The economic advantage arises out of the fact that some cost-intensive process steps necessary in the treatment of high-grade ores can be avoided, primarily comminution through milling to make the ore amenable to subsequent flotation (copper sulphides) or direct leaching (copper oxides, gold ores).

Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.

The method is applicable to a wide range ores with varying mineralogies. Significant variation in the amount of barren rejectable gangue for a given gold ore and a given gold loss to rejects was observed for the various crushing technologies at the same pass size, even though the particle size distributions were fairly similar.

High-pressure oxidation comprises the oxidisation of sulphide/carbonaceous gold ore at high pressure and temperature. Temperatures exceeding 200 °C and oxygen pressures above 2200 kPa are used to attain complete oxidation of the gold-bearing ore. Reaction rates can be very fast, and the technology is widely-accepted.

The gold ore once mined is processed by separating the gold mineral from the crude matter holding it together. The ore is then pulverized using pressure to create very fine particles. The fine particles are then heated in a furnace to temperatures over 1,064 degrees Celsius, which is the melting point of gold.

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …

The crushed ore is transferred to a grinding mill, which contains heavy-duty steel balls or rods. As the mill rotates, the balls or rods crush and grind the ore, resulting in the formation of a fine powder. The purpose of crushing and grinding the gold ore is to liberate the valuable gold particles from the surrounding rock and minerals.

Response: The word "grain" is related to the specific mineral species. For example, a gold-bearing ore particle is composed of many mineral species and gold. The gold particles included in an ore particle are denominated "grains". As such, it would not be appropriate to follow the reviewer´s suggestion.
