中文摘要: 采用低酸高温氧压浸出工艺从硫化镍精矿中提取镍，考察硫酸起始浓度、氧分压、浸出温度、时间和液固比对镍浸出率的影响。结果表明，在下述最佳条件下镍浸出率可以达到95%：起始酸度50 g/L，氧分压0.9~1.0 MPa，温度130~150 ℃，时间6 h，液固比5∶1。
Abstract:Nickel was extracted from nickel sulfide concentrate through oxidation leaching process with low acid concentration and high temperature. The effects of initial vitriol concentration, oxygen partial pressure, temperature, time and ratio of liquid to solid on the leaching rate of nickel were investigated. The results show that the leaching rate of nickel will reach 95% under the following optimum conditions including initial acidity of 50 g/L, oxygen partial pressure of 0.9~1.0 MPa, temperature of 130~150 ℃, time of 6 hours, and ratio of liquid to solid of 5∶1.
