Sub-aeration cells, a section of which is shown in Fig. 32, consists essentially of a series of square cells with an impeller rotating on a vertical shaft in the bottom of each. In some machines the impeller is cruciform with the blades inclined at 45°, the top being covered with a flat circular plate which is an integral part of theTHE SEPARATION OF PYRITE AND ARSENOPYRITE BY,The efficient separation of pyrite and arsenopyrite by a cheap process such as flotation has long been recognized as a desirable technological goal for ores containing both minerals. A series of novel collectors, based on a different chemistry from conventional xanthates and similar surfactants, has been developed, which might lead to the separation of sulphide minerals with better selectivity and underIntroduction to Mineral Processing or Beneficiation,Advancements in technology have expanded the use of flotation for recovery of oxide minerals such as hematite, cassiterite, malachite, fluorite, and phosphates. The use of flotation for recovery of fine coal is also widely practiced. The flotation process begins with a modification of the surface properties of the desired mineral. The addition of surfactants renders the mineral surface hydrophobic (water-hating), so that the mineralFoams in mineral flotation and separation processes,,AB - Foam flotation is a process used worldwide to separate metallic and nonmetallic minerals from extracted ore.
