May 12, 2008#0183;#32;Commercial production of cadmium ore depends on the mining of zinc (ATSDR 1999). Cadmium is commercially available as an oxide, chloride, or sulfide. Cadmium metal (Cd 2+ ) refined from the ore is a silverwhite, bluetinged lustrous heavy metal solid at room temperature (National Toxicology Program [NTP] 2004).
Cadmium GreenFacts. 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 price
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 nickelcadmium (NiCad) batteries. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.
Lead and Mercury Emissions from Mining. Global releases of lead from smelting and refining nonferrous metals ( gold, lead, zinc, copper) total over 28,000 metric tons/year. 1 Global releases of mercury from smelting and refining nonferrous metals total 710 metric tons/year

Cadmium. Cadmium is an extremely toxic metal commonly found in industrial workplaces, particularly where any ore is being processed or smelted. Several deaths from acute exposure have occurred among welders who have unsuspectingly welded on cadmiumcontaining alloys or with silver solders.
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.
Cadmium: processing; Mining and beneficiation; Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock.
