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 material was tossed ...

After the gold ore has been removed from the earth using mining equipment, it is sent to a gold processing plant. The typical gold processing plant begins with a cone crusher, to reduce the particle size of the ore. Next, it is loaded on a conveyor belt, where an overbelt magnet removes tramp metal from the gold mining process.
