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. First, the physical fraction consists of mechanically trapped solids, while, second, chemically dissolved particles constitute another possibility. Dumping or disposal of such huge quantities of slag causes not only secondary environmental pollution due to the high content of Cu, Pb, Zn and S in copper slag, but . Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below. Copper slag is +2a form of olivine, a magnesium, iron and silicate mineral with the formula (Mg , Fe+2) 2 SiO 4. The latest report on Copper Slag Market provides a comprehensive assessment of the Copper Slag world market sorting by application, type and region. Copper slag is a by-product obtained during smelting and refining of copper. Bottom or coal slags are most often water-quenched. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte. Smelting Gresik Smelter and Refinery Address Desa Roomo, Kecamatan Manyar PO. Due to this high content of copper, the slags are milled and floated to recover the copper. Each LME tradeable contract is likewise governed by rules covering (but not limited to) prompt dates, settlement terms, traded and cleared currencies and minimum tick size. Before the electric furnace, the fayalite slag shows a share of around 65–80% in mechanical losses. Slag from ores that are mechanically concentrated before smelting contain mostly iron oxides and silicon oxides. Therefore, the purity of the quenching water and the cleanliness of the quenching basins have a significant effect on the cleanliness of the abrasive product. Our products are made up of using premium quality granulated slag in order to maintain their adherence to universally accepted norms. We offer Copper slag, which is widely used in removing mill scale and rust, paint. Secondary copper smelters are also a source of copper slag. The copper most commonly used for sheet and strip applications complies with ASTM B370. Copper Slag . Copper can be combined easily with other metals to make alloys. Manufacturer's Name PT. Copper slag is an abrasive blasting grit, made of granulated slag from metal smelting processes using iron. View Complete Details. Along with copper, aluminium has an electrical conductivity high enough for use as an electrical conductor. LME Copper Contract specifications. Nickel-copper converter slag 'A'- 100 kVA and 200 kVA. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. Box 555 Gresik 61151 Jawa Timur - Indonesia Telephone Number : 62-31-397-6458/59 Fax Number : 62-31-397-6460 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. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. Copper Slag. 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). Characteristics. Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. (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. The main drawback in the current process is that the final flotation tailings grades are in excess of 0.9% Cu. Cleaning of the primary slag is often economically justified and techniques including slow cooling and flotation, or pyrometallurgical or hydrometallurgical process are economical and have been adopted. Physical LME Copper contract specifications. The offered products are widely demanded in domestic as well as international markets. copper slag crushing unit in tamilnadu .

Manufacturer Information. This is a summary of the contract specifications. 1 and Fig. This product is appreciated for its hardness and free from silica. The copper sulfide is removed and the remaining slag is discarded.
