Manganese (Mn) is not only one of the important elements in the earth's crust, which is essential to iron and steel production, aluminum alloys, an additive in unleaded gasoline, the reagent in organic chemistry etc, but also an essential element for human health, metabolism, and antioxidant system. The Mn deposits are of interest because they contain greater amounts of other metals that are found in today's known economically minable deposits. High quantity of Co, Ni, Cu, and Zn containing in the Mn deposits makes it a significant potential economic resource for these elements. The most identified deposits of manganese are in South Africa,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
