utilizes one TBRC to treat a high-grade copper concen­ trate. More recently Boliden4 commissioned a copper TBRC at their Ronnskar smelter in Sweden. Although it has an energy consumption higher than flash smelting processes, the TBRC is a compact smelting unit which has a high degree of flexibility and can handle a relatively wide range

The final products of smelting and electrolytic refining are cathodes, cast often in the form of copper wirebars and cakes.*. The casting are subsequently worked in various ways into wrought forms. Re-melted cathodes may also be cast into ingot bars suitable for the preparation of alloys. * See CDA Publication No. 52, Introduction to Copper .

The matte, about 45 to 55 percent copper and the remainder iron silicate slag, is formed in a very fast, almost instantaneous reaction; hence the name "flash smelting.". The matte sinks through the lighter slag layer and flows down the. inclined crucible. Conversion to copper proceeds in a zone around position two.

The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early '60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent equilibria.

The smelting process uses an electrical current to heat the metal. This process is called electrolysis. The metal is placed in a crucible, or melting pot, and melted down. Once melted, the impurities in the metal rise to the surface and are skimmed off. The pure metal is then poured into molds to cool and solidify.
