Crushing in Mineral Processing

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-resistant plate/surface. Less abrasive and softer rocks or stones ...

circuit (crushing, stockpiling and grinding) representing 35% and 50% of plant capital cost for the 1 Mt/a and 20 Mt/a plants, respectively. Comminution costs include power, grinding media and maintenance materials. These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the “efficiency” of a modest plant is improved by simplifying the ...

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,

Crushing and Grinding - Gold Companies Explained

Crushing and milling of gold bearing rock is done so that free gold particles can be liberated and collected; and gold dissolving fluids can act on as much surface area as possible to dissolve the maximum amount of gold. How much crushing is needed will depend on the properties of the ore rock (hardness, porosity, brittleness); the nature of the gold within the ore (coarse, fine, stuck to ...

The crushing, grinding and gravity portion of this process is essentially the same as the free-milling process discussed above. Instead of cyanide leaching of the cyclone overflow, the gold and sulfide minerals are recovered by flotation. The particles in the cyclone overflow are mixed with chemical reagents to render the surfaces of the gold-containing sulfide minerals hydrophobic (metallic ...
