· How long silica dust stays in the air is a combination of factors such as particle size distribution, wind direction, wind speed and turbulence. It is not based on one factor, but multiple of factors which differ from one scenario to the other. Silica dust is an atmospheric contaminant that is emitted from different sources.

 · In plants where silica flour is to be produced, drying is often necessary. Drying is done in rotary, oil or gas fired dryers. Dry grinding to minus 100 or minus 200 mesh is done in Mills with silica or ceramic lining and using flint pebbles or high density ceramic or porcelain balls. This avoids any iron contamination from the grinding media.

Silica gel and calcium chloride have different ways to remove moisture from the surrounding environment. Silica gel does it by adsorption, which means that the water molecules adhere to the surface of the silica gel. The silica gel is a very porous component with a high number of voids that may contain water when needed.

Economics questions and answers. Suppose Spain is currently producing 90 units of wine and 10 units of cheese, but to produce 10 more units of cheese it must sace 30 units of wine. Further, suppose that Portugal produces 45 units of wine and 45 units of cheese, but to produce 10 more units of cheese it must sace only 10 units of wine.

Asia Pacific is the biggest manufacturer of automobiles in the world with an estimated production of million units in 2017. This makes Asia Pacific a significant market for precipitated silica.
