In other plants a ball mill or a tubemill will do all the grinding, but it must be fed with fine ore—say, 1/8 to ¼ inch—to do this properly. Grinding coarse ore in a ballmill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tubemill by 2 and 1½inch balls or by flint pebbles or by hard, rounded mine ...
