The original gold winnowing process was a dry separation technique, accomplished by wrapping sandy gold ore in a woolen blanket, which was then shaken up and down by two men (Wilson, 1961). In the process, the gold particles were triboelectrically charged and attached to the blanket. Then, the blanket was opened, and …
The gold contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The gold 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 gold in the conventional leaching process.
