Copper Mining and Processing: Processing Copper Ores

Although the processing costs are higher, ultimately more copper can be extracted. Since each mine site is unique in its Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. Copper extraction

During the extraction of copper from chalcopyrite ore, the ore ( CuX2S⋅FeX2SX3 C u X 2 S ⋅ F e X 2 S X 3) is heated to form CuX2S C u X 2 S and FeS F e S. Then during smelting it reacts with OX2 O X 2 to form CuX2O C u X 2 O . Then it is written that CuX2O C u X 2 O reacts with FeS F e S to form CuX2S C u X 2 S.inorganic chemistry Extraction of copper from chalcopyrite

Copper leaching from primary sulfides: Options for biological and

The primary sulfide minerals of copper have been difficult to leach for the purpose of direct copper extraction. In particular, chalcopyrite has been observed to undergo a type of “passivation” under a variety of oxidative leaching conditions. Over the last 10–15 years, a variety of biological and chemical leaching processes have emerged for The added operating cost of the 1x2x1 circuit is all due to organic losses. If a loss of 50 ppm instead of 100 ppm is assumed, an assumption very much in line with several recently completed plants, then the difference in operating cost is 1.19 cents/lb Cu ($260,610/year). Now the decision is a very difficult one.SX EW Capital & Operating Cost of Solvent Extraction & Electrowinning

Extraction of Copper: Detailed Process The Chemistry Notes

Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.However, the low extraction ability of copper (12 g/l) and high ammonia loading of it led to further studies of new extraction agents from the ammoniacal solutions . These efforts led to synthesis of P204 (D-2-ethyl hexyl phosphate), which is an organophosphorous acid extractor.Ammonia Leaching: A New Approach of Copper Industry in

Removal of Copper Ions from Aqueous Solution Using Liquid Surfactant

Stirring speed was found to be another parameter affecting extraction to a large extent, and it was studied using LSM1 in the 150 to 550 rpm range and shown in Figure 5. Using LSM, as the stirring speed increased from 150 to 250 rpm, copper removal increased from 82% to 94.7% in 11 minutes.To top it all, the national office for the general water managements (DGA) predicts a sharp increase around 4.5% in consumptive demand for water by 2030 (Dirección General de Aguas, 2017).Regarding the copper mining industry, an increase in water consumption of about 25 m 3 s −1 is forecast in the coming decade, mainly as a Membrane technology for a sustainable copper mining industry:

Liquid–liquid extraction

Solvent extraction. Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.Energy and materials flows in the copper industry OSTI.GOV
