It is easier to obtain a metal from its oxide rather than its sulphides or carbonates because oxides are more readily reduced to metals compared to sulphides and carbonates.

Metals typically found in the middle of the activity series include iron, zinc, lead, and copper.

Yes, cinnabar (HgS) is an ore of mercury. When heated in air, cinnabar is converted into mercuric oxide (HgO). Further heating of mercuric oxide results in its reduction to mercury, the pure metal.

The oxides of metals low in the activity series are typically reduced to metals by heating alone. This process involves heating the metal oxide in the absence of air, causing the oxygen to be removed from the oxide and leaving ...

Separation techniques help in the extraction of metals from ores by selectively separating the gangue materials from the ore based on their differences in physical or chemical properties. This results in a concentrated form of the ore, which can then ...
