Dec 1, 2021 · 1. Introduction. Sphalerite is one of the most common sulfides and by far the most economically abundant source of zinc. Sphalerite often contains Fe, Mn, Cd, Ga, Ge, In, Se, Te and other trace elements, and these elements contain a lot of genetic information and also are important resources for critical metals (Huston et al., 1995, Tu et al., 2004, …

Oct 7, 2020 · Commodity Zinc is a brittle, whitish metal used in a wide range of industries, most familiarly as a galvanizing material for steel. Known and used for millennia, it was named “zinc” in the early 1500s by Paracelsus, a Swiss physician and philosopher. The name was derived from “zinke,” a German word for “fork tooth,” referring to the form zinc …

Aug 12, 2014 · Sphalerite is a common sulphide and is the dominant ore mineral in Zn-Pb sulphide deposits. Precise determination of minor and trace element concentrations in sulphides, including sphalerite, by Laser-Ablation Inductively-Coupled-Plasma Mass-Spectrometry (LA-ICP-MS) is a potentially valuable petrogenetic tool. In this study, LA …
