9.4 Silica. Silica is called silicone dioxide based on its chemical compound. Silica is made from the richest elements in earth's crust, which are oxygen and silicon. 56% of the covered earth contains silica, and 95% of it is rocks. Main crystalline silica are divided into three; cristobalite, tridymite, and quartz.
Also known as white sand, quartz sand or industrial sand, silica sand is a combination of two elements – silica and oxygen. It comes in a wide range of shades, mostly white or colourless. The colour of the sand depends on the rock detritus and the minerals that make up the resource. The quartz material in the sand, in particular, is obtained from sources …
The silica sand will be slurried and pumped to an off-site processing plant located near the railway line connecting the Kwinana Terminal, for beneficiation and production of saleable silica sand products. The silica sand products will be exported in bulks from the Kwinawa Terminal.
