Description
Art
The present invention relates to a kind of beneficiation method, belong to gravity treatment-magnetic separation-flotation-gravity treatment beneficiation combined method method, it is especially a kind of
The beneficiation method of low-grade polymetallic ore.
Background technology
Present beneficiation method has a lot, there is flotation, magnetic separation, gravity treatment, electric separation etc.；General beneficiation method is all existed
Various the problem of, otherwise high cost, otherwise the rate of recovery is low, particularly low-grade polymetallic ore, because grade is low, and mineral
Composition is complicated, is often discarded by each mine；The metal easily selected is only selected on the problem of being confined to economic worth, many polymetallic ore mountains,
Low-grade metal is abandoned；The problem of in order to solve the low grade of ore in ore dressing and complicated ore composition, what the present invention was used
Method, with extremely low cost, the higher rate of recovery, the problem of ore dressing of low-grade polymetallic ore is solved well.Specific solution
Certainly scheme is as follows：
The content of the invention
The technical scheme that the beneficiation method that the present invention solves low-grade polymetallic ore is used is：A kind of low-grade many metals
The beneficiation method of ore deposit, this method is to complete ore dressing process using magnetic separator, automatic ore dressing chute, flotation device and shaking table.The party
Method ore dressing process is as follows：1st, automatic ore dressing chute roughing is used, rougher tailings flows automatically to next section of automatic ore dressing chute and scanned, scans
Mine tailing flows automatically to next section of automatic ore dressing chute and scanned again, so constantly repeats to scan and abandons mine tailing to no value, this
Stage obtains the first concentrate；2nd, the first obtained concentrate is transported to magnetic separator magnetic separation mineral containing magnetic, this stage obtains containing magnetic
Mineral concentrate；3rd, the Tailings transportation after magnetic separation scans recleaning Flotation of Sulfide Ores three times to flotation device one roughing, this
The individual stage has just obtained sulphide concentrate；4th, the mine tailing after flotation is then sent through another set automatic ore dressing chute and carries out essence
Choosing, is also repeatedly to be scanned by one roughing here, and cleaner tailings returns to raw ore to ore deposit, and this stage obtains the second concentrate；5、
It is further selected that second concentrate is sent to shaking table, and table concentrate is exactly final concentrate, and shaking table mine tailing returns to automatic ore dressing above
Chute is to ore deposit, and this completes whole ore dressing process.The beneficial effects of the invention are as follows：1st, abandoned using automatic ore dressing chute big
Partial mine tailing, only enters next process with the concentrate selected, because automatic ore dressing chute cost is extremely low, this reduces
Beneficiation cost, makes low-grade polymetallic ore have value；2nd, repeatedly scanned using automatic ore dressing chute, improve recovery
Rate.
