摘要：
Copper and nickel tenors in sulfide ores can be successfully measured in altered and unaltered rocks using automated mineralogy (by QEMSCAN). However, platinum-group element and cobalt tenors require separate geochemical analysis. The method provides additional mineralogical detail than the traditional geochemical method, and avoids mineralogical restrictions to the original sulfide assemblage. It furthermore allows for the determination of metal tenors in rocks with minor or trace sulfide; and provided the alteration regime is known, the method can also be used to back-calculate the original sulfide composition and metal tenors in altered ores.
