| 摘 要： | 采用经过驯化的HQ0211菌对高砷金矿进行氧化预处理-氰化提金实验研究.该矿石含金128.5 g/t,含砷16.84%(质量分数,余同),含硫21.72%,含铁26.62%,氰化浸出率只有29.35%,是典型的高砷难处理矿.经过细菌氧化预处理,金矿脱砷率达到96.2%,失重率达到43.9%.矿石的金氰化浸出率由原来的29.35%提高到92.57%,效果十分显著.

| Abstract: | The experiments of bacterial oxidation,cyanidation extraction gold from refractory high arsenic gold ore were carried out with bacteria HQ0211 domesticated.This kind of gold ore contains 128.5 g/t gold,16.84% arsenic,21.72% sulfur,26.62% iron.The leaching rate of cyanidation only has 29.35%.It is classed into the high arsenic refractory gold ore.The dearsenication rate of the gold ore is 96.2%,weight-loss rate is 43.9% through bacterial oxidation pretreatment.After bacterial oxidation,the gold cyanidation l... |
