• Bismuth resources, reserves and production-Metalpedia

    The world reserves of bismuth containing ore stands at 320,000 tonnes and the reserve base is estimated to be 680,000 tonnes. The mined bismuth content production in 2013 can be seen in the table below. In 2013, worldwide total bismuth mining production was 7,600 tonnes, falling 0.7% (600 tonnes) compared with last year’s figure of 8,200 tonnes.

  • Lead Production Statistics < Lead Facts ILA

    Lead ores are mined at a rate close to 5 million tonnes a year and the world market for refined lead stands at about US $15 billion. While it has a high economic value, lead is relatively economical to produce. As with all metals, there are two main production routes. Primary production from mined lead ore is of course the original source of
