2014-4-17 By: Juno Kim and Nicole. Introduction The goal of this experiment was to determine the mass percent of manganese in an unknown steel sample using methods of visible spectroscopy and volumetric analysis.The two methods were then analyzed and compared to decide the better method for determining the composition of Mn in the unknown steel.

2018-6-7 The manganese deposits of Fiji are becoming increasingly important but before many of them can be exploited a cheap beneficiation process will be required. Test work on a sample of ore from a low-grade deposit in S.W. Viti Levu showed that a marketable manganese concentrate could not
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. This would ensure much more consistent manganese content in the hot metal.
