Sampling in Mineral Processing - Minerallurgy

Mineral processing sampling methods. Sampling can be done in a simple way, which is collecting some portions of materiel from different locations; or when the ore is transported in wagons or conveyor belts. After that we can mix all portions to form one large sample for measurement and test work. This called the grab sampling.

1.8 ADVANTAGES OF SAMPLING OVER CENSUS The advantages of sampling over complete census may be outlined as follows: 1. Sampling requires less time and labor than census because only a part of the population has to be examined. The sampling results also can be analysed much faster; 2. Sampling usually results in reduction in cost in terms of money and man powers.
