 · Bulk density is a measure of mass per unit volume of rock and in South Africa it is generally expressed as metric tonnes per cubic metre. Density is determined by measuring the mass of a sample and dividing this by its volume. Generally the dry mass is obtained by drying the sample and then weighing it, which is the easy part.
