| Abstract: | A gold ore containing arsenic, clay and carbon which can adsorb dissolved gold, in Yunnan province, is researched. Gold hosts in ultramicro form in other minerals, and the ore belongs to carlin type. The direct cyanide leaching rate of gold is 3.17 % -4.7 %. With 6 months＇ pretreatment of heap leaching biological oxidation, the leaching rate of gold can reach 65.5 %. |
