Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to a kind of sorting rare metal concentrate, zircon concentrate and quartzy feldspar
The beneficiation method of concentrate.
Background technique
801 mine of Inner Mongolia Autonomous Region Tongliao is rich in the more of a variety of rare metal resources such as zirconium, rare earth, uranium, niobium, beryllium, titanium
Metallic ore, stock number estimate 2.4 hundred million tons, and reserves are huge, wherein the reserves of a variety of rare metal resources such as niobium, zirconium, beryllium, rare earth
Domestic forefront is occupy, according to statistics, about 371.88 ten thousand tons of the zirconium reserves of 801 mines, about 30.93 ten thousand tons of niobium reserves, beryllium reserves are about
6.40 ten thousand tons, about 78.44 ten thousand tons of rare earth reserves, but the yttriums content such as rare earth, uranium, niobium, beryllium, titanium in 801 mines
It is lower, and the occurrence status of yttrium quite disperses, and the valuable element in various mineral mutually contains seriously, leads to ore dressing
Expect that single, high-grade rare metal concentrate difficulty is larger, even if having obtained single rare earth ore concentrate, niobium concentrate, zirconium essence
Mine and ferro-niobium concentrate, but its concentrate the problems such as that there are still grades is low, the rate of recovery is low, radioactive element dispersion, and each concentrate does not have
There is the wet-process metallurgy craft of economic environmental protection；Secondly tailing amount is big and radioactivity is exceeded, and mineral processing circuit is complicated, and beneficiation cost is higher,
Be related to simultaneously gravity treatment, magnetic separation, flotation etc. it is more in ore dressing means, radioactivity tailing and the flotation waste water pressure caused by environment compared with
Greatly, above the reason is that 801 mines is caused to be not carried out the key factor that comprehensive utilization is developed over more than 40 years.
If pressing mineral all in 801 mines than reclassification, it can be found that the specific gravity of most yttriums is all big
In gangue mineral, and in gangue mineral, 85% the above are quartz and feldspars, therefore, if being started with gravity treatment, in conjunction with magnetic separation process,
Design of beneficiation process is carried out to 801 mines, it can be by most yttrium efficiently concentratings, then to the stone in gangue mineral
English and feldspar are recycled, then the classification of all valuable element economical rationality in 801 mines may be implemented, in conjunction with it is existing or
The advanced environmentally friendly wet-process metallurgy craft ground, then may be implemented the comprehensive development and utilization of 801 mines.
