Abstract: Microbial-assisted heap leaching of fragments or agglomerates of fragments of copper-containing sulfidic ores, such as chalcopyrite ores, and copper-containing sulfidic waste materials is disclosed. A heap leaching method includes controlling the sulfate concentration in a leach liquor. When heap leaching includes using agglomerates, a method of forming agglomerates includes adding the feed materials at, or close to, the inlet end, typically no more than 40%, typically no more than 30%, more typically no more than 20%, of the length from the inlet end of the agglomeration unit.
