represented by vacuum flotation and electrolytic flotation [10−11] In the floc flotation, it is the formed flocs instead of individual fine particles that interact with air bubbles, avoiding the problem of low probability of collision and adhesion of mineral fines to air bubbles Hydrophobic flocculation is Table 2 shows a typical mass balance for an ultrafines flotation circuit Assuming that the chemical analysis of the slimes is essentially the same as the feed grade, the loss of phosphate in the slimes is equal to the mass rejection Table 2: Typical mass balance for Ultrafines circuit Analysis Circuit Overall % P 2O 5 Circuit OverallTHE USE OF COLUMN FLOTATION FOR THE RECOVERY The flotation mechanisms of molybdenite fines by neutral oils were investigated through microflotation test, turbidity measurements, infrared spectroscopy, and interfacial interaction calculations The results of the flotation test show that at pH 2−11, the floatability of molybdenite fines in the presence of transformer oil is markedly better than that in the presence of kerosene and diesel Flotation mechanisms of molybdenite fines by neutral oils
An effective approach for improving flotation recovery of
An effective flotation approach is proposed for improving the recovery of molybdenite fines from a finelydisseminated molybdenum ore To maximize the flotation recovery of molybdenum, process mineralogy of raw ore, contrast tests, optimization of operation conditions and particle size analysis were systematically investigated Process mineralogy suggests that in the raw ore, 6163% of Oil agglomerate flotation (OAF) process demonstrates an obvious superiority in improving the flotation recovery of molybdenite fines Furthermore, the flotation results of OAF process reveal that the dosage of transformer oil plays a critical role on the average size of collected mineral particles ( d 50 p ), agglomerates ( d 50 a ) and the molybdenum recoveryAn effective approach for improving flotation recovery of In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals In order to achieve this, comminution circuits usually consist of Challenges Related to the Processing of Fines in the
