Sphalerite is the primary carrier of In in various types of ore deposits. Despite its widespread occurrence, the content of In in sphalerite can vary significantly, from below detection to thousands of ppm, depending on the mineralisation style (Table 5) and the
What is Sphalerite? Sphalerite is a zinc sulfide mineral with a chemical composition of (Zn,Fe)S. It is found in metamorphic, igneous, and sedimentary rocks in many parts of the world. Sphalerite is the most commonly encountered zinc mineral and the world's most important ore of zinc.. Dozens of countries have mines that produce sphalerite.
In working to engage other scientists in research on deep-sea mining effects, Gartman is following in the footsteps of a pioneer deep-sea scientist at Duke University.

Global mining generates a large amount of mine tailings, which can produce negative effects on the environment. To counteract this, government guidelines and scientific interest have emerged to ...
Introduction. Trace element pollution in mining areas is always a huge environmental challenge for the global mining industry (Bhuiyan et al. 2010).With the weathering of pyrite waste, a large amount of harmful trace elements enter the soil, water, and surrounding environment (Chopin and Alloway 2007; Obiora et al. 2016).Pollution …
Added impetus to understanding these processes exists due to the potential for mining of seafloor massive sulfide deposits and potential environmental impacts of that activity. Here, we present a laboratory-based experimental study on the galvanic oxidation of sphalerite and synthesized zinc sulfide and coupled to covellite.
