It is a cardinal principle of wet-ore dressing that the ore shall not be broken finer than is absolutely necessary to separate the rich mineral from the lean rock. This lessens the production of dust, which in treatment with water is always liable to float off. It is now not uncommon to find water jigs that treat ore of ¾ and 1 inch diameter.
