Copper production & environmental impact

At the end of this smelting process the copper is about 99% Oxide Ore. The copper-bearing solution is collected and pumped to the extraction plant where it is purified. It progresses through a number of steps that combine an organic solvent or sulfuric acid to the solution until the copper concentration is high enough for effective electro-plating. Refining Sulfide Ores. After smelting

Copper Smelting Slideshow

Slag from the smelting process can contain up to 20% copper. It's allowed to cool and then reused in the smelting furnace to control the temperature, or it's treated by grinding and flotation and fed back into the smelting process to recover additional copper. Slag. Blister copper is only 90% pure copper. This is not pure enough to be used in manufacturing. The blister copper is cast into

It is given the ground for preferableness of the pyrometallurgical method, which it is caused the next factors: a) variety of slag composition, forming on the Copper founding plants and b) necessity of its selective proceeding

CLEANER PRODUCTION GUIDELINES IN COPPER SMELTING …

COPPER SMELTING Copper can be produced either pyro-metallurgically or hydro-metallurgically. The hydrometallurgical route is used only for a very limited amount of the world's copper production and is normally only considered in connection with incite leaching of copper ores; from an environmental point of view, this is a questionable production route. Several different processes can be used

A copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper. Flue gas discharged from the furnace is treated to produce sulfuric acid. Furthermore, waste liquid discharged during the production of sulfuric acid is treated to produce gypsum, and the gypsum thus produced is recycled to the furnace as a flux.

Copper Processing

Smelting is the process of taking the copper concentrate (CuFeS2) and reacting it with SiO2, and O2 to produce slag (waste), copper matte and sulphur dioxide (gas) Too much silica results in the copper being oxidised Too quickly. The matte copper is further treated in a copper converter. Original Description. Copper Processing.
