Abstract

Даний винахід стосується вилучення металів з вогнетривких сульфідних і вогнетривких вуглецьвмісних сульфідних руд. Спосіб вилучення благородних металів з подрібненої вогнетривкої сульфідної руди, що містить благородні метали, що включає біовилуговування для окислення сульфіду заліза і гідрометалургійну обробку для вилучення благородних металів, причому перед біовилуговуванням проводять розділення подрібненої вогнетривкої сульфідної руди на високодисперсні фракції і крупну фракцію, здійснюють утворення маси з крупної фракції, біовилуговуванню піддають отриману масу, а гідрометалургійній обробці для вилучення благородних металів піддають біовилужену руду, проводять обробку дрібних фракцій для вилучення благородних металів, що містяться в них.
