100 Ton per day Hematite gravity processing plant in Malaysia

Dasen Mining developed a beneficiation flowsheet for this 100 TPD hematite processing plant in Malaysia. The ore contained hematite and magnetite, with quartz as the main gangue mineral. Differences in mineral grain size were a key consideration in process selection.

Iron Ore Beneficiation Approach

The ore contained both coarse and fine iron mineral grains. Dasen selected a combined process rather than relying on gravity separation alone.

After the first grinding stage, gravity separation recovered coarse concentrate and removed part of the coarse tailings. The flowsheet also included a second grinding stage, magnetic separation and reverse flotation to treat material requiring further separation.

The purpose of early separation was to remove material that did not need further grinding. This was a process design objective, not a measured energy-saving result.

For similar hematite ores, laboratory testing is needed to establish the grinding requirements and separation route. Equipment selection should follow the test results rather than capacity alone.
