    2. Mineral Processing Wastes Since cadmium is toxic to humans and certain other living organisms, care must be taken during the production, use, and disposal of cadmium and its compounds to avoid the dispersal of cadmium fumes and dusts or the release of cadmium-bearing effluents into the environment so that exposure is minimized.13 Listed below are

  • Cadmium: processing-Metalpedia

    Some plants produce cadmium oxide and/or metallic cadmium powder. Cadmium oxide is produced by melting the ingots and keeping a controlled oxidizing atmosphere in the retort. To produce metal powder, the melted ingots in the retort are kept under an inert atmosphere while cadmium is distilled into a condenser as metallic powder.

    DescriptionRelation to MiningUsesCadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process. Cadmium is therefore produced in countries where zinc is refined, not necessarily in the countries where zinc ore is mined. China, Japan, and Korea are the world’s largest producers, followed by Mexico, the United States, the Netherlands, India, the United Kingdom, Peru and Germany. Fifteen other countries produce smaller amounts.
