Method for producing high-grade nickel matte from at least partly pyrometallurgically refined nickel-bearing raw materials

摘要

The invention relates to a method for producing high-grade nickel matte and slag in a combination of a suspension smelting furnace and some other furnace without charge-type converting, so that at least part of the concentrate and/or ore fed into the process is first refined pyrometallurgically into nickel matte, which then is fed into the suspension smelting furnace, where the high-grade nickel matte proper is produced.
