Manganese is usually found as a casting; or wrought into shapes such as bar stock, plate, angles, etc. Manganese steel is expensive to machine, which is why most parts are cast to shape and finished by grinding. As cast, Manganese steel that has not been heat-treated is very brittle because of the Manganese carbides.

grinding-derived Cu–Mn mixed oxalate precursors (GO-AS) prepared by a short grinding time of 2 h. For comparison, the XRD results of the single copper oxalate and manganese oxalate prepared in the same way as well as the mixed oxalate precursors (CO-AS) obtained by con-ventional aqueous oxalate coprecipitation are also given in

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.

A minimum of -35 mesh BSS has been found necessary to give 95% recovery of the contained manganese. Grinding of reduced ore is easier, since the reduced ore is much softer, but grinding also reoxidizes some of the manganese, which affects the leach recovery to some extent. Therefore, grinding to -35 mesh preceeds reduction.
