, and the resultant coated particles (aggregates of carrier-fine particle) are then floated. This technique has been tested for ores [6, 7] and coals [8]. Apart from the mineral processing field, flotation... J. Cent. South Univ.

of molybdenum and copper from their porphyry sulfide ores. One is the bulk copper- molybdenum flotation followed by separation, which has been widely used in several large-scale mines such as Dexing... Tables 1 and 2, copper, molybdenum, gold and silver are main metal elements meriting flotation recovery from the porphyry ores. Furthermore, copper and molybdenum minerals are primary sulfide ores......
of ores are processed by flotation each year worldwide[6-7]. Owing to the limitation of sources and supplies of mineral raw materials and the need to treat ores of lower grades, increasing fineness... for the concentration of iron ores and two classes of amines are used in plant practice of cationic reverse flotation of iron ores: ether monoamine and monoamine. A combined quaternary ammonium salt was used......
of the flotation pulp with 25% concentration was accomplished in a 5 L laboratory- scale ultrasonic bath. The total preconditioning time was 10 min, including activation for 5 min with copper sulphate (50 g/t) and subs- equently for another 5 min with sodium isobutyl xanthate (SIBX) (80 g/t) as a collector and polypro- pylene glycol (100 g/t) as a frother. Flotation experi- ments were conducted......

with high abundance, and its existence can influence the flotation results of sulfide copper ores. Therefore, it should be comprehensively investigated in order to improve the floatation effects... in the purification of copper ore, namely flotation and leaching, which are applicable for sulfide copper ore and oxidized copper ore, respectively [4]. Most copper (about 80%) in the world is obtained......
