Research Status of Flotation Separation Technology of Siderite in Iron Ore
In order to study the adverse effects of siderite on the separation of iron ore,aiming at the problem that the fine particles of siderite are difficult to separate from each other,the typical iron ore contain-ing siderite is taken as an example to summarize the research status of the separation technology of siderite in iron ore.From the perspective of mineral composition,dissemination characteristics,grinding properties,surface physical and chemical properties and floatability of siderite-containing iron ore,combined with the current situation of siderite separation,the adverse effects of siderite on hematite,quartz and other minerals in the separation process are analyzed.Aiming at the problems of easy mudding of siderite,difficult separa-tion of fine particles,and seriously affecting the grade and recovery rate of reverse flotation concentrate of siderite-bearing iron minerals,the research status of pre-flotation separation process of siderite is analyzed,the key of current siderite separation technology to solve the problems of siderite fine particle adhesion and difficult separation is summarized,and the research on pre-separation technology of siderite is prospected.
