By using only heat, all metals may be extracted from its ore - that is, unless you use electrolysis.

What is the extraction of metals?
First you mine the ore (typically oxides or sulfides of the desired metals), then you crush the ore, then you smelt the ore in a furnace. Some metals like aluminum must be extracted from the ore electrolytically instead of by smelting.
How are the very reactive metals high up in the reactivity series extracted from their ores?
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
Is ore extracted from a mineral or a mineral extracted from an ore?
An ore is a rock or mineral from which a valuable metal can be obtained through refining processes.
What two processes are used to extract metals?
There are 3 means of extracting metals that are used more than any others and they are: Reduction with carbon: An ore of a metal which is less reactive than carbon is heated with carbon and the more reactive carbon will separate the metallic element from its ore e.g extraction of Iron in a blast furnace Electrolysis: An electrical current is passed through a solution of the metal ore and the metal is split from its ore and collects at an electrode, this is done for metals more reactive than carbon Extraction by other metals: As some metals are more reactive than the other this can be used to split up the metallic ore, an example of this is the extraction of Titanium which involves the use of several other more reactive metals.
When a mineral deposits classified as an ore?
An ore is a portion of a mineral deposit that can be economically extracted at the present time. A mineral deposit is a concentration of naturally occurring material that is potentially economic to extract.
What metals can be extracted from bauxite?
Aluminum is extracted from bauxite ore.

What metal can be extracted from bauxite ore?
Bauxite contains aluminum oxide, from which aluminum metal is refined.
Why were gold and silver among the first metals to be discovered?
they are so unreactive, they do not need to be extracted from their ore.
How are the very reactive metals high up in the reactivity series extracted from their ores?
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
How is a metal made?
Metals are extracted from their ore through chemical reaction. Iron ore is an oxide of iron. The oxygen is removed from the ore by heating carbon with the ore to create molten iron and Carbon Dioxide.
How is calcium extracted from its ore?
its extracted
When is a mineral classified as an ore?
Minerals and groups of minerals can be classified as an ore when they contain a sufficient amount of desired material, most times metals, to be extracted and processed feasibly.
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.
Is ore extracted from a mineral or a mineral extracted from an ore?
An ore is a rock or mineral from which a valuable metal can be obtained through refining processes.
How is bronze extracted from its ore?
Various metals were in use in the Bronze Age. The name given by archaeologists to the period comes from the fact that bronze was the most widely used metal, but people also used copper and tin. Gold was used for decorative items and towards the end of the Bronze Age Iron was also widespread.
How was copper probably first extracted from its ore?
Copper was one of the first metals to be discovered, possibly by anchient potters whose furnaces were hot enough to produce copper from the ore malachite.
