Siliceous sand laboratories in Segovia

Our siliceous sand labs

The extraction of siliceous sands in Segovia has its history through the family business Arenas Silíceas Gómez Vallejo. Our laboratories are the place where we perform the tasks of washing, inspection and control of siliceous sands.

We have a team of professionals guided by a head of laboratory that is responsible for the verification of the processes and the identification of the minerals in terms of their nature or reference classification.

Depending on the studies carried out, the inspection and control of siliceous sands with granulometric tests, humidity or clays, among others, is considered. This is the simplest and least expensive method to be able to correctly separate the different raw materials by the difference of their specific weights during the process stages.
