Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.

Improvement in electrowinning manganese dioxide, or zinc in which the relative concentration of manganese or zinc ions to impurities is enhanced by selectively extracting manganese or zinc ions from a bleed taken from the electrowinning feed stream with an organic extractant, while rejecting impurities, stripping the loaded organics with spent electrolyte, and recycling loaded strip to the ...
