·Copper occurs in nature in the form of sulphide and oxide ores salt minerals and as native copper It is the second most used non ferrous metal in industry Boulamanti and Moya 2016 According to the United States Geological Survey USGS the 2019 global annual copper extraction was about 20 million tons Fig 1 The highest annual mining capacity was recorded
Mines are faced with numerous challenges such as falling raw material prices declining metal grades in the ores and higher energy prices Especially because ore processing is particularly energy intensive the industry is again focusing on the saving of energy This report shows what are the key energy saving considerations in the copper and gold mining sectors
·This paper provides an overview of hydrometallurgical copper extraction studies in which liquid extraction technology has been used with four copper deposits of different compositions The sulfuric acid consumption rate and copper extraction efficiency which are dependent on the initial content and forms of calcium compounds and other impurities in ore
·BacTech Enviromet Corp in conjunction with Mintek 14 has developed proprietary technologies for the high temperature leaching of copper concentrates Working in conjunction with Industrias Penoles SA de CV one of Mexico s largest and most diverse mining companies they operated a metric tons per day mt/d stirred tank copper concentrate
·The main raw material is copper sulfide ore and high grade copper oxide ore can also be smelted in the pyrometallurgical process The mining grade of copper sulfide is 2% and the average mining grade is approximately % The mined ore is crushed and pulverized Then flotation will separate the copper sulfide concentrate
·In the gold mining industry smelting is the final stage of extracting pure gold from ore This process involves melting the gold laden material to separate the precious metal from impurities Here we ll delve into the two primary methods used to smelt gold loaded carbon from cyanide leaching plants desorption electrolysis and direct smelting Desorption
3 ·Copper ore beneficiation usually adopts gravity separation flotation magnetic separation leaching and other JXSC supports customized copper processing plant and equipment fully suitable for separating copper oxide ore azurite cuprite and malachite ; copper sulfide ore chalcopyrite bornite and chalcocite and natural copper
·Nchanga copper ore is a complex mixture of sulphide and oxide minerals and processing involves sulphide flotation and the sulphide rougher/scavenger tails rich in oxide minerals acid soluble
·In the future innovative technologies to develop inexpensive easy to obtain high quality and lasting membranes are needed The IX process has a large capacity and high efficiency and can be used to recover precious metals However it involves long treatment cycles and produces large amounts of recycled waste liquid
·The pregnant liquors and wash waters obtained from the vat leaching operation are pumped to a precipitation plant where the copper is recovered by use of iron scrap Inspiration Consolidated Copper Co The ore treated in the vat leaching operation of the Inspiration Consolidated Copper Co fig 22 is mixed oxide sulfide ore
·Figure 1 Overview of copper production Benefication process Figure 2 Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting Smelting these materials would require too much energy and very large furnace capacities The copper ore coming from the mine 1 %
·Besides customers are increasingly aware of the carbon footprint of their supply chain Fahr et al 2016 Life cycle assessments considering embodied energy and CO2 emissions of the copper mining processes have been carried out Norgate and Haque 2010 Moreno Leiva et al 2017 The results showed that the crushing and grinding processes have
· ₂ These oxidised copper minerals are found in weathered regions of most copper sulphide ore bodies The overlaying oxidic ore is usually stockpiled after it is removed from the sulphide lode and left unprocessed as the sulphide ore is simpler to recover by conventional flotation procedures and thus more attractive to the plant operator
2 ·Copper processing is a complicated process that begins with mining of the ore less than 1% copper and ends with sheets of % pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy
·c Different processing plants; d One plant receiving ore from different mines; e Production losses due to ore dilution; f Inefficient plant process; and g Different ore storage points To counter this complexity a systematic approach is required for the metal content determination [5] Cawood [6] classified the losses as real and apparent
