  • Developments in the physical separation of iron ore

    01/01/2015· Based on the magnetic susceptibility values in Table 91, iron ore can be divided into two groups, namely, strongly magnetic iron ores, that is, magnetite (724% Fe), and weakly magnetic iron ores (oxidized iron ores), that is, martite (700% Fe), hematite (700% Fe), specularite (700% Fe), limonite (5714–5989% Fe), and siderite (482% Fe) While magnetite is naturally suitable forWhen the grinding particle size is greater than 02mm, most iron ore magnetic separation plants usually use one stage grindingmagnetic separation; When the grinding particle size is less than 02mm, twostage grindingmagnetic separation is adopted; If qualified tailings are separated in the rough grinding stage, the iron ore magnetic separation plant should adopt the stage grindingmagneticSeparation process of iron ore,iron ore magneticFlotation is more to separate fine to particulate magnetic iron ore (particle size <002 mm) Gravity separation and magnetic separation are mainly used to separate coarsegrained and mediumgrained weakly magnetic iron ore (20~2 mm) During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation ofIron ore beneficiation technology and process,gravity and
