بيت /production of copper matte
Seventeen copper smelters world wide utilize Outokumpu flash smelting. Historically this process uses fuel and preheated air to supplement the heat generated from the exothermic oxidation of CuS. A mediumgrade matte of 45% to 50% Cu is produced.

Copper refining: Pyrometallurgy. The matte layer, on the bottom, contains the copper, while the slag layer, on the top, contains the impurities. The slag is discarded and the matte is recovered and moved to a cylindrical vessel called a converter. A variety of chemicals are added to .

Abstract: The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and firerefining can use a limited amount of secondary materials. Molten copper can effectively

was originally developed for copper recovery. It has since been extended to nickel, zinc, and gold processing. This latest solution, the Outotec Nickel Matte Chloride Leaching Process, is suitable for nickel refining and is a highly flexible, calcium chloride based processing route for nickel matte and other nickelcontaining raw materials.

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. (Cu^{2}S + O^{2} → 2Cu + SO^{2}) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very .

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 sulphur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining.

After matte smelting and standard slag cleaning in submerged arc furnaces (SAF), the fayalitic slag still contains up to 1 % of copper and other valuable metals like nickel, cobalt or molybdenum. In addition future regulations may restrict the heavy metal contents both in the solid and eluate in slags used for construction purposes in the future.
