Jun 14, 2018#0183;#32;The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder 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.
Abstract. Artisanal smallscale gold miners (ASM) occasionally employ whole ore amalgamation by adding mercury into ball mills to recover gold. In this process, 2530% of the mercury added is lost to the environment. It is also inefficient less than 30% of gold is recovered. Amalgamation, followed by cyanidation, has been observed at many artisanal mining sites.
Apr 08, 2014#0183;#32;A teenage boy works in a ball mill beneath a house in Diwalwal. Mercury is added directly to the ore in the iron cylinders to make the gold extraction process more efficient. Mercury particulate is released as the ball mills are flushed. Image by Larry C. Price. Philippines, 2013.
