Process Routes for High Purity Manganese Production. Most of the world's commercial production of high purity manganese is based in China and this summary contains information from operating Chinese production …
Manganese ore processing plays a vital role in producing various industrial materials. The process involves crushing, washing and separating the ore to produce manganese concentrate used in steel and battery production.
The manganese concentrate may expediently be used to produce metallic manganese and steel with low phosphorus content. That reduces Russia's dependence on imported manganese ore.
In 2023, after two years of growth, there was significant decline in the global manganese ore and concentrate market, when its value decreased by -18.5% to $10.7B. Overall, consumption, however, saw a relatively flat trend pattern. Global consumption peaked at $13.5B in 2019; however, from 2020 to 2023, consumption failed to regain momentum.
The raw ore was roasted in a reducing atmosphere, making the high valence iron manganese oxide reduce to a low valence state. 22 Subsequently, the iron and manganese components were separated through magnetic separation to recover a valuable iron bearing byproduct (magnetite concentrate) and manganese ore concentrate for ferroalloy production ...
Since its first ore shipment in 2006 25, the project has progressively mined these deposits for manganese ore to feed its 1 Mt-per-annum plant for the production of manganese concentrate. The company anticipates that mining activity for 2019–2020 will continue at mines planned in selected areas of the Chugga Far North, Tourag and Yaka ...

A surplus of pyrite is required for high extraction of manganese from its concentrate. At FeS 2:MnO 2 <1 the manganese recovery was less than 90%. Only at FeS 2:MnO 2 =1 did it reach 94.1–94.3% during 4 h (Fig. 2, curve 1). However, 5–6% of manganese was not recovered even at double surplus of pyrite.
Manganese (II) sulfate is produced by two major routes; directly by reaction of manganese (II) oxide (or manganese carbonate) with sulfuric acid or as a byproduct from organic oxidations with manganese dioxide. This dataset represents the production of manganese sulfate from manganese concentrate.
The concentrate scoping study followed an 80% uplift in the Oakover indicated mineral resource estimate, which now stands at 105.8-million tonnes at 10.1% manganese and combined with an inferred ...

China consumes 65% of the global output of Manganese ore (including 16% produced domestically), so around half of global Manganese ore production is imported by China from other countries, almost entirely by ship in bulk. Manganese alloy: Manganese alloy is mostly transported in bags of 1,000kg, by trucks and ships (sometimes in containers).
