The study evaluated the milling kinetics of three copper ores, from a multi-mineralised deposit, which were identified as sulphide 1 (with bornite as a dominant copper mineral), sulphide 2 (mainly composed of chalcopyrite) and oxide (with malachite as a dominant copper mineral) and related the breakage parameters to the mineral composition data. Five mono-size fractions

Copper Production: How Is Copper Made?

26.09.2019In-situ leaching has also been used to recover copper from suitable areas of ore deposits. This process involves drilling boreholes and pumping a leachate solution - usually sulfuric or hydrochloric acid - into the ore body. The leachate dissolves copper minerals before it is recovered via a second borehole.
