was packaged with the 20 million tonnes slag stockpile. The cobalt grade of the slag ranged from % to % where as copper averaged %.The stockpile was created over a period of 60 years since 1935 by dumping the slag generated from the Rokana Copper Smelter. Anglovaal Mining of South Africa purchased this package in 1998.

A Study on Reduction of Copper Smelting Slag ...
Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about million tons of copper slag is generated annually in Korea. Oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia (MgO).
Ammoniacal System Mechanisms for Leaching Copper from ...
· In pyrometallurgical processes refining copper, the main source of loss in the conversion stage is from slag. This paper reports on research work treating converter slag containing high percentages of copper (36 wt%) using ammonium hydroxide at room temperature. Variables analyzed are solution pH, agitation, temperature, NH4OH .
Characteristics and utilisation of copper slag—a review ...
· Copper slags have been used as aggregate substitutes in hot mix paving. Aircooled slags can be used as coarse or fine aggregate, while granulated slags can be used as fine aggregate (Miller and Collins, 1976). Use of copper slag (15% mass) as a Portland cement replacement was reported by ArinoMoreno and Mobasher (1999).
Recovery of cobalt, nickel, and copper from slags, using ...
Copper sulphide and copper metal (with its inherent cobalt content), because of their higher densities and immiscibility with the slag, settle from the molten slag into the metal bath. Improving recoveries via this mechanism would involve decreasing the viscosity of the slag (by increased temperature or flux additions), and / or increasing the settling time to allow smaller droplets to fall.
