Metallurgy Dalal Simplified ICSE Chemistry Class-10

(i) Dressing of the ore is an essential process in the extraction of metal from its ore. Answer: The ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing.

Bauxite ore dressing method

Bauxite ore can be divided into high alkali bauxite, high titanium bauxite or high iron bauxite according to the impurities contained in it. The process of sorting bauxite concentrates from bauxite ore is actually a process of removing gangue minerals and harmful impurities, separating high-alumina minerals and low-alumina minerals to obtain high-aluminum-silicon ratio concentrates.
