Mineral A mineral is a naturally occurring inorganic element of compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties Minerals may be metallic, like gold, or nonmetallic, such as talc Coal, oil, and natural gas are generally considered to be energy minerals

Introduction to Copper: Mining Extraction Copper Applications in Metallurgy of Copper Copper Alloys By Vin Calcutt The Copper Age The Bronze Age The Middle Ages and Later Mining Copper minerals and ores are found in both igneous and sedimentary rocks Mining of copper ores is carried out using one of two methods The process

Most of the copper ores contains only 0 4 -0 6 copper and other valuable metals as coproducts or byproducts, including molybdenum, silver, gold, bismuth, cadmium, and cobalt Copper Ore Mining Process For many sulfide copper minerals, the removal of copper is ultimately accomplished with fire, so it is known as a pyrometallurgical process

Separation of special copper ores such as those containing molybdenite or with high zinc or lead content Canada is also possible by flotation methods Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching

Even though these minerals occur in relatively small amounts they can often be economically recovered as by-products for the expense of mining, crushing, and grinding is absorbed in recovery of the copper A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1 copper, the porphyry copper
