摘要:

以甘肃某含硫、砷、碳及锑等多种成分的难处理金矿为研究对象,开展了细菌氧化—氰化实验研究。浸矿菌种为HQ0211,该菌种经长期驯化,耐砷性良好。在浸出过程中,通过测量矿浆的pH 值、电位值、Fe2+质量浓度和液砷含量,来考察不同矿浆浓度对浸出效果的影响。实验结果表明:HQ0211混合菌种适宜氧化该复杂难处理金矿。经该菌种氧化预处理后,脱硫率最高可达81.53%,脱砷率最高可达86.88%,脱碳率最高可达58.32%,脱锑率最高可达40.09%。与未经处理的原矿氰化提金结果相比,经过细菌氧化预处理后,金的回收率最高可达98.65%,相比直接氰化浸出提高了40.56%。

关键词: 复杂难处理金矿, 细菌氧化, 氰化提金, 浸矿菌种HQ0211, 脱硫, 脱砷, 脱碳, 脱锑

Abstract:

Taking the complex refractory gold mine containing sulfur,arsenic,carbon and antimony in Gansu Province as the research object,we carried out bacterial oxidation-cyanidation experiment.Bacteria used in the leaching was HQ0211 which was a kind of mixed bacteria being able to grow normally in the system containing arsenic after a long time of domestication.During leaching of the concentrate,the effects of different pulp densities on bacterial oxidation were evaluated by measuring the pH value of solution,the electric potential value of solution,the density of Fe2+,the density of arsenic in solution.The results indicated that the mixed bacteria cultures HQ0211 showed good biooxidation performance for the complex refractory gold concentrate. After biooxidation,the maximum sulfur removal efficiency of 81.53%,arsenic removal efficiency of 86.88%,carbon removal efficiency of 58.32% and antimony removal efficiency of 40.56% were achieved in the presence of the HQ0211 mixed culture.Highest gold recovery of 98.65% was achieved by cyanidation after biooxidation,which increased by 40.56% comparing to the result from cyanidation of the untreated concentrate.

Key words: complex refractory gold concentrate, bacterial oxidation, cyanidation, bioleaching bacteria HQ0211, sulfur removal efficiency, arsenic removal efficiency, carbon removal efficiency, antimony removal efficiency
