    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 continuingBall mills in all ore dressing and milling operations, including flotation, cyanidation, gravity concentration, and amalgamation, the working principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals in the chemical and process industries, grinding is an important step in preparing raw materials for subsequentOre Dressing Regrind Ball Mill nhiindiainternationalAmalgamation, followed by cyanidation, has been observed at many artisanal mining sites This combination poses additional environmental and health consequences Tests with ore samples from Talawaan, North Sulawesi, Indonesia indicate the possibility of replacing mercury by cyanidation in the ball mill, reaching gold extraction of 93% in 6 h ofMill Leaching: a viable substitute for mercury
