The existence of iron impurities greatly reduces the use value of silica sand and affects the quality of products. For example, in glass production, iron impurities will do great harm to the production and quality of glass, especially to the thermodynamic properties of glass melting process and the transparency of glass products.
Industrial minerals, such as silica sand, kaolin and feldspars, are often contaminated with deleterious impurities of unwanted components, particularly in the form of iron, titanium and aluminum oxides. These impurities cause serious problems during

The present invention refers to a process of purifying silica sand and, more particularly, it is related to a process for removing, from silica sands which are to be used as a raw material for glass manufacture, ceramics and the like, practically all of the iron and aluminum impurities contained therein.
The upstream washing water can maintain sand particles in suspension to avoid the sand sinking to the tank bottom and maintain discharge of impurities through overflow in order to prevent from reattachment of the impurities to particle surfaces. Evaluation of effects to extract iron from silica sand
Aug 02, 1994· What is claimed is: 1. A process for purifying silica sand, consisting: a) abrasiveattritioning a sand particle mixture by subjecting the sand particles to centrifugal rotation under dry conditions, while simultaneously agitating the particles with translative eccentric, downstream, and upstream movements, wherein the surface impurities are removed from the sand particles, and
What is Industrial Sand (silica sand) Industrial sand is a term normally applied to high purity silica sand products with closely controlled sizing. It is a more precise product than common concrete and asphalt gravels. Silica is the name given to a group of minerals composed solely of silicon and oxygen, the
In this article, a leaching study, carried out on a quartz sample to obtain highpurity 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 ...
Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than % Fe2O3. ... Treatment is generally limited to production of highquality glasssand by removal of impurities. For ...
