The reduction of occupational exposure to crystalline silica is a regulatory priority at the federal and state levels. 1 – 4 Silicosis, a fibrotic disease of the lungs, is an occupational respiratory disease caused by the inhalation and deposition of respirable crystalline silica dust. 5 Silicosis is irreversible, often progressive (even after exposure has ceased), and potentially fatal.

Chapter 07 - Precipitation Softening | SUEZ

The silica reduction is accomplished through adsorption of the silica on the magnesium hydroxide precipitate. If there is insufficient magnesium present in the raw water to reduce silica to the desired level, magnesium compounds (such as magnesium oxide, magnesium sulfate, magnesium carbonate, or dolomitic lime) may be used.

Mineral processing - Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
