This paper presents the results of multi-linear regression analysis (MLRA) of the slag composition (SiO2, FeO, Fe3O4, CaO, Al2O3) and the content of copper in the matte on resulting copper content in the slag during smelting of the sulfide concentrates in the reverberatory furnace.
Slag floats on the surface of the molten metal, protecting it from oxidation by the atmosphere and keeping it clean. Slag forms a coarse aggregate used in certain concretes; it is used as a road material and ballast and as a source of available phosphate fertilizer .
The slag is a dense, glassy material of mostly iron and silica. It is tapped from a hole in the upper part of the furnace wall and carried outside to the slag dump to cool.A slag pour resembles a man-made lava flow and can be quite spectacular at night.
In the smelting process, slag compositions essentially determine the amounts of gold left in slag, hence, the recovery of gold. To maximum the recovery of gold, it is of great importance to optimize the slag composition so as to minimise the gold content in slag.

The chemical composition of the slag is dependent upon the composition of the available iron ores, flux stones, and fuels, and on the proportions required for efficient furnace operations.
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals.
