There are three basic ways of treating metallic ores in order to extract their metal content. Pyrometallurgy is the treatment of metals and their ores by heat. Pyrometallurgy includes Roasting, which is the heating of ores in air or heating it with a reducing agent such as carbon (coke) or carbon monoxide. Pyrometallurgy is the oldest extractive process. In early day Nevada, carbon was obtained from pinyon pines, juniper trees or sagebrush. The wood was collected and heated in ovens which resembled beehives and these ovens became the "Beehive Ovens" found today near numerous old mining camps.
The second basic way of treating metallic ore is electrometallurgy. In this method the metals are processed using electricity such as electroplating and electrorefining. Electric arc furnaces are used to make steel. Electrometallurgy is used when very high purity metal is needed.
The third basic way of treating metallic ore is hydrometallurgy. This is a wet process as the name implies, where reactants are used in a water solution. This method has not been used on an industrial scale due to the high costs involved. However, as the concentration of desired metal becomes less in the ores mined, the wet processing of the more valuable metal ores becomes more feasible

Name three general methods for extracting a metal from its ore?
The three method generally used to extract metals from ores are dependent on their reactivity. The first method is electrolysis, which is used for metals like aluminum and magnesium that have a high reactivity. The second is extraction by reaction with either carbon or carbon monoxide, which is used for less reactive metals like iron, lead and zinc. The third and final method is the use of hydrogen and this method is used for unreactive metals like gold, silver and copper. The third method is used in a variety of ways as many of these metals don't need to be separated from their ores but chemical reactions may be required to remove other contaminant materials.
How can carbon be used to extract a metal from its ore?
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
What method is used to extract magnesium or aluminium from their ores?

Why metals and their ores are so important to mankind?
Many of the metals that humans use come from ores. For example the iron used to make steel comes from the the mineral hematite, lead for batteries is produced from galena, and the magnesium used in vitamins comes from dolomite. Ores of these useful metals must be extracted from Earth in a process called mining.
How are metals separated from ores?
smelting is used for sulfide ores. Iron ores require a blast furnace. aluminum ores require high temperature electrolysis. etc. it varies by type of ore and metal.
Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
What are the uses of ORe?
Ore, as in rocks which contain sufficient metal to extract and it is economical to do so. Ores include bauxite, a copper ore. Ores can be used to extract precious metals which in turn can be used for electrical wiring, in the case of copper or as a catalyst, in the case of Haematite, Iron ore (the haber process).

How minerals recovered or extracted from their ores?
The methods used to extract minerals from ores vary; each ore has its own suitable method(s) of extraction. For example, iron can be extracted from its ore through the blast furnace method, while more reactive minerals (such as aluminum) may need to be extracted through electrolysis.
Why is electrolysis used to extract certain metals?
Electrolysis can be used for the following purposes:Electroplating a baser metal with a more attractive metal. e.g. electroplating brass with goldRefining of impure metals. e.g. to remove impurities from copperElectrometallurgy - to extract metals from their compounds
Hi Does anyone know why different metals have different uses apart from the fact that they have different properties?
There are two parts to it: Supply -- how common is the metal? How easy is it to extract from its ores? Is it concentrated in a few locations or is it widely distributed? Demand -- what's it used for? Will other metals work instead, or does it have specific properties that are required?
How and why are metals such as aluminium and iron recycled?
The metals are collected and then melted at high temperature. They then have any impurities scraped off the top of the container of molten metal. The pure molten metal is then poured into casts and cooled. The blocks of metal can now be used again. It is cheaper and less environmentally damaging to recycle metals rather than extract them from their ores, in the ground.
