Abstract Beneficiation of low grade ore is of critical importance in order to meet the growing demand for coal and mineral industries But low grade ores require fine grinding to obtain the desired liberation of valuable minerals As a result production of fine particles makes the beneficiation process difficult through conventional gravity separators Hence alternative
The Mineral Jig Concentrator is a simple gravity separation metallurgy machine as it s essentially an open tank filled with water with a slightly inclined screen at the top and provided with a spigot on the underside for drawing off the concentrate Rectangular gold jigs are made of either a single 1 jig cell as stand alone or a series of cells organized in modules of
