Frac sand gets its name from its use in hydraulic fracturing ("fracking"), a completion method used by oil and natural gas companies to produce natural gas, natural gas liquids, and oil from unconventional, low permeability reservoirs such as shale. Basins with high frac sand demand include the Permian Basin, Eagle Ford Shale, the Mid ...
Sand and Gravel Processing | Equipment, Flow, Cases
Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away. The more resistant quartz eventually is ground down in ...
PROCESSING OF MONAZITE SANDS (Journal Article)
A process is described for recovering thorium, uranium, and rare earth values from monazite sand. The monazite sand is first digested with sulfuric acid and the resulting "monazite sulfate" solution is adjusted to a pH of between 0.4 and 3.0, and oxalate anions are added causing precipitation of the thorium and the rare earths as the oxalates.

Die Casting vs. Sand Casting – What's the Difference?
When fully solid, the sand can be removed via water jets, vibration, or other methods until the final part is unearthed. It is necessary to do some post-processing in sand casting such as polishing/sanding/excess metal removal, as this procedure does not conform to the mold as accurately as other casting methods.
