在半工业试验中,细菌氧化法已成功地处理了难浸金精矿。试验证明,细菌繁殖能够破坏硫化矿的结构而使金浸出。氧化了的精矿用氰化液浸出时,金浸出率可以达到90％以上。 用来分解难浸金精矿的细菌是自然混合培养的,可耐55℃的环境温度,使得该项技术特别适合于澳大利亚和美国北部的一些矿点。在正常情况下,细菌生长得很好,能经受食物和操作条件的变化并取得了令人满意的氧化效果。
In semi-industrial tests, the bacterial oxidation process has been successfully processed refractory gold concentrate. Experiments show that bacterial growth can destroy the structure of sulfide ore leaching gold. Oxidized concentrate with cyanide leaching, the gold leaching rate can reach 90%. The bacteria used to break down refractory gold concentrates are naturally mixed cultures that are resistant to ambient temperatures of 55 ° C making the technology particularly suitable for some of the ore points in Australia and the northern United States. Under normal conditions bacteria grow well and can withstand changes in food and operating conditions and achieve satisfactory oxidation.
