Manufacturing Processes

This report comprises a thorough value chain evaluation for Silicon Dioxide manufacturing and consists of an in-depth production cost analysis revolving around industrial Silicon Dioxide manufacturing.
 

Production from Quartz Mines

• The feedstock for this method is naturally occurring quartz ore or silica sand. This method of production involves several physical and chemical purification steps to obtain various grades of silicon dioxide. The process starts with mining, which involves extracting quartz from the earth through open-pit or underground mining techniques, depending on the deposit. The extracted raw quartz undergoes initial sorting to remove gross impurities, followed by crushing and grinding to reduce its size. After that, the quartz goes through a purification process to get rid of impurities by using the flotation technique, where chemicals help separate unwanted materials. It can also be purified by the process of chemical leaching, which uses special solutions to dissolve impurities. The process leads to the formation of pure silicon dioxide as the final product.
   

Production from Sodium Silicate (Precipitated Silica)

• The feedstock for this method includes sodium silicate solution and sulfuric acid. This method of production involves the acidification of a sodium silicate solution to obtain synthetic silicon dioxide, often referred to as precipitated silica. The process starts by mixing a sodium silicate solution with sulfuric acid. When the acid is added, it reacts with the sodium silicate, causing a chemical change that produces silicon dioxide. Alongside the silicon dioxide, this reaction also creates sodium sulfate and water as byproducts. After precipitation, the silicon dioxide slurry is filtered to separate the solid product from the sodium sulfate solution. The filter cake is then washed to remove soluble salts (primarily sodium sulfate), followed by drying (e.g., spray drying or fluid bed drying) to obtain pure silicon dioxide as the final product. The dried product may then undergo further milling or granulation depending on its intended application.
