gold mining milling process

Amalgamation is accomplished by passing a slurry of ore over copper plates coated withmercury,by mixing a slurry of ore andmercuryin a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebblemillto free thegoldfrom the mineral matrix and then addingmercuryto themilland continuing grinding until thegoldhas dissolved in the mercury.
