What is Silica Sand?

Silica Sand is quartz that over time through the work of water and wind has been broken down into tiny granules. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday items such as glass construction materials personal care products electronics and even renewable materials.

What is Silica Sand? Sources & Uses of Silica Sand - Civil ...

Silica Sand is actually a granular material. It contains quartz and minute amounts of coal clay. Sometimes it has minerals in it. People call it quartz sand too. Most importantly it is the industrial sand. Quartz over time turns into Silica sand gradually because of the influence of water and wind.

How to Process Silica Sand? - JXSC Machine

After silica sand gravity separation there will still some percentage magnetic minerals in silica sand so need to remove it by magnetic separator different magnetic minerals will use different gauss magnetic separator for removing iron need 1000 gauss for removing ilmenite and hematite need 8000-9000 gauss. Different usage of silica sand will request different percentages of magnetic minerals remaining in the final silica sand product.

What Is Silica Sand & How Is It Different From Regular Sand?

One of the most common uses of silica sand is in water filtration whether processing well water or filtering your tap water. Because of its uniform shape and size silica sand is an effective filtration bed that consistently removes contaminants from water. Also it does not degrade when exposed to acidic chemicals.
