Arenas Silíceas Gómez Vallejo - Silica


Technical description

Silica sand is a compound formed when silica combines with oxygen. In other words, one silicon atom bonds to two oxygen atoms to make a very stable molecule, Si 02.

It is water-soluble and naturally found in the form of quartz: if it is crystallized it is called rock crystal.

Risks of silica: non-toxic and safe product

Currently at Arenas Silíceas Gómez Vallejo we have a processing plant where the raw sands received from quarries undergo different processes so that, in each case, the different granulometric curves respond with an optimal yield of the treated mineral, and the highest quality of the finished product, which allows us to meet the needs of the end user of both normal sands and those with special qualities which are often requested.

For these purposes, our operating facilities essentially have equipment that:

  • Washes raw sands.
  • Classifies (via wet method) raw sands.
  • Dries raw sands.
  • Classifies (via dry method) raw sands.
  • Packages raw sands.
  • Palletises raw sands.
  • Etc.

Industrial uses

These derive from their important physical and chemical properties, particularly their toughness, chemical resistance, high point of fusion, piezoelectricity, pyroelectricity and transparency.

Silica sand is the raw material which is fundamental for the manufacturing of glass (70 % of its composition) and of porcelain. In particular, our sands are used as filter beds for water treatment and purification (for the retention of very small floccules that are not separated through the decanting process); their toughness enables them to be used for the manufacturing of bleaches, industrial abrasives and sandblasting.

Additionally, they are a very important raw material in the formula composition of detergents, paints, special cements and mortars, and serve as the basic raw material to obtain silica. They are also the basis for the manufacturing of silica refractories and model sands due to their high point of fusion.

By following the process that we previously outlined, specific granulometric fractions can be produced in silica sands which are intended for such diverse industrial markets such as:
    • Silica sands for water filtration.
    • Silica sands for mining.
    • Silica sands for foundry.
    • Silica sands for glass.
    • Silica sands for mortars.
    • Silica sands for purification plants, sandblasting.
    • Silica sands for flooring.
    • Silica sands for paints.
    • Silica sands for resins.
    • Silica sands for crockery.
    • Silica sands for epoxy and sports fields.
    • Silica sands for golf clubs.
    • Silica sands for tennis.
    • Silica sands for riding arenas.
    • Silica sands for swimming pools.
    • Etc.
