1. Introduction. Sphalerite (ZnS) is the principal ore mineral for zinc (Zn) and accounts for approximately 95% of the world's zinc mine production (International Lead and Zinc Study Group, 2021).The crystal structure of sphalerite allows it to incorporate a broad range of elements, occurring from trace (e.g., gallium (Ga), germanium (Ge), indium (In), …

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, …

Abstract. Trace element compositions of sphalerite and chalcopyrite have been investigated for four arc-hosted Cretaceous VMS deposits (María Teresa, Perubar, and Palma in Peru, and Cerro de Maimón in the Dominican Republic) using laser ablation inductively-coupled plasma mass spectrometry.

The sphalerite chemical formula is ZnS (zinc sulfide.) This chemical formula represents sphalerite in its pure form, but it is much more commonly found with significant amount of other elements substituting zinc. Up to 26 % Fe, 17 % Cd, 15 % Hg, 21 % Mn and small amounts of Cu, In, Ga, Ge and As may replace the zinc.
