Smelting Copper Using a Reverberatory Furnace A reverberatory furnace is fabricated from steel beams into a rectangular structure which is lined outside and inside with firebricks. Fossil fuel and/or oxygen fired burners provide the exothermic heat required to melt the copper ore which is supplied by conveyor to a gas tight hopper.

This mechano-chemical process can leach 97-99% copper directly on site, from concentrates as low as 5% copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenic-ladden concentrates.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

In general, direct smelting can be divided into two categories: (1) submerged smelting, as in the QSL and Isasmelt processes, in which the refining reactions occur in a liquid (i.e., molten metal, matte, or slag), and (2) suspension smelting, as in the KIVCET process, in which the reactions occur between gases and solids.

The copper matte generated by the smelting furnace contains 58-60% copper. The molten matte is taken to another furnace called a converter to have the remaining iron and sulfur burned off. This product is referred to as blister copper, which contains 98% copper, and taken to the anode smelter.

The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this smelting process the copper is about 99% pure.. Oxide Ore. The copper-bearing solution is collected and pumped to the extraction plant where it is purified.

The copper blister is first pre-refined to get copper anodes, which have a metal content of 99.5%; these anodes are then refined by an electrolytic process to obtain copper cathodes, which have a metal content of 99.99% and represent the copper metal in its pure form. Aluminium is obtained by the electrolytic refining of alumina.
WhatsApp
This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining. At this point, the copper is cast into anodes, the shape and weight of which are dictated by the particular electrolytic refinery. Leaching

The smelting process will include the use of direct to blister flash (DBF) smelting technology, wherein the copper concentrate will be processed by flash smelting to produce blister copper (98% Cu). The produced blister copper will be transferred for anode furnace treatment, which refines and casts them as saleable anodes.
