Unlike steel demand, which is typically steady, the supply of manganese is declining. The price of pure manganese has risen to roughly $2,800 a tonne (metric ton), nearly double what it was in 2015. The demand for electrolytic flake manganese - the kind used in batteries - is now outpacing supply by about 25,000 MT. There has rarely been more opportunity to enter the manganese supply chain than at this point.
