Abstract

Изобретение относится к способу переработки сульфидных руд, содержащих драгоценные металлы, таких как медные руды, содержащие никель. В соответствии со способом руду или концентрат (1), содержащий драгоценные металлы, выщелачивают (2) и железо, содержащееся в растворе, нейтрализуют в окислительных условиях посредством железистого рециркуляционного раствора (6), подаваемого рециклом на выщелачивание. Раствор (8) после операции выщелачивания и по меньшей мере часть осадка этого раствора переводят на операцию (5) химического превращения, куда содержащий железо сульфид (9) подают для преобразования имеющейся на операции химического превращения меди в содержащий драгоценные металлы концентрат (10) сульфида меди. Раствор (6), полученный на операции химического превращения, частично подают рециклом на предыдущую операцию (2) выщелачивания, а частично переводят на дополнительную обработку (11) компонентов, содержащихся в растворе.
