Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Aug 14, 2019· Iron ore (coarse grade) Manufacture Current magnetite production is a byproduct of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by ''cleaning'' and ''recleaning'' of the magnetic concentrate from the first stage.
A new pigiron making process using magnetite ore pellets containing coal as reducing agent has been investigated. The pellets were heated rapidly in argon at furnace temperatures between 1573 and 1723K and the temperature and partial pressure of oxygen in the pellets were recorded in situ. Molten iron .
