The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome inCopper 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 Potential environmental pollution from copper metallurgy

Sensor-based ore sorting is a method that involves identifying and discarding waste or uneconomic material using the information obtained by sensor technologies to improve the quality ofCopper output and price movements in Zambia’s mining history [9]. Biohydrometallurgy is essentially the application of biotechnology to processing minerals [8, 10]. Technically, the process is a branch of hydrometallurgy, but it involves the use of microorganisms to biooxidise sulphide minerals ore from low-grade copper ore deposits [11].Application of Biohydrometallurgy to Copper Mining in

In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia []) owing to the exhaustion of rich copper resources.The flowsheet of processing copper ores is developed for each If we consider only the top 20 copper mines with the most important reserves of copper (over 1,000 million tonnes of copper reserves) the average copper ore grade of this group is only 0.76% copper, including deposits with a high average copper ore grade, such as Tenke Fungurume with 2.32%Cu, Resolution with 1.5%Cu, Taimyr Processing of Complex Materials in the Copper Industry:
