中文摘要：
采用硫酸作浸出剂，对新疆土屋低品位氧化铜矿进行堆浸工业试验，重点考察了不同粒度和矿堆堆高的渗透性、铜浸出率及酸耗的变化，并探讨了当地气候条件对堆浸的影响。结果表明，-50mm的矿石堆浸60天，铜浸出率可达80％以上。吨矿酸耗和水耗分别为24．2kg和164kg，吨铜酸耗和水耗分别为9．4t和63．9t。该矿采用堆浸一萃取一电积工艺回收铜是可行的。
英文摘要：
The pilot plant test on heap leaching of low grade oxidized copper ore in Tuwu, .Kmjlang u ygnur Autonomous Region was conducted with the use of sulfuric acid as leaching agent. The permeability, copper leaching rate and the consumption of sulfuric acid of different granularity and heap height were investigated; furthermore, the effect of local weather conditions on heap leaching was discussed. The results show that the copper leaching rate is 80% above in view of -50 mm for 60 days sulfuric acid solution spray leaching. The actual consumption of sulfuric acid and water are 24.2 kg and 164 kg per tonnage ore, respectively. The actual consumption of sulfuric acid and water are 9.4 t and 63.9 t per tonnage copper, respectively. It is feasible to recover copper from this low grade oxidized copper ore with the process of heap leaching, solvent extraction, and electrodeposition.
