新疆哈密某矿难选金矿选矿方法试验结果
1、针对矿石特征，借鉴以往的选矿经验，采取“原矿破碎-预浸(碱浸、氨浸)－洗涤(铜液和洗液单独存待放回收铜)－氰化－活性碳吸附”工艺流程，消除或减弱了有害物质的影响，取得了较好的选矿指标。
2、氨预浸要“短、平、快”，pH值及氨浓度不宜过高，以避免已氨浸出的[Cu(NH3)4]2＋发生变化的可能及碳铵、碱的过多消耗或浪费。
3、若进行半工业试验，筑堆时可增加自然通风设施。同时，应开展进一步的试验与研究，以求早日应用于生产。

1, according to the characteristics of ore dressing, from past experience, take the "ore crushing - prepreg (alkali leaching, ammonia leaching) - (washing liquid copper and lotion alone to be put in the recovery of copper deposit) - cyanidation activated carbon adsorption process, eliminate or weaken the influence of harmful substances, has good processing index the.
2、氨预浸要“短、平、快”，pH值及氨浓度不宜过高，以避免已氨浸出的[Cu(NH3)4]2＋发生变化的可能及碳铵、碱的过多消耗或浪费。
2, ammonia to prepreg "short, flat, fast, pH value and ammonia concentration should not be too high, in order to avoid has ammonia leaching of [Cu (NH3) 4]2 + and ammonium bicarbonate, alkali change excessive consumption or waste.
3、若进行半工业试验，筑堆时可增加自然通风设施。同时，应开展进一步的试验与研究，以求早日应用于生产。
3, if the semi industrial test, to build a pile of natural ventilation facilities can be increased. At the same time, further experiment and research should be carried out in order to be applied in production at an early date.
