Description
Technical field
It is a kind of high efficiency flotation side for high-grade zincblende specifically the present invention relates to a kind of beneficiation method
Method.
Background technology
In the conventional process flow of lead-zinc ore floating operation, conventional method be by one roughing obtain part concentrate and
Mine tailing；Its mine tailing scans flow by the once above again, final to obtain the most concentrate for meeting grade requirement of technological requirement；
But in the case of mill head grade is higher, single roughing working load is higher, when bioaccumulation efficiency is relatively low for enrichment, while can increase
Plus follow-up mine tailing scans burden.Therefore provide and a kind of adapt to the mineral processing circuit that mill head grade is widely varied and be
It is necessary.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of beneficiation method, to adapt in mill head grade significantly
In the case of change so that roughing operation has concentration ratio higher, while improving the efficiency of whole flow process.
The technical solution adopted in the present invention is：In whole technological process, two-way open circuit roughing link is set, including
Roughing I and roughing II and link is subsequently scanned, specific method is, lead zine ores are by isolating lead and sulphur, into agitator
Carry out respectively activator size mixing sized mixing with collecting agent after the zinc sorting operation raw ore that obtains, 1. when zinc grade be 15.5~
During 17.5wt%, ore pulp >=2/3 enters zinc roughing II, and a concentrate after enrichment enters back into zinc roughing I and mixes with ore pulp≤1/3
Reprocessing obtains final concentrate, and the mine tailing of zinc roughing II enters subsequently to be scanned；2. as zinc grade >=17.5%wt, ore pulp >=1/2 is entered
Enter zinc roughing I, the mine tailing of zinc roughing I is mixed into zinc roughing II with ore pulp≤1/2, and concentrate part is all as final concentrate, zinc
The mine tailing of roughing II enters subsequently to be scanned.
The above-mentioned follow-up concentrate for scanning operation acquisition returns to a upper operation of correspondence technique；The mine tailing of single operation is routinely
Operation enters next operation, until mine tailing zinc grade≤0.7wt%.
Agitator distributes the pipeline that two tunnels are respectively configured gate valve I and gate valve II, and the flotation device of zinc roughing I is led to all the way,
The flotation device of zinc roughing II is led on another road；The flotation device concentrate outlet of zinc roughing II is respectively configured gate valve III and lock by threeway
Valve IV, gate valve III is connected to the flotation device of zinc roughing I by pipeline, and gate valve IV connects final concentrate.
When raw ore pulp grade is relatively low, setting gate valve I aperture is less than 1/3, and the aperture of gate valve II is more than 2/3, meanwhile, open lock
Valve III, closing gate valve IV realizes that zinc sorting operation raw ore, by the enrichment of zinc roughing II, enters back into the enrichment of zinc roughing I, improves enrichment
Than so as to ensure that zinc concentrate grade reaches technological requirement；
When raw ore pulp grade is higher, setting gate valve I aperture is more than 1/2, and the aperture of gate valve II is less than 1/2, meanwhile, closing gate valve
III, gate valve IV is opened, the operation concentrate of roughing II realizes that the operation of roughing I, the operation of roughing II are floating using open circuit directly as zinc concentrate
Choosing, the concentrate of output merges into zinc concentrate, by open circuit flows, improves the flotation speed of zincblende, realizes that metal recovery rate is carried
Rise.
The beneficial effects of the invention are as follows：Flotation process for mill head grade change, using shunting roughing and
After local open loop manner so that flow has stronger adaptability to mill head Grade change, and it is selected to improve high-grade
The flotation speed of raw ore.
Brief description of the drawings
Fig. 1 is shunting roughing of the invention and local open loop manner schematic diagram.
Each label is followed successively by figure：Agitator 1, flotation device 2, flotation device 3, gate valve I 4, gate valve II 5, threeway 6, gate valve III
