Potential mobilization of cadmium and zinc in soils spiked with

Particulate cadmium (Cd) and zinc (Zn) are ubiquitous in agricultural soils of Pb–Zn mining regions. Water management serves as an important agronomic measure altering the bioavailability of Zn and Cd in soils, but how this affects particulate Cd and Zn and the underlying mechanisms remain largely unknown. Microcosm soil incubation …

THE INCORPORATION OF CADMIUM, MANGANESE AND FERROUS IRON IN SPHALERITE

Techniques of atomistic simulation have been used to study the incorporation of the M 2+ impurities iron, manganese and cadmium into sphalerite. The calculations show that bulk impurity ions are most easily incorporated by direct substitution at the Zn site, and that the substitution energies exhibit a linear relationship with ionic radii.

Sphalerite Value, Price, and Jewelry Information

Consult our sphalerite buying guide for more information. Use protective settings for these gems, especially if worn as ring stones. This 18K gold cocktail ring setting allows light to enter the 35.7-ct sphalerite center stone but still protects it from scratches and blows. The ring also features pavé diamonds and tiny sphalerites.

Sphalerite | U.S. Geological Survey

Sphalerite 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 is primarily consumed for the production of rechargeable nickel cadmium batteries; other end uses include pigments, coatings and …

Trace and minor elements in sphalerite: A LA-ICPMS study

Sphalerite is an important host mineral for a wide range of minor and trace elements. We have used laser-ablation inductively coupled mass spectroscopy (LA-ICPMS) techniques to investigate the distribution of Ag, As, Bi, Cd, Co, Cu, Fe, Ga, Ge, In, Mn, Mo, Ni, Pb, Sb, Se, Sn and Tl in samples from 26 ore deposits, including specimens with …

Potential environmental risk of natural particulate cadmium

Cadmium (Cd)-bearing sphalerite and smithsonite ore particles are ubiquitous in soils near metal-mining areas. Previous studies indicate that smithsonite is more readily dissolved in acidic waters and soils than sphalerite but the mobility of Cd and zinc (Zn) derived from these ores in soils is unkn …

Sphalerite: The primary ore of zinc and a collector's gem.

The chemical formula of sphalerite is (Zn,Fe)S. It is a zinc sulfide containing variable amounts of iron that substitutes for zinc in the mineral lattice. The iron content is normally less than 25% by weight. The amount of iron substitution that occurs depends upon iron availability and temperature, with higher temperatures favoring higher iron ...
