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.

In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise nonspontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.

Metal ores are generally oxides, sulfides, silicates (Table 1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 1 ). The ores must be processed to extract the metals of interest from the waste rock ...

: Geology Iron and its Ores. Perhaps the most useful feature of thermochemical equations is that they can be combined to determine Δ Hm values for other chemical reactions. For example, iron forms several oxides, including iron (II) oxide or wüstite (FeO), iron (III) oxide or hematite (Fe 2 O 3 ), and finally, iron (II,III) oxide or ...
