When the ore has coarse grain dissemination and the gold granularity is larger than 0.2mm, or when the ore is quartziferous gold-bearing mineral without sulfide
Gold ore crushing & processing. 1. Trucks transport the ore from open pits or underground operations to processing operations. 2. Determine the geochemical makeup of the ore, including its hardness, sulfur content, carbon content and other minerals found within, impact the cost and methods used to extract goldFlotation kinetics of a pyritic gold ore ScienceDirect,2011-1-17 · Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant
