To design heap biooxidation process, it is necessary to understand its internal rules. The heap biooxidation of gold ore from Anhui province was researched in this study. The results showed that the main microorganisms in the heap were A. ferrooxidans, F. acidiphilum and L. ferrodiazotrophum. Under their combined action, gold leaching extent rose from 35.62% to 78.08% in 80 d. Boltzmann model matches the actual oxidation effect better and the model equations were obtained. The model predicted that the oxidation extents of arsenic and sulfur are 58.577% and 42.122% after one year, and the gold leaching extent was 80.40%. The arsenic and sulfur oxidation extents, and gold leaching extent were all linearly correlated. It is more reliable to predict gold leaching extent by sulfur oxidation extent. These results provided good guidance for practical application in the actual production.

要设计堆生物氧化过程，有必要了解其内部规则。本研究对安徽省金矿的堆生物氧化进行了研究。结果表明，堆肥中的主要微生物为A. ferrooxidans，F. acidiphilum和L. ferrodiazotrophum。。在他们的共同作用下，金浸出程度在80天内从35.62％上升到78.08％。玻尔兹曼模型更好地匹配了实际的氧化效果，并得到了模型方程。该模型预测一年后砷和硫的氧化程度分别为58.577％和42.122％，金的浸出程度为80.40％。砷和硫的氧化程度和金的浸出程度均呈线性相关。通过硫的氧化程度预测金的浸出程度更为可靠。这些结果为实际生产中的实际应用提供了很好的指导。
