grinding process in gold making

First a solution carries the ground ore over plates covered with mercury The mercury attracts the gold forming an alloy called an amalgam The amalgam is then heated causing the mercury to boil off as a gas and leaving behind the gold The mercury is collected recycled and used again in the same process

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
