| Abstract: | This paper describes the experimental investigation on the pressure leaching process of middling from floatation process of low-grade nickel sulfide ore.The influence of those factors including dosage of original sulfuric acid, oxygen pressure,leaching temperature,leaching time,stirring velocity and ratio of solid and liquid on nickel leaching rate are investigated.Under the optimum condition,the remained nickel average content in residue is 0.082%,the average leaching rate of nickel is 93.35%. |
