Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to a kind of to sort rare Complex concentrate and quartzy feldspar concentrate
Method.
Background technique
801 mines are well-known for a long time, attract worldwide attention, rich in a variety of rare metal resources such as zirconium, uranium, niobium, beryllium, rare earth, titaniums, wherein
The reserves of the rare metal resources such as niobium, zirconium, beryllium, rare earth occupy domestic forefront, and reserves are huge.According to statistics, the zirconium reserves of 801 mines
About 371.88 ten thousand tons, about 30.93 ten thousand tons of niobium reserves, about 6.4 ten thousand tons of beryllium reserves, about 78.44 ten thousand tons of rare earth reserves.
However, the valuable element in various mineral mutually contains sternly since the occurrence status of valuable element in 801 mines quite disperses
Weight, causes ore dressing to be unable to get single, high-grade rare metal concentrate, and thorium, the uranium content in 801 mines are high, belong to and put
Penetrating property mine.So far from 1970s discovery, it is studied through more than 40 years, is not able to achieve the development and utilization of 801 mines yet.Summarize 801
The beneficiation research achievement of mine in decades, be all to obtain three kinds of rare earth ore concentrate, niobium concentrate and zircon concentrate products as target, but this
Three kinds of products all have that grade is low, the rate of recovery is low, and tailing amount is big, account for the 90% of raw ore, and the radioactivity of tailing is super
Mark, the discharge of a large amount of radioactivity tailings will cause potential environment and security risk.In fact, most important mine in the tailing
Object is that quartz and feldspar, total content reach the 90% of tailing amount, if realizing the recycling of quartz and feldspar in tailing, tailing
Discharge amount will greatly reduce.
So realizing that the yttriums such as 801 mine uranium, niobium, zirconium, beryllium, rare earth, titanium recycle entirely, and realize stone in tailing
The recycling of English, feldspar, it is that the faced key core of 801 mines development and utilization is asked only that 801 mine valuable resources, which are eaten dry squeeze,
Topic.
Summary of the invention
In order to solve the above problems existing in the present technology, the present invention provides a kind of rare Complex concentrates of sorting, zirconium
The method of concentrate and quartzy feldspar concentrate.It can be simultaneously from rare more metal raw ores (801 mine of the Inner Mongol) using the method for the present invention
