Abstract

В способе получения металлов платиновой группы (МПГ) и феррохрома из содержащей МПГ хромитовой руды приготовляют концентрат, который содержит большую часть МПГ и хромита из руды, и этот концентрат подвергают нагреванию, чтобы высушить и/или предварительно нагреть концентрат, после чего предварительно нагретый концентрат плавят в восстановительных условиях в плавильной печи (14) постоянного тока с получением расплавленного металлического сплава, содержащего МПГ из сырья, и расплавленного шлака, содержащего хром из сырья. Расплавленный шлак выпускают из плавильной печи (14) в шлаковую печь (16) переменного тока, где восстанавливают железо и хром с получением феррохромового сплава. МПГ получают из металлического сплава, выпущенного из плавильной печи (14), с применением гидрометаллургических процессов.In the method of producing platinum group metals (PGM) and ferrochrome from the MPG-containing chromite ore, a concentrate is prepared which contains most of the PGM and chromite from the ore, and this concentrate is heated to dry and / or pre-heat the concentrate, after which the preheated concentrate is melted in reducing conditions in a direct current melting furnace (14) to produce a molten metal alloy containing PGM from the raw material, and molten slag containing chromium from the raw material. The molten slag is released from the smelting furnace (14) into the slag furnace (16) of alternating current, where iron and chromium are reduced to produce a ferrochrome alloy. PGM is produced from a metal alloy released from a smelting furnace (14) using hydrometallurgical processes.
