Gold processingMining and concentrating Britannica
Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.

Using Ball Mills to Extract Raw Gold from Ores
The ore is sent into a single cylinder hydraulic cone crusher for the secondary crushing Thereafter the gold ore is transferred to a multi cylinder 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.

Principals of gold Stamp Mill operations
Principles of Stamp Mill Crushing The most effective method of crushing is by impact but as a particle of ore becomes finer it becomes increasingly harder to catch it fairly between two surfaces so that it may be further crushed or comminuted It is largely because of this that very fine crushing becomes difficult in the stamp battery.
