Copper Slag - an overview | ScienceDirect Topics
Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper concentrates now available.

Copper extraction - Wikipedia
Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.
Copper Slag - Loose Copper Slag Manufacturer from Ahmedabad
Copper slag is a by-product produced during smelting of copper, which is then processed into abrasive products. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water. This cooling process fractures the slag into coarse, angular particles making it an ideal choice in many applications.

Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is …
What is copper tailing and copper slag? - Quora
In this context, “tailings” is waste rock at a mine after the ore has been processed to remove the metal. It has usually been pulverized to fine sand. “Copper slag” will be the slag skimmed off molten copper in a furnace. It is generally formed from limestone or phosphate rock added to the furnace,...

Sep 21, 2012 · A significant portion of the copper loss in discard slag from such furnaces is present as dissolved copper in the form of Cu 2 O, especially toward the higher oxygen potential range of operating furnaces (higher matte grades, Fe/SiO 2 > 1.5), or in the form of soluble copper oxysulfides when the slag is equilibrated with mattes of lower grade (mattes <65% Cu or >12% Fe).
Common Uses for Slag | National Slag Association
Electric Arc Furnace Slag (EAF or steel furnace slag) Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include

(SiO2, FeO, Fe3O4, CaO, Al2O3) and the content of copper in the matte on resulting copper content in the slag during smelting of the sulfide concentrates in the reverberatory furnace. When comparing results obtained with MLRA model calculations with values measured at industrial level high degree of fitting is obtained (R2 = 0.974).
ASARCO » Smelting
This combustion releases a tremendous amount of heat that sustains the high temperature in the furnace.The copper, iron, and silica form two layers at the bottom of the furnace. The lighter, top layer is a slag of mostly iron, silica, and other impurities. The bottom layer of mostly copper and some iron is called matte. The Acid Plant
BlastOne : Coal and Copper Slag Blasting Abrasive
All Coal & Copper Slag Abrasive Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As it burns, the residual ash becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media.
