What is a Copper Slag (with pictures)wiseGEEK

May 25 2020 · Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore they produce a large volume of non-metallic dust soot and rock. Collectively these materials make up slag which can be used for a surprising number of applications in the building and industrial fields.

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica) calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces calcium carbonate is added as a flux to create the slag.

Each furnace is rotated by a hydraulic drive linked to the furnace by a chain. By rotat-ing the furnace one way or the other the operator can either pour the slag into the hauler pot or pour matte into a pot in the aisle. The maximum rate of slag skimming is control-led to minimize the copper content of the slag.

The Recovery of Copper from Smelting Slag by Flotation

Recover Copper from Reverberatory Furnace Slag. 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
