Jun 20, 2010· Extraction of Metals. You have learnt about the reactivity series of metals. Having this knowledge, you can easily understand how a metal is extracted from its ore. Some metals are found in the earths crust in the free state. Some are found in the form of their compounds. The metals at the bottom of the activity series are the least reactive.

50.5 EXTRACTION OF METALS METALLURGYChemistry
The chemical methods are suitable for reduction of compounds of metals which are in the middle of the activity series. 3. Autoreduction. Certain metals are obtained from their ores roasting without using any reducing agent. For example, mercury is directly obtained by roasting its ore cinnabar HgS in air.

Zinc is a metal found in the middle of the activity series
The metals found in the middle of the reactivity series are extracted by the reduction of their oxides with carbon, aluminium etc. So, in order to extract zinc metal from zinc carbonate, zinc carbonate is first converted into zinc oxide. Zinc carbonate calamine ore is heated strongly in the absence of air to obtain zinc oxide and carbon dioxide. This process is called calcination.
