Metal Winning: General Methods of Extraction and
Abstract. EXTRACTION comprises the various methods used to obtain and to consolidate metal from concentrates, ore, or some mixture, or from chemically purified mineral; sometimes the mineral may be first converted to a more amenable form. The procedure thus involves removal of remaining gangue, decomposition of the mineral if a compound, and ...

Extraction of Metals - Amar Ujala
2020-6-27 · Refining (contd) •To use grey pig iron, a preliminary refining process was necessary to remove silicon. The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough.
