The most important iron ores are haematite (Fe 2 O 3) with up to 69.9 % iron content, magnetite (Fe 3 O 4) ... DSO ores with iron content of 58 % are produced. For magnetite ores, beneficiation is typically more complex with finer ore grinding and downstream DMS (Dense Media Separation) and LIMS (Low-Intensity Magnetic Separation) separation ...

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. Dense media separation is …

This literature review focuses on the various techniques used in the beneficiation of lithium minerals from hard rock pegmatite ores. Dense media separation and flotation are the main ...

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.

The most common flotation route used for the beneficiation of iron ores is reverse cationic flotation. This process is the major technique used to produce pellet feed fines at all Brazilian
