Background technology
Discarded object of the tailings sand stone ore after beneficiation flowsheet, wherein containing the valuable mineral not reclaimed completely largely,
In practice, these general tailing wastes destroy natural, ecological and easily trigger the danger such as mud-rock flow in tail dam ore deposit.The inside has
The wasting of resources is also resulted in mineral.
The content of the invention
It is an object of the invention to provide a kind of disk feeder, to solve the problems mentioned in the above background technology.
The technical problems to be solved by the invention are realized using following technical scheme：
It is a kind of that Iron concentrate, the method for magnetic iron ore are extracted from tailings, comprise the following steps：
Step one：Tailings is sieved for the first time, the stone of the inside or the tailings of large volume is screened out, makes tailings particle size
Control is in below 20mm；
Step 2：Tailings continuously is sent into cutting machine by continuous feeder and pipeline to be crushed, just ore deposit is formed；
Step 3：Cutting machine and grader are arranged to closed-circuit system, first ore deposit is classified, thin ore deposit is obtained；
Step 4：Thin ore deposit is added water, collecting agent, activator, suppression agent and blowing agent ore pulp is made, into flotation device, flotation
During it is selected after obtain Iron concentrate, be discharged into Sha Chi, mine tailing obtained after scanning；
Step 5: the mine tailing produced in previous step enters magnetic separator magnetic separation, the magnetic iron ore magneticly elected is dehydrated, and makes it
