In the second stage, the white metal is oxidized to blister copper which contains about 0.5% sulfur and 0.2% oxygen. In the converter slag, the copper content is higher, may reach 2–15%. The copper exists in forms of dissolved Cu 2 S, entrained droplets of matte, white metal, Cu 2 O, and blister copper.
Other articles where Blister copper is discussed: copper processing: Roasting, smelting, and converting: remaining values), leaving a “blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.
Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a “blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.

No. 1 copper scrap has a minimum of 99% copper and is often just remelted. No. 2 copper consists of unalloyed scrap, with a copper content of at least 94% with a nominal content of 96% Cu. Light copper scrap contains between 88% and 92% copper. These types of copper
Copper is one of the few metals that finds most widespread use in the pure form, rather than as an alloy. There are approximately four dozen different wrought alloys that contain a minimum copper content
Copper, chemical symbol Cu, is a shiny, red-orange metal that has a wide range of applications. The price of copper is primarily driven by the availability of substitutes, the global supply and
The blister copper is recovered and is then subjected to another the smelter pays the miner approximately 96 percent of the value of the contained copper content in the concentrate, minus
The blister copper produced by this process is 99% pure copper. The name ‘blister’ copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper
Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper
However, considering the quality of blister copper and slag containing copper, the CSCu, RCaFe and T should be controlled at about 0.20%, 0.4 and 1526 K, respectively, and the CO should be
Apr 23, 2019· This, together with a lower supply of blister copper amid maintenance at smelters, drove refineries to lower offers of refining charges (RCs) for blister copper, an SMM survey found on Tuesday April 23. As of April 23, RCs for imported blister copper
The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis.
