Abstract. Beneficiation of chalcopyrite and most minerals in general requires specific conditions and raw materials based on characteristics of the mineral to optimize processing hence income. Therefore characterization of minerals is an important aspect in mineral processing. In this investigation X-ray diffraction (XRD) and Scanning ...

Mining-process waters become saturated with soluble salts after contact with minerals (oxidation and dissolution) during crushing, classification and flotation. Inorganic species, such as metal ions but also carbonate and sulphate ions, may have a positive or negative effect on mineral flotation. ... For chalcopyrite, the presence of Cu ...

Table 1 lists a selection of studies in which chalcopyrite bioleaching with chloride ions was investigated along with the highest copper extraction achieved in these studies. Chang-Li et al. (2012) reported high copper recoveries by using the thermophilic archaea Acidianus manzaensis, when bioleaching a chalcopyrite concentrate, at 65 °C …

The current representative chalcopyrite bioleaching process is the BioCOP™ process developed by BHP Billiton . When chalcopyrite is leached with …

Chalcopyrite is the most abundant copper ores in nature and the main source of copper resources. Low energy consumption but slow kinetics occurred in the microbial fuel cell (MFC)-assisted chalcopyrite bioleaching process. High price and low recovery limited the use of silver-bearing chemicals as catalysts for the chalcopyrite bioleaching.

The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.Higher …

Bio-mining, also known as bio-leaching, employs various micro-organisms for the processing of metal-containing ores and concentrates (Brierley, 2008;Rawlings et al, 2007). Micro-organisms such as ...

The post-treatment, including neutralization and coagulation process, was found efficient for the reuse of ED treated chalcopyrite mining wastewater in the industry. As mentioned before, due to the high level of acidity level and high amount of neutralizing chemicals of (NaOH and Ca(OH)2), the treatment cost of wastewater in the chalcopyrite ...

Jetti Resources, a start-up founded in 2014, says its technology makes it possible to extract copper from low-grade primary sulfides like chalcopyrite, the world's most abundant copper mineral ore.

The main challenge for chalcopyrite processing is the formation of a metal-deficient sulfide (i.e. sulfur enriched) layer, which greatly inhibits leaching kinetics. ... Future of mining, mineral processing and metal extraction industry. Trans Indian Inst Met, 72 (2019), pp. 2159-2177.
