2014-11-15  Foundry sand (FS) is a by-product from the metal alloys casting industry with high silica content. Silica sand is bonded with clay or chemicals, and is used for the material casting process. Foundries recycle the sand many times, and when the sand is no longer recyclable, it is disposed of; this is called foundry sand.
