摘要
研究氧化型碳质金矿的氰化行为及其中碳质物对金的吸附能力，探讨某些有机化合物对碳质物和活性炭吸附能力的抑制或促进。结果表明，某些芳烃衍生物可使碳质物的吸金量和吸附速度降低７５％，某些胺类化合物能提高活性炭的吸金能力，两者以适当方式加入矿浆可以使金的收率从８３．３％提高到９５．６％。
In this paper,the behaviors of oxygenated carbonaceous gold ore in the course of CIL and the gold adsorptive capacity of carbonic component in such kind ores are investigated. Inquisions on promoting or inhibiting adsorptive capaicty of carbonaceous matters and activated carbon by some organic compounds are made too.It demonstrates that the gold adsorphion velocity and quantity of carbonaceous matters can be decreased by 75% by aiding some kinds of aromatic hydrocarbon derivatives while the gold adsorptive capacity of activated carbon can be increased by aiding some kinds of ammes.The gold recovery can be increased from 83.3% to 95.6% by aiding both above organic compounds in proper way.
