Zinc - The Essential Chemical Industry

In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often . using bacterial action. The bacteria used thrive at temperatures up to ca 320 K, and produce weak zinc solutions that are concentrated for electrolysis using solvent extraction.

BBC - GCSE Bitesize: Methods of extracting metals

Metals are very useful. Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. Copper is easily extracted, but ores rich in copper are becoming more difficult to find. Aluminium and titanium are.
