Shaking tables are one of the oldest gravity separators in the mineral processing industry capable of handling minerals and coal of 0 2mm Shaking tables are rectangular shaped tables with riffled decks across which a film of water flows The mechanical drive imparts motion along the long axis of the table perpendicular to the flow of the water.
In the present study sample was taken from a tailing pond of an operating coal preparation plant was cleaned using an Enhanced Gravity Separator to produce a clean product of low ash content.
Gravity separation is the most effective method for processing ore and coal such as gold tungsten and tin It is also commonly used to recover rare rocks ilmenite rutile zircon monazite coltan and coltan and non ferrous metal minerals also used for sorting coarse grained inlays and a few fine grained hematite ores and manganese ore.
Gravity separation is a important mineral recovery method and has been the main beneficiation sector used in gold mining plants alternatively ahead of other processes such as flotation and cyanidation Gravity separation is an environmentally friendly beneficiation method that relies on water flow and gravity to separate target value minerals and gangues.
