Iron Removal Process for High-Purity Silica Sands

1999-9-28 · In this article, a leaching study, carried out on a quartz sample to obtain high-purity silica sands, has been presented. A leaching process by using oxalic acid to remove low iron content from the ore under study and to obtain a material suitable for fiber optic production has been evaluated. A characterization study has been carried out to establish the location of the iron impurities on the

A New Experimental Approach to Improve the Quality

When the objective of enrichment is to produce high purity silica from relatively low grade feed (generally 94% < SiO 2 < 98%), the use of reverse flotation in the processing circuit is unavoidable [12,13,14,15,16]. Some silica deposits contain impurities such as pyrite, iron oxides, and feldspar.
