摘要：To design heap biooxidation process,it is necessary to understand its internal *** heap biooxidation of gold ore from Anhui province was researched in this *** results showed that the main microorganisms in the heap were ***,*** and *** their combined action,gold leaching extent rose from 35.62%to 78.08%in 80 *** model matches the actual oxidation effect better and the model equations were *** 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 *** is more reliable to predict gold leaching extent by sulfur oxidation *** results provided good guidance for practical application in the actual production.
