitator and flotation of cement and sulfide copper.

Предложенный способ отличаетс  от известного тем, что провод т предварительное измельчение осадител  совместно с восстановителем , причем в качестве восстановител  используют сернистый натрий. Это позвол ет повысить извлечение цементной меди при флотации .The proposed method differs from the known one in that the precipitator is preliminarily crushed together with a reducing agent, and sodium sulphide is used as the reducing agent. This makes it possible to increase the recovery of cement copper during flotation.

В предложенном способе повышение эффективности действи  осадител  (губчатого железа , чугунной стружки и др.) при цементации меди достигаетс  добавкой в цикл измельчени  осадител -сернистого натри  при расходе его 3-4 кг. Расход осадител  зависит от типа осадител  и состава руды.In the proposed method, an increase in the efficiency of the precipitator (sponge iron, cast iron shavings, etc.) during the cementation of copper is achieved by adding sulphuritic sodium to the grinding cycle at a flow rate of 3-4 kg. The precipitator consumption depends on the type of precipitator and the composition of the ore.

Результаты сравнительных лабораторных опытов на примере руд Джезказганского месторождени  в услови х стандартного режима и с подачей сернистого натри  приведены в таблице.The results of comparative laboratory experiments on the example of ores of the Dzhezkazgan deposit under the conditions of the standard regime and with the supply of sodium sulfide are shown in the table.
