Metal Ore. Ore metals are extracted from country rocks during water–rock interaction, and sulfate is predominant over sulfide in the mineralizing fluids, which means that sulfide must be provided or generated by reduction at the site of deposition (Ohmoto and Goldhaber, 1997).

 · Metals are found in ore in the form of compounds with other elements. Metal extraction is the process of extracting metal from its ore. The techniques for extracting metals from their ores and refining them are referred to as metallurgy. There is no single procedure that can extract all of the metals.

Earth's crust contains some naturally occurring components called minerals in which metal compounds are found. Ores can be said to be those minerals from which metal can be economically and easily extracted. Metals are not always found in the free state. Metals like Potassium, Sodium, Calcium, Magnesium, etc are found in a combined state.
