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.
Cadmium is not the principal recoverable constituent in any ore, but it does occur at a ratio of about 1:200 with zinc. If lead and zinc are considered major products, then the major metal byproduct of the zinc industry was the more than 3 million pounds of cadmium produced in the .

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.
The dumps of the past mining operations leach zinc and cadmium, and the sediments of the Geul River contain non-trivial amounts of metals. About two thousand years ago, emissions of zinc from mining and smelting totaled 10 thousand tonnes a year.

Cadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife. Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickel-cadmium (Ni-Cad) batteries. Relation to Mining
Zinc-to-cadmium ratios in typical zinc ores range from 200:1 to 400:1. Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, will often substitute for zinc .

Zinc, in commerce also spelter, is a metallic chemical element ; it has the symbol Zn and atomic number 30.
Cadmium is a common impurity in zinc ores, and it is most often isolated during the production of zinc. Some zinc ores concentrates from sulfidic zinc ores contain up to 1.4% of cadmium. In the 1970s, the output of cadmium was 6.5 pounds per ton of zinc.

Dec 10, 2013· Cadmium is also found in meat, especially sweetmeats such as liver and kidney. In certain areas, cadmium concentrations are elevated in shellfish and mushrooms (Jarup 2002). Cadmium can also enter the food chain from water. In Japan, zinc mining operations contaminated the local water supplies with cadmium.
Cadmium. Cadmium is a soft, bluish-white, ductile metallic element that occurs in association with zinc ores. Its main use is in the production of nickel cadmium batteries. Copper. Nyrstar produces copper in concentrate and copper cathode. Copper is a soft, but tough metal, and it is an excellent conductor of heat and electricity.
Cadmium and zinc concentrations in kidney and liver have been measured under different exposure situations in different species including man. The results show that zinc increases almost equimolarly with cadmium in kidney after long-term low-level exposure to cadmium.
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.
