Chromium and its negative effects on the environment Case Studies
Chromium is mined in different countries around the world (such as South Africa, Zimbabwe, Finland, India, Kazakihstan and the Philippines) as the naturally occurring form, chromate ore (FeCr 2 O 4).Chromium is unstable in an oxygenated environment and, when exposed to air, immediately produces an oxide layer which is impermeable to further oxygen contamination.

Processing of Iridium and Iridium Alloys
Plasma melting of Ir is performed at a moderate pressure of about 50 Pa and provides for some purification by vaporisation of impurities, although to a lesser extent than with electron beam melting. In some cases, the final melting operation prior to deformation processing ( 12) is electron beam melting (discussed above under purification).
