Aluminium ores -- Sampling procedures
This standard was last reviewed and confirmed* in 2008.
*Therefore this version remains current
Sets out requirements for the sampling from moving streams and stationary situations, including stopped-belt sampling, to provide gross samples for sample preparation. The procedures recommended may not be applicable in cases of extreme segregation, e.g. very wet ore due to its sticky nature, or very dry ore due to generation of dust.
