Metals are. usually extracted from ores using a combination of heating and reduction with carbon in the form. of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need. to be extracted by a process called electrolysis.
Hydrometallurgy is concerned with processes involving aqueous solutions to extract metals from ores. The first step in the hydrometallurgical process is leaching, which involves dissolution of the valuable metals into the aqueous solution and/or a suitable solvent.
The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.

The abundance of the ore in the Earth's crust. The mining costs. The energy costs in the process of extracting the metal from its ore. The demand for the metal.
The process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore. Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free state, the preliminary chemical treatment may be necessary.

The process of metal extraction from ore is dependent on the reactivity of the metal. Highly reactive metals are extracted by electrolysis. In order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum.
Extracting iron from the ore. Think about: Loss of landscape due to the size of the chemical plant needed. Noise. Atmospheric pollution from the various stages of extraction. For example: carbon dioxide (greenhouse effect); carbon monoxide (poisonous); sulfur dioxide from the sulfur content of the ores (poisonous, acid rain).

Extraction Process of Aluminium from Bauxite Ore. Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.
The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the “important” element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore; Since most minerals are not pure metals, further separation methods are required.
Iron Extraction Process In the blastlargely because of the amount of electricity used up in the extraction process Aluminium ore is ... To Extract Metal From Its Ore.
Extracting metal low in activity series:- The metals low in the reactive series are very less reactive. The oxides of such metals can be reduced to metals by heating alone e.g. mercury is obtained from its ore, cinnabar (HgS), by the process of heating.Extraction of metal using Heat is called Pyrometallurgy.
