Whenever, it ispracticable to stop the conveyer belt periodically, alarge quantity of ore known as unit sample may bedrawn by stopping the belt. However, it should benoted that if possible, the samples should be drawnfrom the conveyor depending upon the category ornature of the ore and that lots shall be constituted ofthe same category or source of the ore. The mass ofdifferent unit samples shall not be less than thatgiven below and shall be collected from the full widthand thickness of the ores stream over a suitablelength of the conveyor.
