The Preparation of High-Purity Iron (99.987%) Employing a

In this study, high-purity iron with purity of 99.987 wt.% was prepared employing a process of direct reduction–melting separation–slag refining. The iron ore after pelletizing and roasting was reduced by hydrogen to obtain direct reduced iron (DRI). Carbon and sulfur were removed in this step and other impurities such as silicon, manganese, titanium and aluminum were excluded from

Iron ore pricing explained Metal Bulletin

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke

Chemistry question!!!!!!!!!!? Yahoo Answers

Oct 26, 2008· The iron content of iron ore can be determined by titration with standard KMnO4 solution. The iron ore is dissolved in HCl, and all the iron is reduced to Fe2+ ions. This solution is then titrated with KMnO4 solution, producing Fe3+ and Mn2+ ions in acidic solution. If it requires 38.23 mL of 0.0221 M KMnO4 to titrate a solution made from 0.5995 g of iron ore, what is the mass of percent of
