Document Type and Number:
Japanese Patent JPH06502220
Kind Code:
A
Abstract:
A process for treatment of zinc sulfide or other zinc bearing feed materials in conjunction with an iron sulfide containing mineral or compound to effect a separation of zinc from iron by fuming on either zinc and sulphur vapor or zinc sulphide vapor. The vapor is stripped and transported by a carrier gas from the mineral or a molten matte formed from the mineral. The process is operated at a temperature in the region of 1250 DEG to 1400 DEG C. and at a partial pressure of oxygen in the region of 10-7 to 10-11 bar. The process is conducted in the presence of a liquid matte phase which contains at least iron sulphide and which is intimately mixed in a bath with a slag phase.
