Based on carried out laboratory investigations and pilot testing there has been developed the technology of phosphate-bearing ores concentration of Oleniy Ruchey deposit with maximum recovery of two concentrates – apatite and nepheline. Environmental safety requirements were observed.
Studies on the enrichability of platinum-metal ore samples from the Pansky massif of the Kola Peninsula were carried out. A flotation enrichment technology with separation of platinum group elements (PGE) into the collective sulfide concentrate was developed. Using phosphate-type flotation agents the concentrate with copper content of 7.32%, nickel content of 5.04% and PGE content of 130.49g/t was obtained with recovery of 85.3, 70.9 and 76.5% respectively. Application of modular concentrating plant for development of hard-to-access deposit of platinum-metal ores is proposed.
