Advantages of gold ore processing mill types

extracting gold howstuffworksat a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. the gravel like material then enters rotating drums filled with steel balls. in these drums, the ore is ground to a fine slurry or powder. next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. leaching dissolves the gold out of the ore using a chemical solvent.
