    The soft black mineral molybdenite (molybdenum sulfide, MoS2), looks very like graphite and was assumed to be a lead ore until 1778 when Carl Scheele analysed it and showed it was neither lead nor graphite, although he didn’t identify it. Others speculated that it contained a new element but it proved difficult to reduce it to a metal. It could be converted to an oxide which, when added to ...
