Sampling for Assaying - Mineral Processing & Metallurgy

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. Having taken a large representative sample by chiseling 3″ to 6″ wide and 1 ...
