It is generally recommended that green sand be preceded by a 12 inch anthracite cap to filter any precipitated iron particulates before the green sand. In order for greensand to retain its adsorption and catalytic oxidation capabilities for iron and manganese removal, the media must be regenerated with permanganate or chlorine.
To better control this deadly dust, OSHA updated its crystalline silica exposure limit, making compliance much more difficult. Below you'll find articles that explain the ins and outs of the new rules, the best silica dust control methods, and what you need to do to become compliant.

Sep 14, 2012· Titanium Thermite Calcium Sulfate ... The silica isn't worth the effort needed to remove it, but the CaCO3 is easy enough to destroy with a treatment in acid. As a bonus, by using sulfuric acid I make more of my desired reagent!
Round sand and round grain iron oxide maximizes the possibility of obtaining that objective because a round shape minimizes surface area. Foundry technicians are encouraged to inspect SphereOX under a microscope and compare it to competitive iron oxides or any other proprietary foundry sand additive.
Silica: Sandlike substance found in areas of volcanic or desertlike areas. It is usually bound to calcium or magnesium and forms very hard, virtually insoluble deposits on surfaces. Water borne silica can build up on the hair, causing the same effect as calcium dryness, dandruff, weight, and hair loss.

Abrasive blasting uses compressed air or water to direct a high velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for painting. Abrasive blasting is more commonly known as sandblasting since silica sand is commonly used as the abrasive, although not the only one always used.

Once the cast has hardened, workers lift it from the sand mold and brush away any remaining sand. The relatively small granule size of silica sand is also ideal for filtration. It helps keep the water in swimming pools clear and removes harmful waste in sewer treatment plants. Brick manufacturers mix sand with clay to form their products.
