the extraction of metals from their ores flowchart
Native metals are metals found in a pure form. Most metals are actually found combined with other elements, as compounds in ores. These metals must be extracted from their ores before they can be made useful. Highly reactive metals, such as titanium, require complicated extraction which can increase the cost of the pure metal.

Extraction of Metals - Methods of Extraction of Metals ...
Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.Get Price
