The use of the spirals in the processing of silica sand is a reversal of their original role. The quartz grains in the spiral water stream move to the outer edge as con-centrate and the heavy minerals move towards the inner edge as tailing[15] . The width of the product (silica sand) band and the tailing were controlled by ad-justable splitters.

silica, compound of the two most abundant elements in Earth's crust, silicon and oxygen, SiO 2. The mass of Earth's crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks. Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite.
