The problem involved in Manganese Ore Processing deals with the production of acceptable specification grades of manganese concentrates at a maximum recovery of the total manganese from ores having variable characteristics.
Manganese Ores. Some manganese minerals and mineraloids are considered “primary ores,” because they are rich enough in manganese to be of ore grade. Others are “secondary ores.” These occur in zones where the original manganese content of the sediments has been naturally enriched by younger geologic processes.

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.
for the beneficiation of low grade manganese ore fines as well as sintering of the concentrate. Manganese Ore Deposits The manganese ore was first produced in Visakhapatnam district, Andhra Pradesh in 1892. India was the largest manganese ore producer in the world until 1912, when the USSR over-took her, followed by South Africa, Australia,

manganese was in the range of 100,000 to 200,000 metric tons. Annual ore consumption was about 100,000 tons, of which approximately 90% was derived from imported ore. World production of ore was in the range of 1 to 2 million metric tons. Domestic ore production, which virtually had ceased by 1970,

In manganese processing: Ores. The most important manganese ores are the oxides pyrolusite, romanechite, manganite, and hausmannite and the carbonate ore rhodochrosite. Rhodonite and braunite, both silicate ores, are frequently found with the oxides. Only ores containing greater than 35 percent manganese are considered commercially exploitable.

The same source goes on to say that iron mining at Ilfeld ended for good in the very early 19th century, when manganese mining took its place; Bruhns, however, wrote in 1906 that "red iron oxide ores are mined," together with manganese ores, on Monchenberg.
According to the metal content in typical ore concentrates (i.e. most common copper mineral is Chalcopyrite CuFeS 2; an average copper concentrate contains 26% of copper (European Copper Institute, 2014)) we estimated the total amount of shipped ores resp. concentrates .
The material subjected to analysis is a large flow of iron-ore concentrate mixed with water. It forms a liquid slurry that is composed, for 72±2% (per weight), of ground mineral (65% smaller than 50 μm with occasional particles >5 mm) and water.
Where the oxidized ore is a manganese oxide ore, it usually contains appreciable rhyolite which tends to float. Therefore, a gangue depressant such as triisooctyl phosphorothionate is added to suppress the flotation of ryholite in the manganese concentrate.
There still remain to be considered the penalties and premiums which respectively increase and decrease the treatment charge. One common provision is the graduated increase in the base charge according to value up to a maximum charge, but this is partially offset by increasing the gold payments within certain limits.
