Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.
In CIL (carbon in leach) process, activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in solution. Because the carbon particles are much larger than the ore particles, the coarse carbon can then be separated from the slurry by screening using a wire mesh.
Ball Mill Motor drives the rotary cylinder through the rotation of reducer and surrounding large gear or it directly drives the cylinder with the rotation of surrounding large gear. The body of cylinder has installed appropriate grinding media - grinding mill balls or steel bars. They are raised to a certain height by centrifugal force and friction, and then fall down with the falling down or drain off state. Grinded materials are continuously given to the cylinder from the mouth, and then crushed by the movement of the grinding media. Finally, the materials will be discharged by the strength of overflow and continuous ore feeding so as to move to the next step.
CIL is cyanide gold extraction process. Firstly, raw material is crushed into less than 10mm by different types of crushers; secondly, crushed material will be ground and classified into 90% of 200mesh, then fine powder will get into thickner, after concentration, add chemical and leach in the leaching tank. After leaching, we can use activated carbon to adsorb gold, then get gold loaded carbon. Finally we can use electrolysis equipment or fire to get gold bar.
