中文摘要: 对元江铁质和镁质红土镍矿进行加压浸出试验，详细考察了浸出温度、反应时间和初始酸度对镍浸出率及酸耗的影响。结果表明，铁质矿的镍浸出率可达90%以上，吨镍酸耗可降低至45 t以下；镁质矿的镍浸出率可达80%，吨镍酸耗70 t左右。采用两段加压浸出工艺处理该红土矿，镍浸出率可达88%以上，吨镍酸耗50 t左右。
Abstract:Pressure leaching experiments were conducted on ferruginous and magnesium laterite-nickel ore. The effects of leaching temperature, time and initial acidity on nickel leaching rate and acidic consumption were investigated in detail. The results show that the nickel leaching rates of ferruginous minerals and magnesium minerals are over 90% and 80% respectively. The acidic consumptions of per ton nickel of ferruginous minerals and magnesium minerals are 45 t and 70 t respectively. Nickel leaching rate can reach 88% or higher and acidic consumption of per ton nickel is about 50 t with application of two-stage pressure leaching process.
