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 zincsmelting countries of the world.
Cadmium is produced mainly as a byproduct of mining, smelting and refining of zinc and, to a lesser degree, as a byproduct of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickelcadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.
Mining stability monitoring provides persistent geotechnical risk surveillance to identify areas of abnormal surface movement over time. By assessing timedependent shape changes in Antares, geotechnical domain experts can identify patterns of instabilities. This is a direct pathway to improving asset management in mining operations.
