Jun 10, 2019· Manganese Ore . Ukraine is in the top ten producers of manganese ore in the world and has the largest manganese ore reserve in Europe. In 2010, the country produced over 736,000 metric tons of marketable manganese ores and concentrates, of which some 121,000 metric tons were exported and the rest used domestically to produce ferroalloys.
Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.

they are rich enough in manganese to be of ore grade. Others are "secondary ore"—zones where the original manganese content of the sediments has been naturally enriched by younger geologic processes. Nearly all manganese ores are beneficiated near the mine sites to improve the manganese grade before further processing.
The ore body varies in c omposition from pure manganese ore to pure ir on ore but it generally represents a mixtur e of the two ore in v ariable concentra tions. Small lenses are richer in Mn than the
