The copper(II) ions are removed again from the organic solvent by reaction with fresh sulfuric acid, producing a much more concentrated copper(II) sulfate solution than before. Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).
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.
Smelting, Refining and their Products. ... each carrying about thirty-six pairs of impure copper slabs which are the anodes, and thinner sheets of pure copper; it is on the faces of the latter that additional pure copper is deposited as the anodes are electrolytically decomposed.

SuperbMelt metal melting furnaces are widely used in various of metals smelting, such as gold, silver, copper, platinum etc, from 1kg to 250kg. Adopt IGBT induction technology and optional PLC control system to achieve speedy melting and …
The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ∼50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Unlike the system for lead, the copper and …
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from …
Sulfide Ore: The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this melting process the copper is about 99% pure. While this may sound high, it is still not pure enough for electrical applications, so further processing is required.

In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper. In these operations some of the copper is oxidized to cuprous oxide …
Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
Some typical base metals used in smelting include aluminium, bronze, silver and copper. The challenges of smelting. Smelting can be a very challenging procedure.
