The viscosity of smelting slags from the Glogow copper plant in Poland was measured using a concentric cylinder viscometer. These slags contain typically 45 pct SiO2, 16 pct CaO, 8 pct MgO, 11 pct Al2O3, and only 5 to 7 pct total iron. The viscosity was measured as a function of the CaO, MgO, SiO2, Cu2O, Cr2O3, and Fe3O4 contents in the temperature range from 1473 to 1623 K. Silica and ...

Read MoreThe barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
