    Extracting Metals by Reduction

    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.
