The most effective separations of nonmetallic minerals are accomplished where a single basictype mineral is floated from one or more acidictype minerals, as for instance the flotation of crystalline fluorite from quartz. This separation depends upon the fact that the two minerals may be readily freed from each other by grinding to flotation particle size.
