  • Cadmium: processing-Metalpedia

    The cadmium content of the zinc concentrate is usually around 0.3% to 0.5%. An estimated 90% to 98% of the cadmium present in zinc ores is recovered in the mining and beneficiating stages of the extraction process. Figure 1 shows a schematic flow of mining and beneficiating a typical lead-zinc ore. Figure 1.

  • Cadmium GreenFacts

    Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickel-cadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.Онлайн-запрос

  • Cadmium | Minerals Education Coalition

    Cadmium minerals are very rare and include cadmoselite (cadmium selenide), greenockite (cadmium sulfide) and otavite (cadmium carbonate). Cadmium substitutes for zinc in sphalerite, so most is recovered during the processing of zinc ores. It is produced in most zinc-smelting countries of the world.Онлайн-запрос

  • Cadmium poisoning Wikipedia

    Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure.Онлайн-запрос
