USING REDOX REACTIONS TO OBTAIN PURE METALS

So many techniques!!!

The specific technique chosen depends on the mat al's reactivity and the availability of inexpensive reducing agents and energy sources. 

Electrometallurgy involves using an electric current to supply electrons to metal ions, reducing them. Pyrometallurgy involves treating metals and their ores with thermal energy (heat). Carbon and carbon monoxide are common reducing agents here. They provide electrons; metal ions are then reduced to form metal atoms. A more reactive metal can be used if neither of these reducing agents will do the job. Hydrometallurgy involves treating ores and other metal-containing materials with reactants in water solution.
