the process comprising the steps of:obtaining a starting material that comprises coal; subjecting the starting material to at least one fine grinding stage so as to reduce the starting material to a particulate composition in which substantially all of the particles are no more than 500 microns (µm) in diameter; exposing the particulate composition to at least one froth flotation stage so as to separate

gold recovery and refining. companies need successful recovery methods that drive profits. design teams with extensive experience in cyanide-in-leach (cil), cyanide-in-pulp (cip), carbon elution, carbon activation— in addition to newer thiosulfate leaching and regeneration processes—can enhance gold recovery and profitability.
particles resulted from such fine grinding are often in order of less than 38 μ m and recovery of these particles is generally low in conventional flotation cells.

just as the size of blasted material affects crushing and grinding, the particle size that grinding produces strongly affects recovery in the separation processes. so, it is important to understand the trade-off between producing a finer grind size (at higher cost and energy consumption and possibly lower throughput) versus the improved liberation and recovery that this generates.
