Cadmium: processing-Metalpedia

Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zinc-bearing secondary materials using either a hydrometallurgical or pyrometallurgical process.

Cadmium - GreenFacts

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.

Cadmium - Wikipedia

Cadmium makes up about 0.1 ppm of Earth's crust. It is much rarer than zinc, which makes up about 65 ppm. No significant deposits of cadmium-containing ores are known. The only cadmium mineral of importance, greenockite (CdS), is nearly always associated with sphalerite(ZnS). This association is caused by geochemical similarity between zinc and cadmium, with no geological process likely to separate them. Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfi

All the information on Cadmium - Introduction

Cadmium is Natural. Cadmium (elemental symbol Cd and CAS registry number 7440-43-9) is a member, along with zinc and mercury, of Group 12 (CAS IIB) of the Periodic Table of the Elements. It is generally characterized as a soft, ductile, silver-white or bluish-white metal, and is listed as 64 th in relative abundance amongst the naturally occurring elements.

Itai-itai disease - Wikipedia

Causes. Itai-itai disease was caused by cadmium poisoning due to mining in Toyama Prefecture. Regular mining for silver started in 1589, and soon thereafter, mining for lead, copper, and zinc began. The earliest records of mining for gold in the area date back to 1710. Cadmium is a metal byproduct of mining that is toxic to most organisms.
