The process reduces bauxite residue by a remarkable 30% by eliminating iron values while simultaneously recovering a higher alumina yield, reducing the total organic content from bauxite during the alumina refining. The process significantly enhances resource efficiency and curbs energy consumption during refining.
Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then removed, leaving the process liquid, termed "green liquor."

Common impurities found in gold ore include silver, copper, iron, and sulphur. These impurities need to be separated and removed through various refining processes to obtain pure gold. Refining Process Steps to Follow. The initial step in the gold refinery process involves the extraction of gold ore from the ground.
In the latest report of the engineers at Trollhattan, it is stated that the power consumption per ton of pig iron varies in proportion to the iron content of the ore. A poor ore and pig iron high in silicon and manganese require more power than a rich ore and pig iron low in silicon and manganese. This was also found to be the case in California.
In the smelting process, iron ore is heated, leading to the separation of iron from impurities. This iron-carbon combination forms the basis for the production of steel.
