摘　　要：简要介绍了国内生物氧化技术在难处理金矿石预处理上的特点,从精矿再磨矿、生物氧化、氧化渣洗涤液中和以及氧化渣氰化提金等作业进行了研究,比较了不同生物氧化厂设计和生产的异同,探讨了应用中可能出现的问题及解决办法。The paper briefly introduces the characteristics of pretreatment of reiractory gold ores using blo-oxldation in China and compares different production operations and designs between bio-oxidation plants based on the analysis of such processes as secondary grinding of concentrates, bio-oxidation, rinsing of oxidation slag, neutralization of oxidized scrubbing solution and cyanide leaching of oxidized slag. Problems likely to occur and corresponding solutions are out forward and explored.
