Silica Sand Processing For Low Iron Contents

A process for leaching silica sand to reduce the iron content thereof comprises the steps of drying- preheating the sand vigorously mixing the preheated sand in a suitable intensive mixer e.g. a rotating pan mixer with sufficient sulphuric acid e.g. 7.5 kg 100 H2SO4tonne sand to keep the surface of each grain of sand coated with a thin film of sulphuric acid during mixing and retaining .

If the finished sand has a high iron content it will enter the pickling process. First it will be washed to remove powder and impurities and then pickled soaked and washed dried or cooled. Magnetic separation is mainly used to remove magnetic minerals in silica sand. For example weak magnetic minerals such as hematite limonite and .

Silica. Also called silica sand or quartz sand silica is silicon dioxide SiO 2. Silicon compounds are the most significant component of the Earths crust. Since sand is plentiful easy to mine and relatively easy to process it is the primary ore source of silicon. The metamorphic rock quartzite is another source.

Silica deposits are not a problem in most turbines where the silica content in the steam is below 0.02 ppm. Therefore it has become customary to limit silica to less than 0.02 ppm in the steam. Sometimes because of the more stringent operating conditions of certain turbines vendors specify that steam silica be maintained at less than 0.01 ppm.

The word sand denotes a material whose grain size distribution falls within the range 0.06-2.00 millimetres. The silica in the sand will normally be in the crystalline form of quartz. For industrial use pure deposits of silica capable of yielding products of at least 95 SiO2 are required. Often much higher purity values are needed.
