  • Cadmium - Wikipedia

    Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfidic ores of zinc, and, to a lesser degree, lead and copper. Small amounts of cadmium, about 10% of consumption, are produced from secondary sources, mainly from dust generated by recycling iron and steel scrap.

  • All the information on Cadmium - Alloys

    Copper-cadmium alloys which have almost double the mechanical strength and wear resistance of pure copper, yet still retain 90 per cent of its conductivity, contain between 0.8 to 1.2 per cent cadmium. In addition, copper-cadmium alloys can be severely cold rolled without making them susceptible to softening during soldering.

    Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacial coating," corroding before the substrate material. The 5-20 Mesh size offers increased surface area for plating. Cadmium Oxide is used in electronics as a transparent conductor.

    Abstract Quantitative estimates of cadmium (Cd), copper (Cu) and zinc (Zn) flows in percolating soil water and in surface run-off on arable land are rather scarce. Such information is essential for establishing reliable mass balances of trace metals, e.g. on field level, due to the fact that the trace metal outputs in water are quantitatively significant in field balance calculations.
