The multi-purpose use of carbonatites from the Tikshozero massif of the ultramafic-alkaline rock and carbonatite formation is assessed geologically, technologically and economically. General geological data on the structural characteristics of the Tikshozero massif and the carbonatite complex are presented. The results of the technological study of apatite-bearing carbonatites, carried out to estimate their dressability, are discussed. Several schemes, developed to produce apatite and calcite concentrates, were tested. The authors infer that high quality apatite and calcite concentrates can be produced by an integrated approach to dressing schemes, using flotation and magnetic dressing methods. Technical and economic macrocalculations of the integrated waste-free use of Tikshozero carbonatites were made.
