摘要： In a flash smelting method of copper, a carbonaceous material, whose grain size is under 100 um and is in a proportion of 65% or more, and whose grain size is from 44 to 100 .mu.m and is in a proportion of 25% or more, and which has 80% or more of a fixed carbon content, is charged into a reaction shaft of a flash smelting furnace. It is possible to prevent the excessive formation and excessive reduction of Fe.sub.3 O.sub.4 in the slag. Copper loss, erosion of refractories and boiler trouble can be prevented.

摘要： In a pyrometallurgical smelting method of copper, the copper-ore and auxiliary fuel, such as carbonaceous material, is blown through an ore-concentrate burner into a reaction shaft. In an improved pyrometallurgical smelting of copper, the carbonaceous material is used to reduce the Fe.sub.3 O.sub.4 contained in the slag. The present invention provides an improved method for reducing the Fe.sub.3 O.sub.4 even in a case at a decreased amount of auxiliary fuel is to be decreased. The carbonaceous material is blown into a lower portion of the reaction shaft where the oxygen partial pressure is low.
