Copper processing or pyrometallurgical processes employ hightemperature chemical reactions to extract copper from its ores and concentrates generally these processes are used with copper sulfides and in some cases highgrade oxides depending on the copper mineral and the type of equipment pyrometallurgical recovery may take as many
Processes copper mining and production copper is found in natural ore deposits around the world this page explains copper mining the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living
In this process copper ore is mined crushed ground concentrated smelted and refined the mining crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it
Copper from beginning to end copper is 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 10000 years ago and as alloyed in bronze coppertin alloy about 3000 bc was the first engineering material known to man
Because copper is a highly efficient conductor of electricity and heat it is used in renewable energy systems to generate power from solar hydro thermal and wind energy across the world copper helps reduce co 2 emissions and lowers the amount energy needed to produce electricity in many renewable energy systems there is 12times more

Place these products in the extraction process in ascending order of copper content use the flow chart as a guide matte ore cathode copper blister anode copper copper concentrate fire refined copper use a periodic table to find the atomic masses of the elements in cuprite and chalcocite then work out the percentage of copper in each mineral
recycling a tonne of copper uses 20 of the energy that would be used to mine and extract the same copper the copper recycling process has much in common as that to extract it but requires fewer steps highpurity copper is melted in a furnace and then reduced lowpurity copper is refined through electroplating in sulfuric acid
Jul 09 2020 embodied energy use starts with the fuel used by giant mining machines such as the 03 mpg caterpillar 797f which can carry 400 tons of ore there are also energy costs for electricity at the mine site in remote areas often dieselpowered to run machines that crush rocks as well as the energy costs in producing and using chemicals for
The early development of copper probably was most advanced in egyptas early as 5000 bce copper weapons and implements were left in graves for the use of the deaddefinite records have been found of the working of copper mines on the sinai peninsula about 3800 bce and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining
Energy and environmental profile of the us mining industry the concentrate is thickened by settling the thickened concentrate is pumped out dewatered by a filter press and dried the concentrate is then fed to a roasting operation 6123 lead ore processing lead ore beneficiating includes milling concentration and sintering

Sep 26 2019 copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw mined state into a purified form for use in many industries copper is typically extracted from oxide and sulfide ores that contain between 05 and 20 copper
