Bauxite proppant, also known as ceramic proppant, is an engineered material used in hydraulic fracturing (fracking) to enhance the extraction of oil and natural gas from unconventional reservoirs. The most common proppant is sand, but there is growing interest in engineered proppants. Engineered proppants are made from ceramics, typically derived from bauxite, offering advantages such as uniform size and shape, as well as high strength. The ability to strictly control particle size maximizes porosity, thereby maximizing the extraction of natural gas. Sintered bauxite proppants can be widely used in deep wells and high-pressure oil and gas reservoir fracturing treatments. Using high-quality bauxite as the main raw material, it is crushed, finely ground into powder, mixed with various additives, repeatedly kneaded, granulated, polished, and sintered at high temperatures to form the product. The product features high compressive strength, low density, sphericity, good roundness, high smoothness, and strong conductivity. What role does bauxite soil play in making proppant for petroleum fracturing?
