METHOD FOR REDUCING NON-FERROUS METAL CONTENT IN SLAG IN THEPRODUCTION OF NON-FERROUS METALS OCCURRING IN SUSPENSION SMELTING FURNACE |
摘要 |
The present invention relates to a method, whereby the non-ferrous metal content of the slag generated in the production of non-ferrous metals such a s copper or nickel in a suspension smelting furnace is reduced by charging metallurgical coke, with a size ranging from 1 - 25mm, into the furnace. Baffles can be positioned from the roof of the furnace downwards, by means o f which small particles containing copper and nickel are prevented from drifti ng to the back of the furnace and being tapped with the slag. The baffles force the small particles to settle in the reduction zone of the furnace.
