Description
Technical field
The invention belongs to technical field of mineral processing, and in particular to a kind of sorting process of the hematite containing ferric carbonate.
Background technique
The dressing plant of processing lean hematite containing ferric carbonate mostly uses " coarse and fine separation-weight, magnetic, floating process integration " or adopts at present
It is sorted with " the strong magnetic-floatation process of stage grinding, weak magnetic-", wherein flotation uses stepped-flotation separation.Wherein " coarse and fine separation-
Weight, magnetic, floating process integration " is the closed circuit grinding system that raw ore feeds an ore grinding after crushing and scalping is constituted, once
Overflow product granularity be -200 mesh contents 55%~60%, primary overflow product after thickness grading cyclone, thickness grading it is thick
Granule product is sorted through two sections of spiral chutes, obtains gravity concentrate, and spiral chute tailing is swept middle magnetic and throws tail, the middling ore regrinding of acquisition
Thickness grading cyclone is returned afterwards, and regrinding product granularity is -200 mesh contents 75%~80%；The fine particle product of thickness grading is fed
Weak magnetic machine, weak magnetic tail feed strong magnetomechanical and are sorted, and the mixed magnetic essence that weak magnetic essence and strong magnetic essence are constituted first uses direct reverse flotation technique
Carbonic acid iron content is reduced, then is sorted using reverse floatation process, the flotation concentrate and gravity concentrate of acquisition constitute comprehensive concentrate,
Flotation tailing and strong magnetic tail mine sweep middle magnetic tail mine and constitute comprehensive tailing, and the technique existing greatest problem in the application, is when original
When mine property fluctuates, increases chats amount to ensure the grade of comprehensive concentrate and comprehensive tailing, after causing middling ore regrinding, regrind production
Product granularity is thicker, and chats amount further increases after middling recurrence, forms vicious circle and the chats amount of factory is respectively selected gradually to increase mostly
Add, it is some to reach 200% or more when selecting factory's maximum generally 100%~150%, considerably increase the production cost for selecting factory." the stage
Strong magnetic-the floatation process of ore grinding, weak magnetic-" is the closed circuit grinding system that raw ore feeds an ore grinding after crushing and scalping is constituted
System, primary overflow product granularity are -200 60% or more mesh contents, and primary overflow product feeds one section of weak magnetic machine, one section of weak magnetic tail
It feeds one section strong magnetomechanical to be sorted, the mixed magnetic essence that a weak magnetic essence and the last one magnetic essence are constituted feeds two sections of closed circuit grinding classifications and makees
Industry, secondary grinding graded operation product feed two sections of weak magnetic machines, and two sections of weak magnetic tails feed two sections strong magnetomechanical and sorted, two weak magnetics
Essence and the last two magnetic essence constitute two mixed magnetic essences first use direct reverse flotation technique reduce carbonic acid iron content, then using reverse floatation process into
Capable to sort, the flotation concentrate and gravity concentrate of acquisition constitute comprehensive concentrate, and flotation tailing and strong magnetic tail mine sweep middle magnetic tail mine composition
Comprehensive tailing, existing greatest problem is that flotation operation treating capacity is larger to the technique in the application, and production cost is higher.Both
Technique is common the problem is that floatation process is complicated, and flotation will carry out respectively foam and underflow after direct flotation to mine
Reverse flotation needs 8 sections of flotation operations, while flotation operation higher cost altogether, in addition when floating to the fluctuation of middle carbonic acid iron content, flotation
Operation is unstable, considerably increases the production cost for selecting factory.
