The technology of ore concentration characterized with lack of conventional multi-chamber hydraulic classifiers was put into operation at Etykinskaya concentrating plant for ores containing 0.011 percent of tantalum. Usage of hydrocyclones and spiral classifiers in combination with screw-type separators allows to decrease substantially number of used table concentrators, to increase metal extraction in roughing concentrate by two times and to decrease water consumption by three times.
