Extracting Metals: Process, Meaning & Methods
The reactivity of a metal largely determines the method of extraction. Highly reactive metals like potassium are typically extracted by electrolysis, while less reactive metals like iron are extracted via reduction. In traditional methods, extracting metals involves three key procedures - concentration, reduction and refining.

A New Way of Extracting Copper
The MIT researchers found a promising method of forming liquid copper metal and sulfur gas in their cell from an electrolyte composed of barium sulfide, lanthanum sulfide, and copper sulfide, which yields greater than 99.9 percent pure copper. This purity is equivalent to the best current copper production methods.

What is the common method of extraction of copper from its ore?
The common method of extracting copper from its ore involves a series of steps: 1. Concentration of Ore: This is done by froth flotation. Sulphide ores of metals are usually concentrated by froth floatation process. In this process, the powdered ore is mixed with water and a little pine oil which is a foaming agent. It is then vigorously agitated by blowing air through it.
