Abstract

During practical production, siderite has an influence on flotation efficiency to hematite and magnetite. In flotation system of dodecylamine, this paper studied the flotation properties of single minerals such as magnetite, martite and quartz firstly. On this basis, the influence of siderite to flotation efficiency of martite-quartz and magnetite-quartz mixed ores was discussed. The result shows that siderite will seriously effect on the flotation efficiency of hematite (magnetite)-quartz mixed ores. Increasing the amount of starch will weaken the impact of siderite to some extent.
