· 3. Beneficiation of lithium ores. The major techniques used in the beneficiation of lithium minerals are shown in a generalised flowsheet in Fig. 4, and include gravity separation (DMS), magnetic separation, and froth flotation. Sorting is also being recognised as a potential method in recent years.

· The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.

· 2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.
