LiaoningInstituteof Geology and Mineral Resource, Shenyang 110032, China; 2. Shenyang Research Instituteof Nonferrous Metals, Shenyang 110023, China) ABSTRACT The ore nature and technologicalmineralogy characteristics of a certain andalusite ore in Liaoning have been studied. A combined flowsheet which include deslime, flotation, magnetic separation and acid treatment was employed. Qualified andalusite and magnetite concentrates were obtained.
