A process for the production of ferrous sulphide.

摘要

Ferrous sulphide is produced by forming a melt of a source of sulphur, suitably flotation grade iron pyrites, and a source of iron, suitably steel, in an electric induction furnace until reaction has ocurred, allowing a slag to form and removing the slag and pouring the residual ferrous sulphide product. Precautions are taken to protect the furnace circuitry from the pervasive effect of iron pyrites dust. The process may produce a ferrous sulphide product containing up to about 35% sulphur by weight with only low sulphur emission to the atmosphere.
