Shaking tables have different effective recovery particle sizes to adapt to ores with different particle sizes. Shaker tables with a maximum feed particle size of 2mm are for coarse ores, 0.5mm for fine ores, 0.15 for slime. Gold shaker tables are often used for concentration. What we love: It has high separation efficiency;

Oil Refining and Products. Abdullah M. Aitani, in Encyclopedia of Energy, 2004 2.2 Crude Oil Processing. As a first step in the refining process, water, inorganic salts, suspended solids, and water-soluble trace metal contaminants are removed by desalting using chemical or electrostatic separation.This process is usually considered a part of the …

Centrifugal separators are also used during plastic manufacturing. They find great applications during PP, HDPE, and PVC polymer production. Similarly, these filters are used in minerals and ores production, pharmaceutical and biotechnology sectors, and during the production of non-fossil fuels, among others.

Gravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material into very small mass The resurgence of gravity concentration in mining has come about due to its …

13.5.3.4 Spiral Concentrator. The spiral concentrator is a modern high-capacity and low-cost device. It is developed for concentration of low-grade ores and industrial minerals in slurry form. It works on a combination of solid particle density and its hydrodynamic dragging properties.

Falcon concentrators as enhanced gravity separators have been developed for the sharper separation beneficiation of finely disseminated ores based on their specific gravity diferences. Falcon concentrators employed centrifugal force, which is many times improve the separation based on the gravitational force.

Gravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (e.g. air, water) etc ...

If the magnetic force acting on a particle is stronger than the gravitational force, then the particle will move toward the magnet. ... High intensity and high gradient magnetic separators. Oxidized iron ores are much more difficult to upgrade by magnetic separation, because of the low magnetic susceptibilities of their contained iron minerals ...
