concentration or dressing of the ore the ore are usually obtained from the ground and therefore contained large amount of unwanted impurities, the elimination of these impurities from the ores is known as concentration. the concentration of it is done by the physical as well as chemical methods.
The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore from the gangue particles.

Dressing or concentration of the bauxite ore Bauxite is generally found as an impure form of aluminium oxide. The process which gives the ore such a physical form so that the gauge can be easily removed from it, is called dressing of the ore. It is done by hand picking, grinding etc.
The dressing of ore is also called concentration of the ore because it gradually increases the percentage of metal. In metallurgy, the concentration of ore is achieved in the following two methods. (i) Physicals Methods. Hand-picking is a traditional method
The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n
The correct option is D All of the above. The extraction of a metal from its ore involves mainly three stages. They are I) Concentration or Dressing. II) Extraction of crude metal. III) Refining or purification of the metal. Suggest corrections. 0 Upvotes.
Concentration of Ore Ore Dressing. Ore is a impure metal containing large amount of sand and rocky material. The impurities like sand, rocky materials, limestone, mica etc present in the ore is called gangue or matrix. The substance added flux to the ore to remove the matrix results in the formation of a fusible compound called slag.
