Silica is second only to oxygen in weight percentage of the Earth's crust. It is found in an enormous diversity of silicate minerals. The water soluble ionic forms of silicate are the sodium salts of the general form [SiO 2 (OH) 2] 2-but, depending on the pH and concentration, other polymerized species can .

Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal with excellent electrical conductivity, and finds extensive use as an electrical conductor, heat conductor, as a building material, and as a component of various alloys.
Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible, which makes possible selective oxidation of Cu 2 S to low-sulfur copper without the formation of Cu 2 O. At low pO 2, molten matte and molten silica-saturated slag will coexist, the iron content of .
HM contains carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulphur (S), trace metals and some gases besides iron (Fe) which is the main constituent of HM. P and S are considered as impurities in the HM. HM contains around 3.5 % to 4.5 % of C with S content less than 0.05 % and P .

The thermodynamic study of the copper losses in the slags from El Teniente Process may be discussed on the basis of the Cu-Fe-S-O-SiO 2 system, in which the metals, sulphur and silica represent the major components of the condensed phases and oxygen is the major component of the gaseous phase. From the available thermodynamic data and phase
