6 Methods for Removing Iron From Silica Sand Mining Pedia
网页2021年11月30日01 Iron Removal by Mechanical Scrubbing. Mechanical scrubbing is to remove the thin film iron on the surface of the silica sand and the iron-containing minerals adhering to the surface of the silica sand by means of mechanical external force and the collision and friction between the sand particles. At present, scrubbing techniques are

Acid leaching of silica sand Laboratory TestingGeneral
网页If you have mainly iron and at low concentration (max. about 100 ppm), you may get away with an oxalic leaching as a first step test and see. If you have higher iron, not to mention other deleterious elements (Ba, Mg, Al, Ca, Ti, Zr, etc.) you may want to consider hydrochloric acid leaching. Sulfuric acid will not dissolve barium.

High efficiency iron removal from quartz sand using phosphoric acid
网页2012年11月21日4. Conclusions. Our experiments have verified that the phosphoric acid is one of the best leaching agents in the purification of iron impurities from the quartz sand because of the properties of H 3 PO 4 itself. H 3 PO 4 has advantages of a high leaching rate, low cost of production, simplified flow sheet, and of less harm to our target product.
