The ball mill is designed as a sealed structure specially for batch leaching. The materials, cyanide, water and grinding balls are fed into the ball mill arbitrarily as required. The ball mill is equipped with a special inflatable tube which periodically supply air into the drum of the ball mill during grinding to keep enough oxygen content in the grinding drum for ensuring that gold exposed during grinding reacts with cyanide in

2018-9-29 It is well known that cyanide leaching of gold–silver ore has been an accepted process in the world. In the current study, UFG was proposed as a pretreatment method prior to cyanide leaching of a gold–silver ore. First, the ore was crushed and ground by jaw, cone crusher, and ring mill, respectively.

2009-10-1 Each subsample of 2 kg was used for a mill-leaching test. Sodium cyanide was added into the mill together with water, ore, lime (pH 10.5) and rods. The grinding time was fixed to 2 h reaching a P80 of 0.105 mm, when the rods were removed and activated carbon was introduced to the mill inside a nylon basket. The mill was restarted and the ...

2016-6-8 The ball mill, in closed circuit with a classifier, is fed with ore, cyanide, lime, and carbon as charcoal. The classifier overflow is thickened and then agitated. The gold is dissolved by the cyanide solution and then its soluble gold-cyanide compound is absorbed by the finely divided charcoal.

1996-8-1 Leaching of gold and silver from the Miller Process dross was investigated using non-cyanide leachants. The dross was found to be very refractory to direct leaching with thiourea as well as thiosulphate. Thiourea leaching of the calcined dross resulted in about 84% extraction of gold, but the leaching of silver was very poor.

2015-2-28 According to Deschenes et al. (Deschenes et al., 2003), the minimum oxygen concentration [O2] inside a ball mill has to be at least six times larger than the concentration of cyanide [CN]. The free space in the mill is suf?cient to assure O2 supply, and over the course of the leaching process the mill is frequently stopped for analysis of pH and [CN], which allows air replenishing.
