Copper extraction Wikipedia

Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). The global copper concentrate marketwas valued at US$81 Billion in 2019 and is projected to reach US$93 Billion by 2027 expanding at a CAGR of 2.5%. The TCs are charged in US$ per tonne of concentrate treated and RCs are charged in cents per pound treated, denominated in US dollars, with benchmark prices set an
