METHOD FOR PRODUCING HIGH-GRADE NICKEL MATTE AND METALLIZED SULFIDE MATTE

摘要

The present invention relates to a method for producing a high-grade nickel matte and a highly oxidized slag in a flash smelting furnace, and for reducing the slag from the flash smelting furnace and for sulfidizing the resulting matte in an electric furnace. The matte produced in the flash smelting furnace and in the electric furnace are both directly conducted to further hydrometallurgical treatment.
