Using Mercury in Gold Ore Crushing
The earliest machines used for the purpose seem to have been stone mortars, in which the gold quartz was crushed by stone-hammers, or by large rocks raised by levers and let fall, whilst the fine material was subsequently washed out with water.The heavy particles of gold then settled to the bottom of the mortar, the lighter worthless material being washed away.
