Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied.

Reactive metals are extracted from their ores using electrolysis. Ionic compounds conduct electricity when molten or in solution. Metal ions and non metal ions are attracted to opposite electrodes.

When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound. Electrolysis Electrolysis is the most powerful extraction method.
