| 摘 要： | 本文以金川铜镍硫化物精矿为研究对象,对比研究了A.f.菌浸出与硫酸酸溶浸出对铜镍硫化物精矿中有价金属Co、Ni和Cu的提取效果。为了进一步优化硫化物精矿中有价金属Co、Ni和Cu浸出效果,考察了微生物-硫酸浸出与硫酸-微生物浸出对精矿中Co、Ni和Cu提取的影响。结果表明:Co2+、Ni2+、Cu2+微生物-硫酸浸出率可分别达到85.05%、98.32%和95.31%。微生物-硫酸浸出加速了硫化物矿物的溶解,促进了硫化物矿物中有价金属Co、Ni、Cu的浸出,大大提高了有价金属Co2+、Ni2+、Cu2+的浸出率。

| Abstract: | In this paper, the Jinchuan copper-nickel sulfide flotation concentrates were studied to compare the Co, Ni and Cu extraction results of sulfuric acid leaching process and A.f. leaching process. Further enhancement of metals leaching rates was achieved by bio-chemical leaching and chemical-bioleaching. The results showed that the bio-chemical leaching rates of Co2+, Ni2+ and Cu2+ reached 85.05%,98.32% and 95.31%, respectively. The combination of first bioleaching process and the following chemical acid leaching process facilitated the dissolution of the sulfide and strengthened the leaching effects of Co2+, Ni2+ and Cu2+ from complex sulfide concentrate. |
