·In addition copper and iron were obtained % and % respectively for a 15% solid to liquid ratio However copper and iron were obtained % and % respectively for a 20% solid to liquid ratio The extraction of copper increases up to 10% of the solid to liquid ratio; after that it will show a decreasing trend
·However Deng et al 2015 reported the extraction of copper from copper oxide ore by a zwitterionic reagent and it was observed that the leaching rate increased with decreasing particle size and
·Copper oxide ore or low grade copper sulfide ore exploited from the surface layer or corners in the mining of copper sulfide deposits is difficult to concentrate through mineral dressing In copper extraction usually aldoxime or ketoxime extractant is used for chelating extraction Fig 4 In extraction copper is enriched in the
Extraction of Copper The process of extracting copper from its ore is called the copper extraction process The extraction of Copper contains physical and electrochemical procedures Depending on the nature of the ore the source of the ore and the rules of a particular country the copper extraction process differ accordingly
·The increase of the temperature leads to an increase of copper extraction rates from low grade copper ore as shown in Fig 4 A maximum of % Cu was recovered at 60°C as compared to other three temperatures % at 40°C % at 50°C and % at 60°C respectively Copper dissolution was higher at 60°C than at 50 or 40°C
increase the copper 40 Methanesulfonic acid an organic acid was used as an alternative for mineral acid for extraction of copper from 42 However these systems were in general water rich processes In this paper we describe a green solvometallurgical process for the extraction of copper from sulfidic ore minerals
·Owing to the low grade poor endowment and low output of copper and iron ore resources in China domestic copper ore and iron ore are difficult to meet the needs of industrial development which leads to the continuous rise of annual imports of copper ore and iron ore Y Liao et al 2017; Shi et al 2020 In 2021 China imported
·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
·Copper oxide powder is mixed with carbon powder The mixture is heated strongly for a few minutes in a crucible A lid is kept on the crucible to prevent the carbon from reacting with oxygen in
·In the present work the extraction kinetics of copper using the resulting actual leach solution obtained from the leaching of malachite ore in perchloric acid solutions and the stripping kinetics of copper from the loaded organic phase were examined The organic phase was prepared by using Acorga M5640 and kerosene In the extraction process the effects of
·Copper is a metal that is widely used in different applications mainly due to its thermal and electrical conductivities together with its corrosion resistance particularly when it is alloyed This chapter intends to be a summary of the copper metallurgy from the historical aspects and mineral deposits or statistics to the different technologies used to produce
sulfides sulfates oxides or even metallic copper in the system with a suitable combination of temper ature and This feature has been the basis of several studies on copper extraction and 35 For the majority of copper bearing materials where iron is the major metal copper and iron can be converted to copper
An oxidized lateritic ore which contained % by weight copper was bioleached in pH and temperature controlled stirred reactors under acidic reducing conditions using pure and mixed cultures of the acidophilic chemolithotrophic bacterium Acidithiobacillus ferrooxidans Sulfur was provided as th Extraction of copper from an oxidized
·Extraction of copper ore Extracting copper ore is a labor intensive process that requires various stages and special equipment The process begins with blasting where explosives are used to break apart the ore so it can later be loaded into trucks and sent to crushing facilities Crushing reduces the ore to fragments small enough for further
·The copper extraction in shaking bioreactors was modeled and optimized using response surface methodology RSM Influential parameters in the mesophilic bioleaching process of a low grade copper ore including pH value pulp density and initial concentration of ferrous ions were comprehensively studied
Instead the usual ore of aluminum is bauxite which contains from 50 70% of aluminum oxide Copper is much rarer but fortunately can be found in high grade ores ones containing a high percentage of copper in particular places Because copper is a valuable metal it is also worth extracting it from low grade ores as well
·In the present case the dissolution behaviour of copper and cobalt from Cu Co oxidized ore using synthetic organic acids independent of microorganisms was studied The effect of leaching
·The copper concentrate obtained from the flotation of tailings [30] was used as feed sample in this achieve an excellent copper dissolution from the concentrate of flotation tailings which consist of chalcopyrite as the major copper component high‒pressure leaching HPL was conducted using an autoclave under a variety of sulfuric acid
·The effect of time on the leaching of copper oxide ore was investigated at room temperature in the range of 15 240 min The results are shown in Fig 1 which indicates that the increase of time on the dissolution of copper oxide ore produced an increase in the dissolution of copper cobalt and iron However it was noticed that the copper
·Currently approximately 60% nickel is extracted from nickel sulfide ore but in recent years high grade nickel sulfide ore is gradually exhausted due to the overexploitation and the low grade ore that is difficult to process has become the main raw material for nickel extraction Chen et al 2017 Chen et al 2018 Guo et al 2009 He et
·The main difficulty in sorting copper bearing pyrite is that this type of ore has high sulfur content and is very easy to oxidize During the oxidation process the primary chalcopyrite in the ore may form three types of substances secondary copper sulfide chalcocite and digenite water soluble copper chalcanthite and pisanite and malachite and azurite
