how to reduce silicon dioxide from washing in iron ore

Iron ore often has silicon dioxide (sand) impurity which must be removed during the process. To do this limestone is added to the charge. The limestone (chemically, calcium carbonate) decomposes in the heat of the furnace to calcium oxide. This calcium oxide can then react with the hot sand (silicon dioxide) making a chemical called calcium ...
