Concentrate and oxygen-enriched air 30-35 O2 enter the smelting furnace through vertical lances and are smelted to produce a matte of 65 to 69 Cu and low-copper slag. Fuel must be burned to satisfy the heat balance in the smelter chamber.
Oct 01, 2003 Smelting of sulphide ores result in a 4050 copper matte grade plus a discard slag while the smelting of oxide ores yields impure black copper about 95 Cu and slag. It is interesting that the furnace may be used to treat both ores types together Ullmann, 1995 .
copper smelting in Southern Africa. Ancient History of Copper Smelting Smelting history goes back at least 6000 years to the copper smelters of the Timna valley near Eilat in Israel. Copper is the worlds oldest metal and was used more than 5000 years ago for
Pyrometallurgical production of copper generates two slags smelting furnace slag and converter slag which contain 0.5-2 Cu and 2-8 Cu, respectively. The following three methods are generally utilized for recovering the copper from these slags on an industrial scale i recycling of the converter slag to the smelting furnace,
Feb 06, 2017 The products, refined copper and refinery-slag, together contain quantities of arsenic, antimony and bismuth equal to those present in the blister-copper subjected to the operation. In the tables on p. 663 the products of refining are calculated from the working-results on 100 tons of blister-copper.

II. After the cessation of smelting activities in the 1950s, new smelters were erected in 1963, consisting of a Cu smelter with reverbatory furnace and a Pb smelter with a shaft furnace. During the 1980s, a Slag Mill was built to re-process old copper reverbatory slags by converter techniques producing granulated slag, which is passed
Jan 01, 2014 Slag from copper-smelting operations usually contain between 1.5 and 8 copper depending on process used. After internal recycling, reduction andor settling, the slag contains between 0.7 and 2 Cu and is often discarded. It is estimated that about 2.2 t of slag is generated per ton of copper produced.
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.
