Thecopper orebecome moltencopper dropletsthat fall to the bottom of the furnace forming a moltencopper layerwith a slag floating on top of it. The moltencopperis tapped and sent through the sameprocessesas the reverb smeltedcopper, except for the converter stage, as it has been already converted to blistercopperin the flash furnace.

Copperprocessing, the extraction ofcopperfrom its ores and the preparation ofcoppermetal or chemical compounds for use in various products. In its pure form or as an alloy,copper(Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and ...

Leaching process for copper ore includes acid leaching and ammonia leaching. Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.

Thecopper miningindustry is an important source of wealth and employment in Arizona (AZMiningAssoc., 2011). Yet, without proper planning and environmental monitoring,miningcan also be a source of contamination that impacts the health of neighboring communities and the environment (USEPA, 2011).

Copper- From Beginning to End.Copperis a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Introduction toCopper SmeltingTechniques.Copperore typically contains only about 0.6% of the actualcoppermineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pitmining, the later accounting for 90% of the ore used insmelting.

Copperis usually found in nature in association with sulfur. Purecoppermetal is generally produced from a multistageprocess, beginning with theminingand concentrating of low-grade ores containingcoppersulfide minerals, and followed by smelting and electrolytic refining to produce a purecoppercathode.

Refiningimproves the ductility ofcopperso that extremely fine wires can be drawn. Impurities increase the chance that the wire will break during the drawingprocess.Copperconducts electricity Only silver conducts electricity better thancopper, traditionally Silver cost 40 times the price ofCopper.
