particularly challenging for Chile since mining is the most important economic activity in the country [44]. Lagos et al. [5] have recently projected that, from 2030, copper production in Chile will decrease due to the lack of technologies that would make the extraction of low-grade ores feasible.from copper cathode, various metals, metal sulfates or clinkers, as well as sulphuric acid, sulphuric dioxide and iron sand.

Copper Mining Extraction Process Flow Chart This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).resource for the copper mining industry, is used in many stages of the mining process [21]. Based on projections, total water consumption for copper mining in Chile will be 23.3 (m3/s) by 2031, representing an annual average increment of 2.1% [22]. The increase in water consumption is due to two main reasons. The first is a changeEnvironmental Management Strategies in the Copper

Chile is the world’s largest copper producer, accounting for 27% of total global output. By refined copper production, which includes both copper anodes and scrap metal, China is the leader, accounting for 36% of total world refining.

The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal.
