Beschreibung
Zusammenfassung:	A method of recovering a metal, such as copper or nickel or zinc or cobalt, from a metal sulfide-containing material in a mined material that is "non-economic" to recover metals from using conventional recovery options before the invention was made is disclosed. The method includes mixing (i) the metal sulfide-containing material and (ii) pyrite and forming agglomerates, leaching agglomerates with a leach liquor and microbes and removing a metal from the metal sulfide-containing material and forming a pregnant leach liquor containing metal, and recovering the metal from the pregnant leach liquor. A heap leaching operation for a metal sulfide-containing material is also disclosed. A flotation circuit for an ore processing plant for a metal sulfide-containing material is also disclosed.
