Which process is used for the concentration of Bauxite (Al2O3 ...

The process is repeated several times and the heater is moved in the same direction. At one end impurities get con-centrated. This end is cut off. In this way, the impu-rities are swept from one end of the bar to the other. By repeating the process, ultra pure metal of silicon, germanium etc are obtained. Fig. Zone Refining Process

Introduction to Mineral Processing or Beneficiation

The most common and notable example of this are precious metal values (gold, silver etc.) where the beneficiation process is applied directly on run-of-mine ores followed by the extraction of gold and in some cases silver as a relatively pure metal within the mineral processing circuit. 2.0 Processing Approach and Method

Beneficiation and mineral processing of bauxite and feldspar

i) Bayer process Bayer process is Hydrometallurgical processing to extract aluminum oxide (Al2O3) from bauxite ore. Bauxite is powdered prior to the start BAYER process. Aluminum oxide (Al2O3) from bauxite ore dissolve in caustic soda (i.e., Sodium hydroxide (NaOH)) and lime (Ca(OH)2). Iron oxide, silicon oxide (SiO2), and titanium oxide (TiO2), and other materials dont dissolve. As aluminum oxide is amphoteric, it dissolves in sodium hydroxide solution.
