Description:

Under its program of advancing minerals technology, the federal Bureau of Mines developed a laboratory apparatus for continuous separation of minerals according to their dielectric properties. The unit consists of a rotating wire grid drum electrode and a fixed curved wire screen electrode positioned 3 mm apart. By applying high voltage across the electrodes that are immersed in a dielectric fluid medium, a high-gradient electric field is produced. The high- dielectric constant minerals are attracted and conveyed through the separator by the rotating drum electrode, whereas the low-dielectric- constant minerals settle through the fixed electrode. In typical tests, a sample of Montana chromite ore containing 43 pct chromite was concentrated to 72 pct chromite with 90 pct recovery. [Description provided by NIOSH]
