Question

write the difference stage of obtaining pure metal from it's ore

Answer 1

The process of extracting a metal in pure form from its ore is known as metallurgy. The process of treatment depends on upon the nature of the ore, impurities, and the metal.
From the extraction point of view, the metals can be broadly classified into five categories.
Category I :Highly electropositive metals such as alkali metals are extracted by the electrolytic method from their molten/fused salts.
Category II :Electropositive metals such as alkaline earth metals are extracted by electrolytic method form their molten salt.
Category III : Reactive metals of high valency are extracted by reduction and electrolytic method.

Catagory IV :Heavy metals such as Fe, Co, Ni , Cu , etc . are extracted by roasting and reduction methods.

Catagory V :Less reactive metals such as Ag, Au, Pt, etc. are extracted by amalgamation or cyanide process.

The various process involved in the extraction of pure metals from their ores are :

Concentration or Benefaction of the ore

Extraction of crude metal from the concentrated ore

Refining of the crude metal.
