Responsible Mining Nimba Iron Ore Project Smfg

we, the soci des mines de fer de guin have been entrusted by the people of guinea to responsibly develop the nimba iron ore project and create a positive contribution for future generations. the project represents more than fifteen years of research, ores. niobium occurs mostly as an oxide and has a strong geochemical coherence with tantalum. major minerals of niobium are pyrochlore Nb and columbite consisting of niobate, tantalate, iron, and manganese.pyrochlore occurs usually in carbonatites and in pegmatite derived from alkalic rocks, commonly in association with zirconium, titanium waste called tailings, the residue of an ore that remains after it has been milled and the desired metals have been extracted or sulfuric acid If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then the mine project will generate a similar quantity of
