Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
In the actual production, float purification can also be used, but the most commonly used method is gravity separation, magnetic separation and flotation application are used very rare. As a professional manufacturer of mineral processing equipment, Forui Machinery introduce to you a common chromite beneficiation process. 1.
magnetic separators. Dry magnetic separation is more controllable since the separation medium is air rather than water. Separating particles from one another is naturally ... gravity concentration to remove a magnetic stream that can ... entered the flotation circuit.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Starting with a mixture of any of the above minerals it may be determined whether or not they can be separated by high tension, magnetic, or gravity methods and whether any one, or a combination of "Electromagnetic Separation" methods is required. If the minerals appear in different columns they may be separated by high tension and/or magnetic methods alone.
Xinhai decided to adopted heavy medium primary, gravity separation-flotation- gravity separation combined process .Based on the fine grain of tin ore pulp and slow fall velocity, Xinhai adopted Xinhai centrifugal concentrator for roughing and discarded a large number of tailings.
Rare earth (RE) mineral deposits are typically processed using several different unit operations including flotation, gravity, magnetic and electrostatic separation techniques. Two of the most important beneficiation techniques for RE minerals are gravity and magnetic separation.

Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...
