environmental implications of sphalerite

Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).

Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes.

Chalcopyrite

1. Introduction. Minerals are naturally occurring chemical compounds. They are an integral part of the natural environment, alongside microorganisms; thus, there are inevitable physicochemical interactions between minerals and microorganisms (Lu et al., 2012).For example, microbes can trap K + from the environment and supply K + for illitisation through metabolic activity (Aubineau et al., 2019).
