摘要: 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.

摘要: A method of processing a pyrite-containing slurry is disclosed. The method includes removing pyrite from the pyrite-containing slurry and forming (i) an inert stream and (ii) a pyrite-containing material, with the pyrite-containing slurry including tailings from a tailings dam or an ore processing plant. The method also includes leaching a metal sulfide-containing material and the pyrite-containing material with a leach liquor and microbes. A method of leaching 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.

摘要: A method of heap leaching a metal from a mined ore that contains a metal sulfide-containing material, such as a copper sulfide-containing mineral. The method forms a heap of the mined ore or extends an existing heap by adding the mined ore to the heap. The method also leaches the metal from the mined ore in the heap with an acidic leach liquor and produces a pregnant leach liquor containing the metal in solution. Pyrite that is already in the mined ore generates acid and heat that facilitates leaching metal from the mined ore. The mined ore may be run-of-mine (ROM) ore that is transferred directly from the mine to the heap without changing the size of ore particles in the mined ore.

摘要: A method of processing a pyrite-containing slurry including removing pyrite from the pyrite-containing slurry and forming (i) an inert stream and (ii) a pyrite-containing material. Using the pyrite-containing material in a downstream leach step in which pyrite in the pyrite-containing material generates acid and heat that facilitates leaching a metal, such as copper or nickel or zinc or cobalt, from a metal-containing material.
