Laboratory and pilot plant investigations have indicated that copper recoveries of 50 can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper the percentage of copper in particles appearing to be copper-free was
Utilization of industrial waste is of utmost important due to pollution constraints. Large quantities of converter and anode slags are generated in different unit operations for the production of copper in I.C.C. Ghatshila. The converter slag contains about 2.75 copper, 0.9 nickel, 52.0 iron, and 0.6 cobalt and cannot be rejected due to its economic importance. X-ray diffraction XRD ...

In the second stage, called Copper Blow, sulphur is removed to get Blister Copper. Converter Slag is treated in a Slag cleaning furnace for recovery of copper. Blister Copper is further refined by oxidation and then by reduction to approximately 99.6 copper purity in the Anode Furnace, and cast as Copper Anodes.
Copper slag was subjected to in-depth mineralogical characterization by integrated instrumental techniques and evaluated for the efficacy of physical beneficiation and mixed meso-acidophilic bioleaching tests towards recovery of copper. Point-to-point mineral chemistry of the copper slag is discussed in detail to give better insight into the association of copper in slag.

Copper slag is a by-product of copper production from copper ore. For every ton of copper produced about 2.2 ton of slag is generated. At present, across the world around 33 tonnes of slag is generated while in India three copper producers Sterlite, Birla Copper and Hindustan Copper produce around 6-6.5 tonnes of slag at different sites.

A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag
3.5 COPPER SLAG Copper Slag, is a black glassy and granular in nature and has a similar particle size range like sand. It is an industrial by-product obtained during the smelting of copper. Copper slag used in this work was from Sterlite Industries India ltd, Tuticorin, Tamil Nadu, which was collected
recovery. The copper analysis remaining after conventional slag cleaning can be close to 1 while molybdenum is sometime found in a range of 0.2 to 0.4, depending on kind of mineral treated and technology used. These concentrations are higher in some cases than the analysis of the original ore and thus may warrant recovery by retreatment.
