May 31, 2016· The g contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The g is within the sulfide mineral matrix, which is not exposed (and therefore can not be dissolved by) a cyanide leach solution. Also the ore contains carbonaceous matter which absorbs g in the conventional leaching process.
