Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it ...

The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. At the refinery further crushing and/or washing may take place before the crushed bauxite is subjected to a grinding operation for final sizing before digestion.

However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose crusher or grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple.

process of separating valued minerals from the matrix rock. The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require

Step 1- Crushing process The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which helps to speed up the follow-up speed of the chemical reaction.
