[0002] Tongliao 801 Mine in Inner Mongolia Autonomous Region is a polymetallic mine rich in zirconium, rare earth, uranium, niobium, beryllium, titanium and other rare metal resources. The reserves of a variety of rare metal resources are in the forefront of the country. According to statistics, the 801 mine has about 3.7188 million tons of zirconium reserves, about 309,300 tons of niobium reserves, about 64,000 tons of beryllium reserves, and about 784,400 tons of rare earth reserves. The content of rare metal elements such as rare earth, uranium, niobium, beryllium, titanium, etc. is low, and the occurrence state of rare metal elements is quite scattered, and the valuable elements in various minerals contain each other seriously, which leads to a single, high-grade rare metal in mineral processing. Metal concentrates are more difficult. Even if a single rare earth concentrate, niobium concentrate, zirconium concentrate, and ferroniobium concentrate are obtained, the concentrates still have problems such as low grade, low recovery rate, and scattered radioactive elements. There is no economical and environmentally friendly water smelting process for concentrates; secondly, the amount of tailings is large and the radioactivity exceeds the standard, the beneficiation process is complicated, and the beneficiation cost is high. The flotation wastewater puts a lot of pressure on the environment. The above reasons are the key factors that have led to the failure of the 801 mine to realize comprehensive utilization and development for more than 40 years.

Abstract

The invention relates to a beneficiation method for sorting rare metal concentrate, zirconium concentrate and quartz feldspar concentrate. The beneficiation method comprises the following steps of: reselecting 801 ores through a multistage shaking table to obtain concentrate, and performing closed-loop strong magnetic separation on the concentrate obtained by reselecting to obtain rare multi-metalmixed concentrate which is rich in rare earth, uranium, niobium, beryllium and titanium, wherein purity of valuable minerals in the rare multi-metal mixed concentrate is higher than or equal to 92%,and a recovery rate is higher than or equal to 70%, and zirconium concentrate with a zirconium grade higher than or equal to 60% and a recovery rate higher than or equal to 70% further can be obtained; performing open-circuit strong magnetic separation on middling obtained by reselecting to obtain quartz feldspar concentrate with quartz feldspar mineral purity higher than or equal to 95% and a recovery rate higher than or equal to 60%, combining secondary concentrate reselected through the multistage shaking table and tailings, and performing concentration, desliming and shaking table reselecting to increase the recovery rate of concentrate. According to the method disclosed by the invention, no chemical reagent is added in a beneficiation process which belongs to a physical beneficiationprocess, and therefore, the method is an economical, environmentally-friendly and efficient beneficiation method.
