Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral concentration processes.

Cadmium, a soft, malleable, ductile, bluish-white metal, was discovered in Germany in 1817, and Germany remained the only important producer for 100 years. Currently, a large percentage of global cadmium metal production takes place in Asia. Cadmium is generally recovered as a byproduct from zinc concentrates.

The original cadmium is a rare soft metal, similar to zinc but much harder to find naturally in the earth. It was only when it was discovered as a by-product of the zinc refining process that it became used a commercial pigment. This discovery took place in 1817, when the German chemist Friedrich Stromeyer was inspecting pharmacies.

Mar 5, 2021Specially, 0.5 g of each pyrite ore sample was used to extract four geochemical fractions of heavy metals (acid extractable, reducible, oxidizable, and residual fraction). The acid extractable fraction was obtained employing 20 mL CH 3 COOH (0.11 mol/L, pH = 2.8). The reducible fraction was obtained using 20 mL NH 2 OH·HCl (0.50 mol/L, pH = 1.5).

Cadmium does not occur uncombined in nature; greenockite, a cadmium sulfide mineral first found in Scotland, is the only commercial ore. Cadmium is obtained principally as a byproduct of the smelting and refining of ores of zinc, especially zinc sulfides, and of lead and copper. The element was discovered in 1817 by Friedrich Stromeyer.
