Gravity concentration tends to recover the pyrite with the gold, and only removes the lighter minerals, such as quartz, from the ore. The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine.
Parting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary.
