摘　　要：叙述了生物浸出法去除伊利石中铁的试验过程。结果表明,在-12.5mm粒度条件下,含铁为1.57%的伊利石经过170天生物氧化,铁含量降低到0.36%,最高铁浸出率达到了76.9%,其白度由原来的60.5%提高到86%。The process of biology leaching to remove iron from illite was described. The results showed that the iron content of illite, which particle size was less than 12.5 mm, decreased from 1.57% to 0.36% after 170 days of bio-oxidation. The highest leaching rate of iron reached to 76.9%. The whiteness of illite increased from the original 60.5% to 86%.
