Abstract
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.
