    Cadmium is Obtained as a By-Product of the Smelting and Refining of Sulphide Ores The only cadmium mineral of any economic importance is that of Greenockite (CdS) that is mostly associated with sphalerite (ZnS). It is, in the main, obtained for commercial purposes as a by- product in the mining industry through the smelting and refining of sulphide ores of copper and lead, specifically zinc

  • 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. Other major uses of refined cadmium are: pigments for plastics, ceramics and

  • Cadmium: processing-Metalpedia

    Cadmium: processing; Mining and beneficiation; Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock. The ground ore is usually treated by a differential flotation process to separate the zinc-bearing particles from the waste rock

  • Cadmium Minerals Education Coalition

    Relation to Mining. Cadmium 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

    Workers can be exposed to cadmium in air from the smelting and refining of metals, or from the air in plants that make cadmium products such as batteries, coatings, or plastics. Workers can also be exposed when soldering or welding metal that contains cadmium. Approximately 512,000 workers in the United States are in environments each year where cadmium exposure may occur.

    Cadmium (Cd), a toxic heavy metal considered a hazardous substance, is a waste byproduct of mining, smelting and refining sulfidic ores of zinc during zinc refining, and therefore its production does not depend on PV market demand. CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future

  • Environmental Cost of Refineries

    The refining processes that are typically found paired with hardrock mining are just as harmful to the environment as the mining itself; perhaps even more so. Although mining exposes all of the contaminants, refining isolates and concentrates waste, in order to isolate and concentrate the desired final product. Refining processes also often use harsh acids and bases to separate the desired
