Silica Sand Processing Plant
Silica Sand Processing
According to final application, the processing of silica sands is varying and complex. Various types of silica sand processing plant involved in the process. For most applications, silica sand processing aim to improve the properties of the sand, mostly by adjusting the grain-size distribution, by removing undersize and oversize material, and removing impurity materials in the sand or from the surfaces of the individual sand grains. Sands used in the manufacture of colorless glass are further processed by acid leaching, froth flotation or gravity separation to remove impurities. Most foundry sands are dried before delivery.
Silica Sand Washing Plant
Washing and size classification is the simplest and economic method of cleaning silica sand. In some of the very pure deposits that are void of heavy minerals, high amounts of clay and silt, and no surface staining, washing is sufficient to produce acceptable grade product. In the process, water is added to the sand and is generally pumped to a cyclone for desliming. The movement of the slurry passing through the pump and pipeline is sufficient to loosen the small amount of fines or clay that is in the ore body. Sand washing plant is an important silica sand processing plant.
