During washing of the silica sands, the fines < 40 µm are deslimed and dewatered on modern membrane filter presses to a residual moisture content of around 20 mass %. Here considerable quantities of kaolin filter cakes are produced as a recycled product with long-term assured supply.

Silica sand consists of fine pieces of quartz and other minerals such as salt, silt, clay, dust and various powders. Washed sand goes through a cleaning or “washing” process that removes these additional substances. MS Industries is a provider of naturally occurring smaller sized silica sand with microproppants and proppants.

Silica sand washing process. Washed and graded. The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is the opposite. This phenomenon is especially obvious in quartz sand containing a large number of clay minerals. Therefore, the quartz sand ore before the selection is carried out.

Washed Sand. ‘Washed’ refers to the process of removing clay, silt, dust and other unwanted particles from the sand. Once the excess materials have been removed, the sand is left to drain. Washed sand is ideal for rendering, mixing concrete and for making a less malleable mortar that is often used for and flagstones.

However, silica sand is currently being mined and’washed from the St. Peter only in LaSalle and Ogle Counties. In these areas, the formation varies from 140 to over 200 feet thick. It is mined only to a maximum depth of about 90 feet, due to water problems and increasing iron content at depth. All of the mining is done by open-pit methods.

The separated sand and clay gets dumped out in a pile in a back field or woods area somewhere, and goes back to nature. Once all the clay is removed (consisting of possibly 50% or more of the volume of gravel removed for cleaning), I''d apparently still need to bring dump trucks full of fresh washed gravel to replace the large volume of clay removed.
