The coal sample, as received from the field, consists of 3 to 15 kg of material that first is reduced to a particle size of 2 to 4 mm (5 to 10 mesh) in a jaw crusher. This crushed material is then divided into three splits. The first split is forwarded to a laboratory for standard ultimate and proximate analyses.

It is desirable to use material which has as nearly the same metallurgical characteristics as the samples with which the standards will be included. This is usually a difficult chore. For many reasons, including the particle size at which a significant amount of the gold mineral is liberated, the sampling characteristics of even -150 mesh material may preclude the use of geologically and ...
