Ferruginous Manganese Ore—A Comparative Study

2021-2-2 · the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of mineralogy on their magnetic separation performance.

Ore petrography of low-grade siliceous manganese

2011-11-1 · Massive-mosaic type ore. The siliceous manganese ore of Sone-Patuli near Patmunda (the OMM lease hold) is of the massive-mosaic type (see Fig. 2d). The samples are dominated by crystalline quartz with cryptomelane being the major manganese mineral (see Figs. 3c and d). Quartz grains show a disconnected linear pattern (see Fig. 2d). The ore is massive, hard, and compact in nature.

Further, the two-stage separation was adopted to discard hematite and goethite at a lower magnetic field intensity of 0.4 T and iron-bearing silicates at 1.2 T. The two-stage separation for such low-grade ferruginous chromite ore is well reported in the literature . The results of the two-stage separation are found to be insignificant as there is an incremental change in the grade, but the recovery decreases

depends largely upon the nature of the impurities present in the ore under investigation. Previous work in this laboratory involved highly siliceous ores2 which were amenable to froth flotation and highly ferruginous ores' which required leaching with dilute acids. The ore employed for this work was from Keshapur Mines, Shimoga, Mysore State.
