  • List Metals used in Making Steel Alloys

    The principal ore of molybdenum is the sulphide, molybdenite, (MoS2). This may be changed by weathering into the yellow oxide, molybdite (MoO3) or to molybdic ocher, a yellow molybdate of iron. Where galena and molybdenite occur together, wulfenite PbMoO4, of a bright orange color, may be a product of weathering; and it is sometimes plentiful
