Sand Processing Plant The sand plant reserve came from a old stream bed, that had a 20 to 30 ft thick sand deposit in it. It was sampled and the lab testing revealed that there was less than 0.03% iro...
Sand Processing Plant
Initially, the sand was sent to attrition scrubbers at around 50% solids, to remove any clay material (Al2O3) that is typically found in stream sediment. The attrited sand was then sent to a agitated holding/conditioning tank, where flotation reagents and water were added. A 30% solids slurry was then sent to a series of froth flotation cells where the silica dioxide was separated and the contaminating metals were removed, giving a 99.8% pure SiO2 product that use portable primary jaw crushing plant to manufacture high quality glass. The concentrate from this flotation process was the iron and other heavy metals, and the tailings were the high purity sand. The sand was de-watered on a series of cyclones, depositing their wet, sand in a stockpile to dry further in the hot desert sun. Sand from the stockpile was reclaimed by a bucket loader, mobile belt conveyor and feeders and sent to a rotary dryer to further dewater and the final product was loaded into rail cars and sent to the glass plant customer.
Make Glass Sand
Recycled aggregates, sodium carbonate and calcium carbonate are heated together to glass processing machine. The sodium carbonate lowers the temperature at which sand liquefies and the sodium carbonate makes the glass sturdier. Glass made from this mixture is referred to as soda-lime-silica glass, and most manufactured glass is made from this. However, other chemicals and dyes can be added to make "specialty" glass. Blue dye added to liquid soda-lime-silica glass makes blue-colored glass. Pyrex makes its glass containers by adding the chemical boron oxide. Glass is shaped into an end product by pouring liquid glass into molds or floating it on molten tin and allowing it to cool. Artisans still shape glass by "blowing" it. A hollow pipe is dipped into liquid glass, as the artisan blows through the pipe the glass expands like a balloon. The artisan can then shape the glass by twirling the pipe and controlling how much air he uses.
