Effect of Particle Size and Grinding Time on Gold Dissolution
The recovery of gold by ore leaching is influenced by the size of the particles and the chemical environment. The effect of particle size on the dissolution of gold is usually studied using mono-size particles as the gold in solution comes from the ore of a unique leached particle size. This paper proposes a method to estimate the gold Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses Comminution circuits for gold ore processing ScienceDirect

F. Nava-Alonso. E.T. Pecina-Treviño. This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size ofThe oxidation roasting of carbon-bearing micro-fine gold can eliminate or weaken the robbing effect of carbonaceous materials and clay, and destroy the encapsulation of micro-fine gold. The micropores produced by gas escaping during the roasting process are conducive to the diffusion of leaching agents, thus enhancing the Oxidation Roasting of Fine-Grained Carbonaceous Gold Ore:

Ultra Fine Grinding A Practical Alternative to Oxidative
Along with the determination of the grind/recovery curve, a mineralogical assessment of the gold deportment and particle size may provide additional information. Mineralogical scans such as QEMScan and MLA are able to give good data as to the mineral liberation and particle size of gold down to about 5µm. Below this size, an screened and analyzed for gold by particle size class. The progressive grind approach limits the smearing of gold particles and allows for the recovery of GRG as it is liberated. The results from the test are presented as a cumulative GRG distribution as ell as GRG distribution by particle size class as shown In Figure 2.
