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.
Since the world is now confronting lower Mn ore grades due to the depletion of high-grade Mn ores [11][12][13], investigating the use of lowgrade ores in industrial processes is of high importance.
Fines of -1mm or -0.5mm in size can not be sintered. Fines (all -1mm with more than 50% -0.5 mm fraction) can also be sintered. Achievable through control of balling method, moisture …
Due to the randomness of all factors influencing the sintering operation, a two-stepped procedure is proposed to find the best way of using stocked fines at a plant producing Fe-Mn alloys for the steelmaking industry. The approach is based on the following: (1) predict the result of the sintering operation by establishing the best multilinear regression model using some of the …

Manganese ore sintering process relies on a number of complex process parameters. This paper seeks to describe some design considerations of sinter plants.
Ore fines are not readily treatable in SAFs and sintering of ore fines is applied as the main agglomeration technique. Primary manganese ferroalloys, namely HCFeMn and SiMn, are produced in SAFs. Although these are mature technologies, the processes are electrical energy intensive and produce significant amounts of CO 2 gas.
