    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.

    Review on solvent extraction of cadmium from various ...

    Jan 01, 2012  A number of acidic extractants, namely D2EHPA, Ionquest 801, Cyanex 272, naphthenic acid and Versatic 10 acid were used for the extraction of cadmium(II) along with silver(I) and copper(II) . The order of extraction was found to be D2EHPA > Ionquest 801 > Cyanex 272 and naphthenic acid > Versatic l0 for cadmium(II).

    Cadmium - Wikipedia

    Cadmium is a component of some compound semiconductors, such as cadmium sulfide, cadmium selenide, and cadmium telluride, used for light detection and solar cells. HgCdTe is sensitive to infrared [38] light and can be used as an infrared detector, motion detector, or switch in remote control devices.

    Liquid–liquid extraction - Wikipedia

    Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to

    All the information on Cadmium - Introduction

    Cadmium is Useful. Most cadmium metal today is produced as a by-product of the extraction, smelting and refining of the nonferrous metals – zinc, lead and copper. Rather than disposing of it as waste into the environment, engineers have been able to utilize its unique properties for specific industrial applications.

    Cadmium Statistics and Information - USGS

    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.
