2012-1-1 · Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 5.3.7 Manganese Ore. 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.

Manganese leaching in high concentration flue gas

Manganese leaching during high concentration flue gas desulfurization process with semi-oxidized manganese ore was studied in this paper. It was found that there were different reaction pathways among which MnO 2, Mn 2 O 3 and MnCO 3 in semi-oxidized manganese ore during flue gas desulphurization and manganese leaching. High SO 2 concentration facilitated redox reaction between MnO 2 and SO

Effect of Manganese on Silver Leaching

2020-6-11 · In Mexico and elsewhere there are large bodies of valuable silver ore containing manganese which present great, and hitherto insuperable, obstacles to a satisfactory extraction by cyanide. The proportion of the silver that is soluble in cyanide varies greatly and may be as low as 5% only. The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver
