 — Different materials possess different magnetic properties by which they may be separated. Figure 9.1a shows that when a magnet is placed close to an iron ball and a ceramic ball, the iron ball will be attracted to the magnet and the ceramic ball will not. Figure 9.1b shows that when a magnet placed close to a group of mixed tiny iron and ceramic …

The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N a O H will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical method.
