The Huanggangliang deposit is a super large Sn Fe deposit in the Huanggangliang Ganzhuermiao metallogenic belt in the southern section of the Great Hinggan Range The Sn Fe deposits mainly occur in the skarn contact zone and were formed via the interaction of biotite bearing alkali feldspar granite with limestone strata of the Permian
Magnetite is a mineral having the formula Fe3O4 or FeOFe2O3 A g sample of a magnetite ore was dissolved in concentrated HCl to give a solution that contained a mixture of Fe{eq}^{2 } {/eq} and Fe{eq}^{3 } {/eq} Nitric acid was added and the solution was boiled for a few minutes which converted all of the iron to Fe{eq}^{3 } {/eq}
