Smelted Minerals. The smelted minerals accumulate in the bottom of the furnace in two layers: the slag on top, and the copper-bearing matte on the bottom. The slag and matte are tapped off through portals in the wall of the furnace. The matte, which may be up to 70% copper is then fed to a converter.

In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes from partial oxidation of the sulfide charge and from burning external fuel. Most of the iron and 10/86 (Reformatted 1/95) Metallurgical Industry 12.3-1

The hydrometallurgical smelting process is a roast, leach and electro-winning, or RLE, process. In this process, zinc concentrate is first oxidized in the roaster and the gases generated are cleaned and sent to the sulphuric acid plant. The primary output from the roaster, called calcine, is sent to the leaching plant to produce a zinc sulphate ...

ISA Process. Copper is electro refined from anode by means of electrolysis process using SS-blank as cathodes. Copper anodes and SS blanks are inserted in alternatively electro refining cells. By applying direct current to this cell, copper in anode is dissolved and deposited onto the SS-blank surface. Cu % in cathode is more than 99.99%.
