dc.description.abstract为了探索黄铜矿低温常压湿法氧化(O2)浸出的可行性,研究了黄铜矿在酸性介质中的溶解行为,考察了温度、酸浓度及溶浸时间等对黄铜矿酸浸行为的影响,计算了酸浸过程中铜的浸出率,分析了元素硫的变化行为及残渣微观结构。结果表明,黄铜矿常压湿法氧化(O2)浸出过程的酸浸阶段会产生硫化氢;黄铜矿的溶解能力随温度变化先快后慢,后段接近线性增长,溶解主要发生在前2小时;低温有利于溶解,而最适酸浸pH约-0.4。pH对溶解的影响小于温度的影响。
dc.description.abstractThe dissolvability behaviors of chalcopyrite in acid solvent,including the influences of temperature,pH value and the acidic leaching time on the dissolvability behaviors of chalcopyrite,are studied to probe the feasibility of hydro-oxidation leaching at normal pressure and low-temperature.The changing behaviors of elemental sulfur and the microstructure of the residue are also analyzed.The results show that:①sulfureted hydrogen can be produced in the acidic leaching of chalcopyrite's wet oxidation at ordinary pressure and low-temperature;②the dissolvable capacity of chalcopyrite change with time fleetly at first then slowly,which is linear increase at the later part,the dissolution occurs mostly at 2 hours afore;③low temperature is beneficial to the dissolution and the optimum pH value is-0.4.And the influence of temperature is stronger than that of pH.
