cadmium separation from zinc sulphide

Zinc cadmium sulfide Wikipedia

Zinc cadmium sulfide is a mixture of zinc sulfide (ZnS) and cadmium sulfide (CdS). It is used for its fluorescent properties. Bioaccumulation of this chemical may occur along the food chain, for example in plants and in seafood. Long-term or repeated exposures are expected to have harmful effects on the kidneys, bones, and respiratory tract, resulting in kidney impairment, osteoporosis (bone weakness), and chronic inflammation of the respiratory tract.

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.

Toxicity and Related Data on Zinc Cadmium Sulfide

Zinc cadmium sulfide (ZnCdS) (CAS NO. 68583-45-9) was manufactured originally by the New Jersey Zinc Company and later by the U.S. Radium Corporation in New Jersey. The ZnCdS used in the Army studies appeared as a yellow or green (depending on whether copper or silver was used as an activator), somewhat fluffy powder under visible light. It was composed of about 80% zinc sulfide, ZnS, and 20%

Preparation and characterization of urchine-like cadmium

The wurtzite cadmium zinc sulfide can be described as a number of alternating planes composed of tetrahedral-coordinated S 2-and Cd 2+ or Zn 2+ ions stacked along the c-axis. The most common polar surface of cadmium zinc sulfide is the basal plane.
