The paper presents the laboratory experiments for concentrating muscovite mica from feldspathic pegmatites in high-intensity electric field. The experiments have been carried out on a roll type research electroseparator and a (0.16…0.4)mm sample. Four separation procedures were tested: 1) DC electrostatic separation with thermal conditioning of the sample; 2) AC electrostatic separation at ambient temperature; 3) DC corona separation using metallic-surface rotating electrode; 4) DC corona separation using dielectric-surface rotating roll. The best quality of mica has been obtained in the last procedure by a three stages separation experiment: 46.11% SiO 2 , 33.64% Al 2 O 3 and 11.1% (K 2 O+Na 2 O). In all four procedures the grade of mica concentrate fulfils the requirements of several industrial applications such as welding wires manufacturing.
