摘要 / Abstract
由于含碳物质（CM）的存在，难浸含碳金矿石在金氰化过程中面临挑战，这些物质会预浸溶解的金，从而 导致回收率降低。在一项正在进行的研究中，这种真菌黄孢原毛平革菌已被用于使 CM 失活，并降低其对金氰菊酯 的预处理能力。据报道，金孢假单胞菌通过表面氧化对 CM 进行生物转化，这会破坏吸附所需的连续石墨结构，并 改变适合吸附金氰化物的孔。目前的研究重点是使用无烟煤作为 CM 的替代品，并建立真菌处理参数，以最大程度 地减少无烟煤级 CM 的预抢劫。结果表明，黄孢假单胞菌可以在多种生长介质中存活，并具有在宽时间、纸浆密度、 温度、pH 和搅拌水平范围内使无烟煤失活的能力。在 pH4 和 37℃下，5-7 天的处理时间是最佳条件。固定培养和摇 动培养的最佳纸浆密度分别为 60% 和 25%。
