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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
