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 dissolution as a function of particle size using a bulk ore sample, i.e., with the dissolved gold coming from the various sizes of particles carried by the ore.

Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In ...

In simple ores, the amenability of the composite to the recovery influenced by the gold minerals distribution, gold particle size, degree of oxidation and occurrence. Sometimes, gold deposits are not exploited due to the mineral was not well understood and the process was not able to give high recoveries, or at least, expected recoveries.

The ore is crushed and milled together with water in tumbling mills, so called ball mills, where the balls have been replaced by iron rods in an iron drum (about 2 m60.5 m), and rotated by an electrical motor (2.5–3 Hp per drum).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).

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.
