In June 1976 a 600tonne/day manganese ore sinter machine, with on-strand cooling, was commissioned at the plant of Tasmanian Electro Metallurgical Company Pty. Ltd. at Bell Bay, Tasmania. This machine was installed in order to utilize manganese lump ore screenings generated in the preparation of raw materials prior to charging to the electric smelting furnaces at Bell Bay.
After beneficiation sintering / pelletization of iron ore, beneficiation and sintering of manganese ore fines attracted technology experts due to massive expansion in manganese based ferro-alloys. Fast depleting high grade lumpy manganese ore deposits made the beneficiation and sintering all the more wanted solution.

Sep 06, 2014 However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature elevation system were investigated to improve the strength of fired manganese ore pellets.
However, for the efficient manganese ores sintering process, the biofuel of high pyrolysis temperature of 1273 K is required. To achieve the specific capacity and the yield to be as high as those when coke breeze is only used, the amount of the biofuel for manganese ore sintering should be less than 25 wt.% of the solid fuel.
The sintering process employed for manganese ore and the siliceous ores used to produce silicomanganese results in partial reduction of MnO 2, Mn 2 O 3, and Mn 3 O 4 in the ore to MnO by reaction with carbon in addition to agglomerating the fine ore and coke. New technology also utilizes .

Kalagadi beneficiate the ore to produce 2.4 million tonnes of sintered manganese at a grade of 44-48% manganese. The difference between the sintered output tonnage and the 3 million tons of ROM ore is essentially the CO2 and moisture that is driven off from the Manganese Ore, which upgrades the Manganese content of the Ore.
