Thus, ore dust containing gold is lost to the environment during milling and unloading of the mill. Wet milling is normally used in direct smelting, but in this experiment dry milling was used for both methods for a thorough comparison. Dry milling likely resulted in a loss of a small amount of gold and thus biased the results in favor of the ...

The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.

This type of SSGM involves several subprocesses: (1) tunneling, (2) ball milling and gravity concentration, (3) cyanide leaching, and (4) smelting. First, tunneling involves digging a pathway or tunnel into the rock or earth under which the gold ore is believed to be located. The gold ore usually runs through the earth in veinlike formations.
