Sampling of the Mine Workings

Situations when mine geologists have to sample muck piles of broken ore are very common and includes sampling of the ore stock piles, conveyor belts, tram cars and draw points of the underground stopes (Fig. 5.5).Sampling approach is known as grab sampling and involves collecting of the rock chips of 3–5 cm in size.

Sampling for Assaying

Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting.

Ore Sampling

If the sample is perfectly dried before rolling and the rolling is done in such a manner as not to allow the ore to merely slide, it is much more quickly and thoroughly mixed by this method than by scooping it up and pouring it into a cone-shaped pile ; moreover, the fines tend to stick to the sample rather than to the glazed surface of the cloth.
