copper slag specification

Sinopsis

Copper slag is a by-product obtained during smelting and refining of copper. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below. The copper sulfide is removed and the remaining slag is discarded. The copper most commonly used for sheet and strip applications complies with ASTM B370. Much later came brass (copper and zinc), and – in the modern age – cupronickel (copper and nickel). Copper recovery from the slag is expected to consist of o Loading of slag into 30t trucks carried out by Anglo 55 York St., Suite 401 Toronto, ON, M5J 1R7 Tel 647-632-3444. We offer Copper slag, which is widely used in removing mill scale and rust, paint. Along with copper, aluminium has an electrical conductivity high enough for use as an electrical conductor. Types of Copper and Properties. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The production of nano silica from the dissolution of olivine is an economic option when compared with the traditional commercial method which requires high temperature vapourization of silica. (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. 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). Copper slag is a by-product of copper extraction by smelting. 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). Nano silica, silica fines and micro silica are added to commercial cements. We are leading manufacturer, Supplier & exporter of Copper Slag. 1.1. LME Copper Contract specifications. GSR - SDS 005. For full contract specification details, please refer to the LME Rulebook and for other information, please refer to our disclaimer page.. 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). 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. 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. Copper can be combined easily with other metals to make alloys. 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. Copper Slag. Nickel-copper converter slag 'A'- 100 kVA and 200 kVA. The offered products are widely demanded in domestic as well as international markets. The first alloy produced was copper melted with tin to form bronze – a discovery so important that periods in history are called The Bronze Age. The main drawback in the current process is that the final flotation tailings grades are in excess of 0.9% Cu. First, the physical fraction consists of mechanically trapped solids, while, second, chemically dissolved particles constitute another possibility. 2). 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. copper, slag nearly saturated with magnetite and silica with high copper oxide activity 10-2–10-3 and gas phase with partial pressure of oxygen about 10-2 Pa and partial pressure of sulphur dioxide in the order of between 104–105 Pa in El Teniente converter. Copper slag is an abrasive blasting grit, made of granulated slag from metal smelting processes using iron. 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. This copper content is considered too high to be lost in the final waste stream. Manufacturer's Name PT. Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. 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. No. View Complete Details. 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. copper slag corresponds to 30–40 % iron, 35-40% silica, less than 10 % of alumina and calcium oxide and copper content is around 1 %Cu, similar to the ore mined. Manufacturer Information. Standard Specification for Copper-Zinc-Lead Alloy (Leaded-Brass) Extruded Shapes: B570 - 16: Standard Specification for Copper-Beryllium Alloy (UNS Nos. Secondary copper smelters are also a source of copper slag. Smelting Gresik Smelter and Refinery Address Desa Roomo, Kecamatan Manyar PO. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. C17500 and C17510) B927 / B927M - 17 Slag from ores that are mechanically concentrated before smelting contain mostly iron oxides and silicon oxides. The slag had a composition of Co: 0.45%, Cu: 3%, Fe total: 47%, Ni: 3.5%, and S: 3%. Copper Slag . Copper losses in the slag can generally be split into two categories. Global Copper Slag Market 2020 Understand the Influence of COVID-19 Latest Report on Copper Slag Market Forecast 2026- Covid-19 Update. copper slag crushing unit in tamilnadu . 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. Before the electric furnace, the fayalite slag shows a share of around 65–80% in mechanical losses. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte. The waste copper slag can be used as abrasive tools, road construction, and ballast. Copper slagproduced during the matte smelting and refining ofcopperore, during which, the iron present in thecopperconcentrate combines chemically at 1200°C with silica present in flux materials such as riversand/silicasand/ quartz fines to form iron silicate, which is termed ascopper slag. The latest report on Copper Slag Market provides a comprehensive assessment of the Copper Slag world market sorting by application, type and region.

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 . This is an environmentally friendly medium for surface preparation and produces a clean surface for coating adhesion. Box 555 Gresik 61151 Jawa Timur - Indonesia Telephone Number : 62-31-397-6458/59 Fax Number : 62-31-397-6460 1 and Fig. 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. 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. Copper slag is +2a form of olivine, a magnesium, iron and silicate mineral with the formula (Mg , Fe+2) 2 SiO 4. LME Copper contract specifications. This is a summary of the contract specifications.
