3. Feed Ore properties. The physical and chemical properties of the ore have a significant impact on the jig gravity separation process. The density composition of the ore determines the selectivity of the material. The greater the density difference between light and heavy minerals, the higher the separation efficiency.

S. Gray, in Gold Ore Processing (Second Edition), 2016. Abstract. Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. …

Gravity separation is used in mineral processing to separate minerals based on differences in their specific gravity [23]. REEs are good candidates for the gravity separation method as they have relatively large specific gravities (4–7) and are typically associated with gangue minerals (primarily silicates) that is significantly less dense [1 ...

Then enter the hammer crusher for fine crushing so that the subsequent gravity separation process can be carried out. The finely crushed copper ore is collected into the slurry tank and then sent into the distribution barrel by sand pump for uniform mixing. 2. Gravity separation: 6-S small channel steel shaking tables

Thus, the gravity separation process is used for the concentration of hematite. Thus, the correct option is (B) hematite. Note: Calamine is an ore of zinc, chalcopyrite is an ore of copper and bauxite is an ore of aluminium. The gravity separation process is used for the concentration of heavier ores of iron, lead or tin. Thus, these ores ...
