Principles And Procedures Involved In The Extraction Of ...

Principles of Metal Extraction: Metals are found in the combined state in ores where they exist as positive ions. During the extraction of metals, the metallic ions must first be reduced to the corresponding metal atoms. This reduction process can be done electrolytically or by thermal or chemical methods.
