Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to the magnetic tailing that carbonic acid iron content is more than 3% is sorted
A kind of pre-selection-roasting-magnetic heavy industry skill recycling magnetic tailing method.
Background technology
The method recycled at present to magnetic tailing of the valuable mineral based on Armco magnetic iron mineral, it is common that using magnetic
Choosing-dusting cover-magnetic separation process or single magnetic separation process are sorted, and the Armco magnetic iron mineral in magnetic tailing are returned so as to reach
It receives, obtains the purpose of qualified iron ore concentrate.The selection of single magnetic separation process or magnetic separation-dusting cover-magnetic separation process is according to magnetic tailing
The size of middle Armco magnetic iron mineral disseminated grain size and it is determining, be specifically summarized as follows：
Magnetic separation-dusting cover-magnetic separation process：
For Armco magnetic iron mineral disseminated grain size in magnetic tailing more than 30 particles, regrind granularity -0.074mm contents 95% with
Under magnetic tailing, magnetic separation-dusting cover-magnetic separation process generally can be used, it is common that throwing tail is carried out using disc type recycling machine first, so
It after being regrinded afterwards to recycling machine concentrate, then carries out weak magnetic machine and sorts, weak magnetic machine concentrate feeds dusting cover, and dusting cover undersize passes through again
Become final concentrate after weak magnetic machine is selected, it is weak that the return of dusting cover oversize feeds weak magnetic machine-dusting cover-again after regrinding or individually regrinding
Magnetomechanical is sorted, and is formed closed circuit；
Single magnetic separation process：
For Armco magnetic iron mineral disseminated grain size in magnetic tailing in 30 particles hereinafter, regrind granularity -0.046mm contents 90% with
On magnetic tailing, single magnetic separation process generally can be used, it is common that throwing tail is carried out using disc type recycling machine first, then to return
After receipts machine concentrate is regrinded, then combined using multistage magnetic separator or dehydration slot and magnetic separator and sort acquisition concentrate.
For iron mineral disseminated grain size at 0 ~ 30 micron, regrind particulate magnetic of the granularity in more than 90% -0.046mm contents
Iron ore mine, the major defect sorted using single magnetic separation process or magnetic separation-dusting cover-magnetic separation process are：
1）Magnetic concentration working regrind granularity it is meticulous when be easy to cause magnetism and be mingled with, high-grade concentrate can not be obtained；2）Regrind granularity
It is meticulous, mutually in requisition for thinner dusting cover screen size, sieve pore blockade is easily caused in production；Otherwise, need relatively low dusting cover to
Ore deposit concentration and larger flushing water, are not easy to realize in production.
The method that the synthesis tailing of the bloodstone to valuable mineral based on weak magnetism mineral is recycled at present, recycling
Rate it is higher be pre-selection-calcining magnetic separation process, pre-selection technique is generally using magnetic separation-regrind-magnetic separation process, and specific summary is such as
Under：
The high intensity magnetic mineral that comprehensive tailing obtains after one section of high-intensity magnetic separation feeds grinding classification system, and ore milling product is strong through two sections again
Magnetic separation is other, and the last two essence is concentrated, carries out reduction roasting after filtering, and product is sorted through weak magnetic after roasting, and inferior fine magnetite concentrate is again through ore grinding
Afterwards, then using weak magnetic selected, acquisition final concentrate is carried out.
Carbonic acid iron content is higher in the magnetic iron ore of part valuable mineral fine-grained disseminated grain at present, reaches more than 3%.Magneticore-dressing plant adopts
Such magnetic iron ore is handled with the single magnetic separation technological process of production, ferric carbonate substantially enters magnetic tailing.To such magnetic tailing
Recovery process and method, particularly to the recovery process of ferric carbonate and method carry out further investigation inquire into have realistic meaning.
The recovery process of the existing above-mentioned magnetic tailing to valuable mineral based on Armco magnetic iron mineral is used, it is not only magnetic
Iron recovery is relatively low, and can not recycle the ferric carbonate being lost in tailing completely；
The recovery process of the synthesis tailing of the existing above-mentioned bloodstone to valuable mineral based on weak magnetism mineral is used,
Pre-selection technique is magnetic separation-regrind-magnetic separation, recycles the ferric carbonate in magnetic tailing using strong magnetic, regrinds front and rear two sections of high intensity magnetic minerals
Grade compared with to ore deposit, a strong concentrate concentrate 15% hereinafter, two strong concentrate concentrates 21% hereinafter, increase rate is minimum, as a result pay no attention to
Think；Then it is reasonable using roasting technique, ferric carbonate can be converted into Armco magnetic iron, but follow-up low intensity magnetic separation operation will obtain grade
65% iron ore concentrate, -500 more than 97% mesh will be reached by regrinding granularity, regrind that granularity requirements are too thin, and cost is high, and are difficult to realize
Commercial Application.
