· Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

A further development by Xstrata Technology is the ISASMELT™ process – continuous copper converting where granulated copper matte is converted into blister copper in an ISASMELT™ furnace. The blister is subsequently refined in an anode furnace. New slag systems have been developed to suit the continuous
Get PriceCopper slag, a by-product of copper pyrometallurgy, inevitably contains a certain amount of copper. Oxygen-enriched smelting technologies increase the copper content in slag indirectly because of the production of higher-grade matte. The effect of iron phase evolution on the copper content in slag during the slag cleaning process in an electric furnace was …
Get Pricethe Mansfeld copper-slags are used very seldom (LEEDER et al. 1989). So far, this particular copper slag has been used exclusively in road constructions. In view of restoration of the Mansfeld district, with the aim of reducing its dump areas, researches should be made so as to assure further applications of the copper slags.
Get Price· The copper slag has been found to contain high iron oxide and may be used as a source of iron in the manufacture of OPC. However, the presence of high iron in the slag hinders its bulk utilisation. The effect of copper present in the copper slag is invisible in the formation of clinker as the quantity of copper slag used in the raw mix for OPC
Get PriceUnconfined compression tests are conducted on specimens with different fly ash (10–40%) and dolime (0–20%) contents cured up to 28 days. A mix of 20% fly ash and 80% copper slag stabilized with 15% dolime was found to be the optimum for …
Get PriceRestoration architects recently found that a mixture of crushed walnut shells and copper slag at a pressure of approximately 200 psi was the only way to remove corrosion successfully from a mid-19th century terne-coated iron roof. Metal cleaned in this manner must be painted immediately to prevent rapid recurrence of corrosion.
Get PriceCopper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1.

Get Priceslag which is formed from the iron oxide and the rock residual in the concentrates. The process when operated as low as 1 150°C shows small pieces of metallic copper throughout the slag and visible by eye when breaking it up with a hammer. But with high viscosity the copper droplets cannot settle and agglomerate into large pools.
Get PriceKeywords: slag cleaning, copper smelting slag, flux, EPMA analysis In the copper smelting process, more than two tons of slag is produced with each ton of copper. Copper losses in smelting slags are made up of chemically soluble copper (≈ 30%) and as mechanically entrained matter droplets (≈ 70%). This is the key technical concern for
Get PriceThe development of copper smelting technology has experienced a long process,but now it's still mainly use pyrometallurgy,its copper production accounts is about 85% of the world's total Longjiang metallurgical chemical equipment (the following abbreviation Longjiang) reverberatory furnace and blast furnace are also dominated by pyrometallurgy.
Get PriceWhen the next layer is deposited, the entrapped slag is not melted out. Slag may also become entrapped in cavities in multi-pass welds through excessive undercut in the weld toe or the uneven surface profile of the preceding weld runs, Fig 2. As they both have an effect on the ease of slag removal, the risk of slag imperfections is influenced by
