摘要： A heap bioleaching process wherein carbon, in the form of a carbonate, carbon dioxide or organic carbon, is added to the heap when the temperature in the heap is in the range of 45oC to 60oC to increase microbial activity and thereby raise the heap temperature to above 60oC.

摘要： A method for optimizing a bioleaching process, at least in respect of heat generation and primary copper sulphide leaching, by actively monitoring and controlling inorganic and organic compounds in a raffinate solution, produced in the process, to levels below that which could be inhibitory to microbial activity of bioleaching strains used in the process.
