Guideline for Management of Respirable Crystalline

Silica or silicon dioxide occurs in two forms, either crystalline or amorphous. The most common type of crystalline silica, quartz, is found in most igneous, metamorphic and sedimentary rock. The potential for worker exposure to crystalline silica is widespread within the minerals mining and quarrying industry.

Impurities The Bauxite Index

The rule of thumb is that, on a weight basis, any mass of silica that reacts in the refining process will cause an equal loss of caustic soda, and an equal loss of alumina to the red mud in the De-Silication Product (DSP). Thus silica is a key determinant of any bauxite's economic value. Important impurities and their effects listed opposite.

How silicon is made material, making, history, used

Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. 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.

Ideally the silica has low concetrations of iron, aluminium and other metals. The silica is reduced (oxygen removed) through a reation with carbon in the form of coal, carcoal and heating to 1500-2000 C in an electrode arc furnace. The resulting silicon is metallugical grade silicon (MG-Si).

Jan 07, 2018Higher silica content generally leads to higher requirements of caustic soda when refining to alumina. According to The Bauxite Index, a rule of thumb is that any silica that reacts in the refining process will cause an equal loss (by weight) of caustic soda, and an equal loss of alumina to the "red mud" tailings.
