Use a two-stage low-intensity and high-intensity magnetic separation process to remove magnetic minerals in feldspar ore to the maximum extent. Low-intensity magnetic separation can remove magnetite (Fe3O4), and high-intensity magnetic separation can remove hematite, limonite, ilmenite (Fe2O3)

The traditional process to extract aluminum from ore involves two major processes. The Bayer process extracts alumina from bauxite via a chemical process and is usually done at the mine site. Pure alumina is exported to a smelting operation. The Hall-Héroult process uses electricity to de-oxidize alumina into aluminum metal.

Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process.
