methods of extracting metals from ores

Ore | National Geographic Society

Metal is extracted from the crushed ore by one of two major methods: smel ting or electrolysis.Smelting uses heat to separate the valuable metal from the rest of the ore. Smelting usually requires a reduction agent, or another chemical, to separate metal from its ore. In the earliest smelters, the reduction agent was carbon in the form of charcoal.

Use of microbes to extract and deliver metals from ores - IdeaConnection

Introduction Isolating a metal from its ore is traditionally performed via smelting, where the ore is chemically reduced under high temperatures. This process works most efficiently in cases such as copper, where there is a high concentration of the metal in its ore, However some metals, such as gold, have low metal content in the ore, which makes traditional methods of refining less economical.
