What Is Sand Mining Process
For new mining operators, they want to know detailed sand mining process line and this will be very helpful for the next production. Here will introduce the detailed silica sand mining process and the machine in India Karnataka.
Silica Sand 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.
According to the different minerals density in the silica sand, gravity separation is used to remove the heavy minerals to lower the iron content.
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.
In silica sand mining process, various magnetic minerals are involved in it. We can use the magnetic separator to eliminate the undesired materials.
