Overview . Introduction: In gravity separation, the shaking tables (gravimetric tables, shaker tables) are the most widely used and efficient sorting equipment for fine ore separation. The shaking table beneficiation is not just applied as an independent beneficiation method. Still, it is often combined with equipment such as jig separators ...

The coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2 ...

The tippler was a device for emptying the coal from the skips into the coal processing plant. In 1953, a new screening plant was installed. Contamination of Acland coal with foreign material had been a source of concern to the mine's customers. The new plant ensured the production of cleaner, graded coal.

Most of the mines employ twostage processing plants, with the first stage processing the raw coal to yield an export product and the second stage reprocessing the rejects from the first stage at a higher relative density to produce a thermal coal for Eskom. There are also a growing number of small plants that only produce coal for Eskom.

Sensorbased sorting techniques offer the potential to improve ore grades and reduce the amount of waste material processed. Previous studies show that sensorbased sorting can reduce energy, water and reagent consumption and fine waste production by discarding waste prior to further processing. In this literature review, recent investigations of sensorbased sorting and the fundamental ...

Sorting coal using xray transmission sensors has been explored since 1972 by Jenkinson et al. Coal sortability is assessed using washability derived from dualenergy XRay transmission (DEXRT) system. Coal sorting is considered to be dry separation of coal that can be carried out before coal is send to the processing plant.
