研究了哈萨克斯坦某矿床低品位铜矿石浸出工艺的主要参数。在选择优化浸出制度时研究了溶浸液浓度、布液密度、布液间歇时间这三个因素的影响。经矿物分析证实,氧化带的基本矿物是硅孔雀石,从浸出工艺观点来看,这种矿物具有耐溶特性。此外,矿石内含有20%的黄铜矿,这增加了从矿石中浸出铜的难度。在没有催化剂的情况下单用硫酸溶液浸出时,浸出率不高。氯化钠可作为浸出的催化剂(苏联发明证书1178784号),故决定采用这种催化剂,并按作者拟定的方法加入。矿石装堆以前先行破碎,然后进行筛分分析,证实原矿粒级为50毫米到+15毫米。浸出法的实
The main parameters of low grade copper ore leaching process in a deposit in Kazakhstan were studied. In the choice of optimal leaching system, the effects of three factors, the concentration of solution, the density of fabric and the intermittent time of fabric, were studied. Mineral analysis confirmed that the basic mineral oxidation zone is silicon malachite, from the leaching process point of view, this mineral has a solvent-resistant properties. In addition, the ore contains 20% chalcopyrite, which increases the difficulty of leaching copper from the ore. In the absence of a catalyst alone with sulfuric acid solution leaching, the leaching rate is not high. Sodium chloride can be used as leaching catalyst (Soviet Union invention certificate No. 1178784), so the decision to use this catalyst, and according to the author’s proposed method to join. The ore was crushed prior to being palletized and then subjected to a sieve analysis to confirm that the ore grade was 50 mm to +15 mm. Leaching method of the real
