The slag had a composition of Co: 0.45%, Cu: 3%, Fe total: 47%, Ni: 3.5%, and S: 3%. Although the conductivity of the commonly used conducting alloy (1350) is only around 62% of annealed copper, it is only one third the weight and can therefore conduct twice as much electricity when compared with copper of the same weight. LME Copper contract specifications. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The main drawback in the current process is that the final flotation tailings grades are in excess of 0.9% Cu. Secondary copper smelters are also a source of copper slag. Nano silica, silica fines and micro silica are added to commercial cements. Using converter slag from a nickel-copper plant, tests were carried out, in 1990, on a 100 kVA furnace (operated at 30 kW) and on a 200 kVA furnace (operated at 85 kW), at low additions of reductant (in order to minimize the reduction of iron).

Copper slag is a by-product obtained during smelting and refining of copper. Separating copper and arsenic has always been a major problem in the copper slag flotation process, which influences copper slag utilization and the environmental safety. It consists of 99.9 percent copper, and is available in six tempers designated by ASTM B370 as: 060 (soft), H00 (cold rolled), H01 (cold rolled, high yield), H02 (half hard), H03 (three quarter hard), and H04 (hard). Manufacturer Information. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated). Copper slag is a waste during pyrometallurgical produc-tion of copper from copper sulfide concentrates, about 2.2 tons of which being generated per ton of metal copper production. No. Copper Slag Copper slag (air-cooled and granulated) suitable for use as granular road base material has suitable engineering properties for use in embankments or fill applications. The copper most commonly used for sheet and strip applications complies with ASTM B370. (3) Reverberatory copper slag (copper slag derived from reverberatory furnaces used for the smelting of copper concentrates) (4,5) is covered by conventional specifications for granular aggregate in Michigan. Its sharp, hard cutting edges provide a fast cleaning action and is one of the most economical expendable abrasives available for cleaning steel surfaces where recovery and reuse are not practical. The copper sulfide is removed and the remaining slag is discarded. During smelting, impurities become slag which floats on the molten metal. Every metal traded on the LME must conform to strict specifications regarding quality, lot size and shape.
