Zimbabwe has rich deposits of minerals including diamonds, platinum, coal, uranium, lithium, gold, antimony, iron, and chrome. Bioleaching is defined as the use of microor-ganisms to facilitate the extraction of metals from sulphide or iron-containing ores or concentrates (Rawlings, 2022, 1997). Bioleaching has been shown to be an efficient (Blowes, Ptacek, and Jurjovec, …

Dunite is mostly composed of olivine which is a bright green mineral. Fresh rock is green as well. However, olivine readily alters and loses its bright green color pretty quickly. Chances are very high that on the way up in the crust olivine grains lost some of its brightness. Hence, many samples look dull yellow, not green anymore. This rock usually contains chromite (Mg-bearing …
