Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore. While chalcopyrite remains refractory to ambient temperature bioleaching, other copper sulfide minerals - the secondary sulfide minerals - such as chalcocite, covellite, bornite, etc. - are leachable by today's technology.

In situ leach - Wikipedia

In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
