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 is an aggressive abrasive frequently used in new steel and steel maintenance applications. Its bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action, considerably increasing production rates.

Granulated copper slag is more porous and therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size (Emery, 1986, Hughes and Haliburton, 1973).
Feb 27, 2016· The last product is characterized for containing small amounts of gold and silver. The treatment of these products depends on the metallurgical extractive process of lead and copper. Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time.
Anodes cast from the nearly pure copper is immersed in an acid bath. Pure copper ions migrate electrolytically from the anodes to "starter sheets" made from pure copper foil or steel where they deposit and build up into a refined copper cathode. During this process, gold, silver and platinum may be recovered from the used electrolytic bath.
The lead, containing the gold, being the heaviest material in the slag will be on the very bottom. When the slag cools, the hardened slag is removed form the mold and tapped with a button hammer to break away the lighter material, leaving only the lead button. The .
Jan 24, 2015· The phases of copper slag, which contain gold and platinum are present in very less quantity with respect to volume percentage. The major phases, in the copper slag are fayalite and magnetite while spinel, ulvospinel, metallic iron, calcium oxide and barium sulphide are minor phases and all these are devoid of gold or platinum.
The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.
