Metal ores are typically salts, such as oxides, carbonates or sulfides. Conversion of these ores into metals requires oxidation/reduction reactions. That's not always the case. Some early forays into metallurgy involved native gold (native meaning the metal is found in its elemental state in nature). Gold is relatively soft.

Metals are extracted from their ores. Each metal reacts differently with different substances. The extraction of any metal from its ore is dependent on the reactivity of the metal. Thus, the metals present at the bottom of the reactivity series versus those present at the top of the reactivity series follow different processes of extraction.. The following metals in the periodic table are ...

This procedure is most commonly used to extract magnetic ore from impurities. Two moving rollers operate, on which operators place the crushed ore. Here, the magnetic ore remains, and the rest of the gangue passes away. This process is highly used in the extraction of iron ore and is one of the fastest procedure types for this.

The process of extracting iron from its ore involves crushing the ore to a powder and then heating it in a furnace with a carbon source. The carbon reacts with the oxygen in the ore to create carbon dioxide gas, which leaves the furnace through the smokestack. The molten iron is then poured into molds to cool and solidify.
