Silica is typically received in the form of metallurgical grade gravel. This gravel is 99.5% silica, and is 3 x 1 or 6 x 1 in (8 x 3 cm or 15 x 3 cm) in size. The coal is usually of low ash content (1-3% to minimize calcium, aluminum, and iron impurities), contains around 60% carbon, and is sized to match that of the gravel.

Where possible, its always a good idea to avoid using any method or machinery that produces a lot of silica dust. For example, Abrasive blasting is quite common in mining, but it produces an enormous amount of silica dust when sand is used. Using alternatives such as aluminum oxide would reduce the amount of silica dust that goes into the air.
About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia and South Africa, zircon can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and
