Nov 11, 2020· With conversion of copper smelting plants to autogenic melting the problem arises of separate treatment of converter slag (CS). Almost all plants converted to autogenic melting use slag flotation [1,2,3,4,5,6,7,8,9,10].Sometimes they float a mixture of furnace and converter slags after granulation [] of a mixture of CS and original ore in different ratios [].
Jan 06, 2021· A small amount of slag is sold for railroad ballast and for sand blasting grit. A third product of the smelting process is sulfur dioxide, a gas that is collected, purified, and made into sulfuric acid for sale or for use in hydrometallurgical leaching operations. Following smelting, the copper matte is fed into a converter.
Copper and nickel slags are produced by: 1. roasting, in which sulfur in the ore is eliminated as sulfur dioxide (SO2); 2. smelting, in which the roasted product is melted in a siliceous flux and the metal is reduced; and 3. converting, where the melt is desulfurized with lime flux, iron ore, or a basic slag and then oxygen lanced to remove ...
The minerals are partially oxidized and melted, resulting in segregated layers. The matte layer refers to the iron-copper sulfide mixture which sinks to the bottom. The slag, which refers to the remaining impurities, floats on top of the matte. The slag is discarded …
