Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills. Concentration is effected by washing, and the " concentrates " are chlorinated by the Plattner process. A further operation divides the waste products into 60 per cent, of " tailings " and 40 per cent, of "slimes," and these materials ...
