cadmium mining ores

Cadmium: processing-Metalpedia

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.

Cadmium ore: Mineral information, data and localities.

An ore of cadmium. This is frequently a by-product of the production of other metals, in particular zinc, so cadmium ore may also be zinc ore.

Cadmium Statistics and Information - USGS

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 in the sphalerite crystal lattice.

Cadmium resources, reserves and production-Metalpedia

Cadmium is usually produced as a byproduct in the recovery of primary zinc from zinc ores, and also from some lead ores or complex copper-lead-zinc ores. However, it is generally agreed that the cadmium in lead and copper ores is associated with the zinc sulfide present rather than with the other minerals.

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 Minerals Education Coalition

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 - Overview Occupational Safety and Health ...

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817 ...

The sulfide ore of cadmium is termed as greenockite (CdS). Currently, cadmium is obtained from the mining, smelting and purification of ores of zinc sulfide, and copper sulfide. Elemental form of cadmium has been found in Siberia. The leading producers of cadmium in the world are Japan, China and South Korea and North America.

The mineralogy of Cadmium - Mindat.org

Most widespread minerals containing Cadmium; This list of minerals containing Cadmium is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Cadmium
