Description
Technical field
The invention belongs to the exploitation of ultralow grade rock resource high-efficiency and associated minerals technical field of comprehensive utilization, and in particular to one
The beneficiation combined method method and system of kind synthetical recovery association iron Phosphate minerals.
Background technique
In the past 20 years, with industrial expansions such as automobile, petroleum, microelectronics, national defence, aviation and space flight, user is to steel
The requirement of quality and Composition Control is continuously improved, and causes clean steel production to become the core content of steel-smelting technology development, wherein phosphorus
The control of content is even more one of key factor.Many steel grades require w [P] less than 0.01% or 0.005%, and ultra-low phosphoretic steel then requires w
[P]≤50×10-6.Global iron ore price rises in recent years, forces the domestic development and utilization for paying attention to high-phosphorus iron ore, but high phosphorus
The ore dressing of iron ore and the expansion smelted with Low-phosphorus Steel kind and purposes are contradictory.
The molecular formula of fosfosiderite is FePO42H2O or Fe2O3P2O52H2O（P2O5=38.9%, Fe2O3=
43.8%, H2O=17.3%）.Iron black color, for the column crystal of red orthorhombic system.Hardness 3.8, density 2.8g/cm3.Gloss is in
It is glassy.Color is light red or light red purple.It is used for mentioning phosphorus.Structure has transparent columnar protrusions close to conglomerate, has curved
Bent joint, glossy there are also a kind of rust, quality is hard, often and bloodstone, phosphorus ore, siderite, magnetic iron ore association, and specifically
Appearance characteristics and associated minerals are close.Its grade of ore has 10%---70% etc..
It is achieved aobvious by using " throwing in advance useless " mode after grinding preceding fine crushing or even coarse crushing is entered to reduce production cost
The economic benefit of work.But the throwing of lump ore and lump ore is useless, primarily directed to the higher magnetic iron ore of grade, throws and removes recovery process
The country rock gangue of middle entrainment.For low-ore grade magnetic iron ore, massive ore, which is thrown to give up, can not make a large amount of gangue mineral abundant
Throwing removes, and is also easy to dish out valuable mineral, it is difficult to achieve the purpose that production cost is greatly lowered.And phosphate rock floating process,
Conventional phosphate rock floating processing temperature is 37C °, consumes huge, the heating boiler scale of construction of outfit by this condition flotation workshop thermic load
