Description
Technical field
The invention belongs to mineral separation technical field, and in particular to one kind is combined using falcon centrifugal reselections with flotation
Technique recycling wulfenite method.
Background technology
Molybdenum is a kind of important rare metal, and tool has been widely used：With China's expanding economy, to bases such as steels
The demand of material is more and more, production various steel alloy, cast steel, tool steel and stainless steels etc. is widely used in, to strengthen steel
Intensity, toughness and corrosion resistance；Molybdenum oxide and molybdate are the excellent catalysts in chemistry and petroleum industry；As molybdenum is other
The application of alloy field and chemical field also constantly expands, also increasing to the demand of molybdenum, therefore improves the ore dressing of Molybdenum Mine
Level, improves the comprehensive utilization ratio of Mo resource, provides high-quality molybdenum product more, keeps economic sustainable and stable development to have in China important
Meaning.Present molybdenum is mainly what is extracted from sulphide ore, but oxidizing molybdenum ore is also the important sources of molybdenum, and wulfenite is also known as molybdenum lead
Ore deposit, yellow lead ore, are the important sources for extracting molybdenum, and since it is than great, native floatability is poor, commonly use gravity treatment or sulphur
Change flotation to be sorted.But though traditional gravitational separation equipment such as spiral chute, shaking table etc. can effectively recycle larger particles ore deposit
Stone, is but difficult to recycle the smitham in ore, causes recovery rate in ore-dressing low；Traditional sulfide flotation method, can only also sort can
The good wulfenite of buoyancy.Therefore in order to improve the dressing level of wulfenite, accelerate the utilization of such ore, just have very much
Necessity researches and develops a kind of ore-dressing technique of more efficient wulfenite.
The content of the invention
The present invention's is to provide a kind of technique recycling wulfenite being combined using falcon centrifugal reselections with flotation
Method.
The purpose of the present invention is realized by following proposal：
1. raw ore is milled to the fineness that -0.074mm accounts for 70%~80% so that wulfenite is dissociated with gangue mineral；
2. use falcon centrifugal ore separators in recoil water flow for 2600~3200ml/min, 220~300g of centrifugal force
Under conditions of sorted, obtain wulfenite gravity concentrate；
3. falcon centrifugal reselection Tailing thickenings are dehydrated to the concentration of mass percent 30%~35%；
4. in terms of centrifugation tailing per ton, 260~500g sulfuric acid cleaned mineral surfaces, 2~4min, 1500~3000g sulphur are added
Change sodium activation 3~6min of wulfenite, then add 100~250g of collecting agent isoamyl xanthate and foaming agent 730A40~50g
1~2min of effect carrys out flotation wulfenite, scrapes foam and obtains wulfenite flotation concentrate.
Advantages of the present invention and technique effect：
The wulfenite of Li Du≤10 micron can be more effectively recycled using centrifugal ore separator falcon, and flotation can return
The wulfenite of 10 microns of granularity ﹤ is received, the combination of both can greatly improve the rate of recovery of wulfenite.
