Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to a kind of radioactive beneficiation method of quartzy feldspar concentrate of removal.
Background technique
China march toward medium-developed country road on, it is also necessary to the support of long-term a large amount of resource.With mineral resources
It is increasingly deficient, it is low-grade, associated resources have been put into the main force's resource to be large-scale developed and utilized altogether, especially rare, rare earth,
Dilute scattered equal strategic resources.However this strategic resource is in the process of development, since head grade is low, can generate a large amount of tailing,
Wherein having quite a few is the enriched substance of quartzy feldspar, but " three is dilute " resource often contains higher radioactivity simultaneously, causes
This quartz feldspar can not be utilized because radioactivity is exceeded, in addition, also can the similar quartz length of output in the wet metallurgy course of uranium
The long-term bulk deposition of stone enriched substance, this exceeded tailing of radioactivity causes long-term hidden danger to area surroundings.
Many for quartzy feldspar method of purification at present, the method for quartzy feldspar Mineral separation is also very mature but few
Radioactive method or correlative study are removed to quartzy feldspar bulk concentrate, water washing is simply used, acid elution, magnetic separation, floats
The methods of choosing all cannot effectively be removed containing radioactivity.
The present invention uses the united technique of preparing of magnetic separation-gravity treatment, can not only effectively reduce quartzy feldspar bulk concentrate
In radioactivity, and this method is not necessarily to any chemical reagents, existing economic effect using a kind of ore dressing mode of pure physics
Benefit has environmental benefit again.
Summary of the invention
Based on problem above, one purpose of the invention is to provide a kind of beneficiation method, can remove high radioactivity quartz
The high radioactivity of feldspar concentrate.
The technical solution of the present invention is as follows:
The present invention provides a kind of quartzy feldspar concentrate of removal radioactive beneficiation method, comprising the following steps:
(1) high intensity magnetic separation: carrying out ore grinding for the exceeded quartzy feldspar bulk concentrate of radioactivity, then by the fine powder after ore grinding into
Row high intensity magnetic separation, the high intensity magnetic separation include one roughing and once purging selection composition closed circuit flow, obtained after roughing rougher concentration and
The rougher tailings is carried out once purging selection, obtains scavenger concentrate and scan tailing, the scavenger concentrate is passed through by rougher tailings
Closed circuit flow returns to one roughing, and the tailing of scanning is strong magnetic tail mine；
(2) one sections of table concentrations: carrying out one section of table concentration for the strong magnetic tail mine, obtain one section of table concentration concentrate and
One section of table concentration tailing；
(3) two sections of table concentrations: carrying out ore grinding for one section of table concentration tailing, then carry out two sections of table concentrations,
Obtain two sections of table concentration concentrate, two sections of table concentration chats and two sections of table concentration tailings, two sections of table concentration chats
As remove radioactive quartzy feldspar concentrate.
