Other articles where jigging is discussed: mineral processing: Gravity separation: In the process called jigging, a water stream is pulsed, or moved by pistons upward and downward, through the material bed. Under the influence of this oscillating motion, the bed is separated into layers of different densities, the heaviest concentrate forming the …

Jigging is essentially a cleaning process to separate particles of different relative densities. Usually the jig feed is narrowly sized, however the definition of settling …

Separation Process Principles with Applications Using Process Simulator, 4th Edition is the most comprehensive and up-to-date treatment of the major separation operations in the chemical industry. The 4th edition focuses on using process simulators to design separation processes and prepares readers for professional practice.

Such a choice is mainly due to the fact that Eddy current separation process is highly dependent on the size of the feed particles according to its separation principle. The magnitude of the repulsive forces depends on the specific conductivity, mass, morphological and morphometrical characteristics of the particles, and on the intensity …

Jigging Principles. Jigging uses a pulsation of a fluid at a given frequency and amplitude to induce a separation based on differential acceleration, hindered settling and consolidated trickling. For small particles, short pulsations are preferred to emphasize separation based on differential acceleration. Particles in a mixed pile before laying

Current research is aimed at developing methods of monitoring bed dilation to achieve automatic control of the jigging process; this has not yet been achieved. Jigs are the best all-round units for coarse gold separation in roughing service but good recovery is limited to gold grains larger than 100–150 μm in well-classified feed.

In practice, usually flotation reagents need to be added to amplify the difference in surface floatability of minerals. In principle, flotation process can separate various mineral materials and thus is the most commonly used mineral processing process. Magnetic Separation. Magnetic separation is the process in which separation …

It is found that despite some limitations of the technique, all the samples prepared for the experiments were successfully separated. The follow-up experiments were then carried out to further assess the separation of copper wire and rubber insulator. The effects of air flow and pulse rates on the separation process were examined.
