MANGANESE INDUSTRY ANALYSIS IMPLICATIONS FOR PROJECT

It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining. Besides their ores being regularly obtained from the same mines, manganese and iron are further linked due to their complementarity in steel production.

Manganese - Glocomda

A grey-white metal that resembles iron, manganese is hard and brittle, fusible with difficulty, but easily oxidised. Manganese is the twelfth most abundant element in the earth’s crust. Nevertheless it is rarely found in concentrations high enough to form a manganese ore deposit. It is designated by the symbol Mn and has an atomic number of 25.

RESEARCH: All change in global stainless markets?

Asia, despite being by far the biggest market for stainless steel these days, remains stuck dealing with the consequences both of trade measures elsewhere and rapid expansions in capacity at home. Margins and prices remain lowest in this region and, as we discuss in our Asia analysis this month, this will only be rectified by adjustments to local supply – a task that has often proved to be beyond producers there.
