Silica Sand Washing System

SBM silica sand washing systems have been employed throughout the world to replace traditional, inefficient sand washing systems such as bucket wheels and sand screws / screw classifiers. These washing systems are employed in the production of specialist sands such as silica sand, golf sand and filter sand for use in municipal waste water treatment.

Silica Sand Processing

Silica sand is an industrial term used for sand or easily disaggregated sandstone with a very high percentage of quartz grains. Quartz is the most common silica crystal and the second most common mineral on the earth’s surface. It is found in almost every type of rock; igneous, metamorphic and sedimentary. Silica sand deposits are most commonly surfacemined in open pit operations, but dredging and underground mining are also employed.

Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.

Silica Sand Washing Operation

Silica sand may be produced from both unconsolidated sands and crushed sandstones. The sand is a product of mechanical and chemical weathering of quartz-bearing igneous
and metamorphic rocks such as granites and some gneiss. Erosion and chemical weathering break down the less stable minerals such as feldspars and release the more stable ones such as quartz and zircon. The stable mineral fragments are transported and redeposited in water. Wave and stream action may further modify the deposits by sorting and washing until a relatively pure deposit of silica sand remains.
