The gold ore is pyrite wrapped microscopic gold sub-microscopic gold or solid solution of gold-bearing ore, is the the insoluble extraction of gold gold ore. The key of the gold extraction of mineral processing equipment destruction pyrite wrapped gold full dissociation.C&M Mining Machinery in South Africa by ultrafine grinding process calcine after roasting arsenopyrite and pyrite flotation concentrate Sec boiling. Domestic researchers have also done a lot of work to prove that low-speed stirring mill, vertical screw stirring mill grinding equipment even more superior. Low energy consumption, high grinding efficiency and the gold recovery slaughter high.
Another vertical screw Family stirring mill (tower mill) strong in process of edging Baptist, grinding media and mineral aggregate peel grinding, destruction of the surface of the material particles diffuse interface layer, thus speeding up chemical reactionsspeed. In process of edging Baptist, finely ground particles constantly exposed fresh, highly active reaction surface, too late passivation on to participate in the leaching reaction, which can not only accelerate chemical reactions, but also improve the chemical leaching rate, increase the gold ore beneficiation efficiency.
Ultra Fine Grinding For Gold Ore
Ultra fine grinding mill is essential to the Albion Process, as it increases the surface area of the sulphide particles enhancing the rate of downstream chemical reactions as well as distorting the minerals crystal lattice, lowering the required activation energy for the chemical reaction to follow.Ultra fine grinding is achieved through the use of an Mill, a patented horizontally stirred mill that uses a series of rotating disks inside a stationary shell to stir small ceramic beads. The ceramic beads impart energy to the sulphide particles resulting in an ultra fine grind. The ceramic beads are inert and have no impact on the chemistry of the slurry as they break down over time in the Mill.
There are in excess of 70 Mills installed worldwide at present, with more installed power (+200MW) than all other commercial ultrafine grinding mills combined. Laboratory scal mills are able to determine grind characteristics and power draws for concentrates with high levels of accuracy resulting in minimal scale up risk to the commercial IsaMills.
