how to remove silica from iron ore

Silica – Eco

A Silica deposit with material of more than a 7 on the Mohs scale is an exceptionally rare and valuable material. Purity of the deposit is also extremely important. A common impurity found in Silica which can make it economically difficult to process is Iron. Too much Iron and the Silica is not viable. Another common element is Gold.

Aluminium

Bauxite ore contains sufficiently high levels of aluminium oxides and suitably low levels of iron oxide (Fe 2 O 3) and silica (SiO 2) to be economically mineable. The amount of reactive silica is particularly important as this form of silica consumes the caustic soda needed to make alumina, thus low reactive silica is desirable.
