While the tiny particles travel through a spiral gravity separation process, the big particles are sent back into the crusher. This is how grinding is done in iron ore processing. Spiral Gravity Separation. The solid concentration range for gravity separation feed is around 30%. To help with the separation process, process water is employed.

As a result, a commercial process of manufacturing pure, flawless, electronics-grade quartz was developed. "Cultured quartz," that is, quartz crystals grown very carefully in highly controlled laboratory conditions, is the quartz that is used in industry. About 200 metric tons of cultured quartz is produced each year.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.
