  • Heap Leaching A Stack Of Gold Miningfeeds

    Apr 25, 2018 Heap leaching occurs after the mining and crushing of low-grade ores, usually in an opencast mine. High-grade ores and ores not amenable to cyanide leaching at coarse particle sizes require further processing to recover the gold values. These processing methods can include further grinding, concentration, pressure oxidation, and roasting, which is used to treat these ores to expose
