  • Genetic Model of Ore Deposits ~ Mining Geology

    May 18, 2015· Most molybdenum skarns contain a variety of metals including W, Cu, Zn, Pb, Bi, Sn, and U and some are truly polymetallic in that several metals need to be recovered together in order for the deposits to be mined economically. Mo W Cu is the most common association and some tungsten skarns and copper skarns contain zones of recoverable molybdenum.
