Silica Sand Mining Process

Application:

For all glasses, silica sand is the most common ingredient, no matter the glass us window glass, boro-silicate glass, water glass, container glass or fiberglass. Silica sand makes up about 60~70 percent of glass batch and therefore it has a significant effect on the glass quality.

Mining process:

The whole silica sand mining process generally includes the following steps: crushing, grinding and separation. In the crushing process, the raw materials firstly sent into the jaw crusher for the primary crushing, if necessary, the crushed materials will enter in the impact crusher or cone crusher for further crushing. Then the minerals enter into the ball mill or grinding mill to be grinded. Next is the separation process. The separation process can be divided into flotation separation, gravity separation and magnetic separation.

Gravity separation:

According to the different minerals density in the silica sand, gravity separation is used to remove the heavy minerals to lower the iron content.

Flotation:

The flotation process is primarily used to remove the iron bearing heavy minerals in silica sand. The minerals are generally the same as the iron bearing minerals described in the gravity section. At times, flotation can also be used to remove mica.

Magnetic separation:

In silica sand mining process, various magnetic minerals are involved in it. We can use the magnetic separator to eliminate the undesired materials.
