Luster: A mineral's luster is the overall sheen of its surface – it may have the sheen of polished metal, or that of an unpolished metal that is pitted by weathering – or it may have the sheen of glass, or look dull or earthy, etc. Luster should not be confused with color: A brassyellow pyrite crystal has a metallic .
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.
