Question

Explain extraction of metals. How are metals of medium reactivity extracted.​

Answer 1

Answer:

Conversion of metals ores into oxides:

So, ores found in the form of sulphide and carbonates are first converted to their oxides by the process of roasting and calcination. Oxides of metals so obtained are converted into metals by the process of reduction.

Elements: Lead; Gold; Copper; Iron; Magnesium...

Explanation:

Metals of medium reactivity level

Sulphides ores are converted into oxides by heating strongly in the presence of excess air. ... Carbonates ores are calcinated to eliminate carbonate and moisture impurities. Calcination is a process where the ore is converted into oxides by heating strongly in the presence of excess air.
