· Generally, columbitetantalite concentration begins with gravity concentration; this is followed by additional gravity and magnetic separation steps to upgrade the concentrate (Lv et al., 2012, Yuan et al., 2015). However, concentration by gravity machines becomes less efficient as the particle size reduces to finer size.

Magnetic Disc Separators. The Magnetic Disc Separator (MDS) is a sorting system equipped with up to three independently working discs which generate magnetic field strengths up to 14,000 gauss. The high magnetic forces that the MDS generates are able to extract paramagnetic particles from a freeflowing, dry product stream (100μm – ).
Trommel scrubber is a kind of equipment used to wash ores in industries such as ferrous metal, nonferrous metal, metallurgy and mining. The washing process is: Add clear water to such equipment and remove impurities such as mud and sand of the raw core dissolved in water. After such washing process, the ores can meet technological requirements.

Jun 05, 2020 · The early mining barite ore is mostly highgrade ore, which is usually separated by the lowcost and low technical handpicking or gravity separation process. However, with the low grade of barite ore and the complex ore properties, magnetic separation, flotation and combined barite mining processes have been widely used in barite mining.
