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.
