particle size range gold ore

Gold Extraction and Recovery Processes - Semantic Scholar

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

- Particle Size: The cyanidation method is used for particle size range smaller than 200 microns (Mitchell, C.J., 1997). The gold dissolution rate will be increased by decreasing the particle size because by decreasing particle size, particle contact area between solid and liquid phase will be increased and this will increase the dissolution rate

The ore is crushed and milled together with water in tuling mills, so called ball mills, where the balls have been replaced by iron rods in an iron drum (about 2 m60.5 m), and rotated by an electrical motor (2.5–3 Hp per drum). After 6–10 h of milling, the particle size is smaller than 0.35 mm and about 60% smaller than 0.2mm(seeFig.2).
