Copper can be extracted using various combinations of pyro- and hydrometallurgical methods. The main primary processing route is the smelting of sulfide concentrate to Cu 2 S-FeS matte followed by the converting of matte to blister copper that is fire-refined and electrorefined, and this process route

2010-4-9 There are several methods of copper smelting, the popular ones being reverberatory smelting and oxygen flash smelting. Both methods require the resultant molten copper to be further processed to achieve a grade of 99.9% pure copper. During the process, the gas given off is converted to sulphuric acid, which can be used in the plant or sold off as a by-product. This is another article in my series on the smelting of metals, this one focusing on the smelting of copper.

2021-1-13 The predominant copper process is reverberatory furnace smelting of sulfide concentrates to produce matte and slag, followed by treatment of the matte in converters to form blister copper. The offgases from the reverberatory furnace are usually not more than 2 percent SO2, and of varying SO2 content from the converters, precluding economic sulfur recovery in most cases.
Read More2015-9-10 Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper.

The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron

2021-1-21 The Romans improved on the early primitive methods, but without altering the fundamental principle; and, as already mentioned, they successfully smelted sulfide ores, which would have defied the more ancient metallurgists. In Britain there has been found in Anglesey a number of circular cakes of copper which were cast in Roman times.

2021-1-13 Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at ...
