Problems solved by technology

Summarizing the mineral processing research results of Mine 801 over the past few decades, they all aim to obtain three products: rare earth concentrate, niobium concentrate and zirconium concentrate, but these three products all have the problems of low grade and low recovery rate, and the The amount of ore is large, accounting for 90% of the original ore. The radioactivity of the tailings exceeds the standard. The discharge of a large amount of radioactive tailings will cause potential environmental and safety hazards

Embodiment 1

[0034] With 5.00% total amount of rare metal zirconium, uranium, niobium, beryllium, rare earth and titanium minerals, Inner Mongolia 801 ore with 90% quartz feldspar content is used as raw material ore, and the following process steps are carried out by using the process method of the present invention:

[0035] (1) Strong magnetic separation: Take 1 kg of raw material ore with a particle size of -0.5mm accounting for 50%, and carry out a magnetic separation closed-circuit process of strong magnetic roughing and strong magnetic sweeping. The tailings are selected for strong magnetic scavenging, and the scavenging concentrate returns to the strong magnetic roughing process. The scavenging tailings are magnetic separation tailings. The magnetic field strength of the strong magnetic rough separation is 2.5T, and the magnetic field strength of the strong magnetic sweep is 1.6T;

[0036] (2) Magnetic separation concentrate re-election: Magnetic separation concentrate carries out o...

Embodiment 2

[0044] With the rare metal zirconium, uranium, niobium, beryllium, rare earth, titanium mineral total amount being 8.65%, Inner Mongolia 801 ore with a quartz feldspar content of 75.00% as a raw material ore, using the process method of the present invention, the following process steps are carried out:

[0045] (1) Strong magnetic separation: Take 1 kg of raw material ore with a particle size of -0.5mm accounting for 60.45%, and carry out a magnetic separation closed-circuit process of strong magnetic roughing and strong magnetic sweeping. The tailings are selected for strong magnetic scavenging, and the scavenging concentrate is returned to the strong magnetic roughing process. The scavenging tailings are magnetic separation tailings. 3.5T;

[0046] (2) Magnetic separation concentrate re-election: Magnetic separation concentrate is subjected to one stage of shaking table gravity separation, one stage of shaking table gravity separation obtains one stage of gravity separation...

Embodiment 3

[0054] With the rare metal zirconium, uranium, niobium, beryllium, rare earth, titanium mineral total amount of 10.25%, Inner Mongolia 801 ore with a quartz feldspar content of 82.67% is used as a raw material ore, and the process of the present invention is used to carry out the following process steps:

[0055] (1) Strong magnetic separation: Take 1 kg of raw material ore with a particle size of -0.5mm accounting for 55.63%, and carry out a magnetic separation closed-circuit process of strong magnetic roughing and strong magnetic sweeping. The tailings are subjected to strong magnetic scavenging, and the scavenging concentrate is returned to the strong magnetic roughing process. The scavenging tailings are magnetic separation tailings. 3.0T;

[0056] (2) Magnetic separation concentrate re-election: Magnetic separation concentrate is subjected to one stage of shaking table gravity separation, one stage of shaking table gravity separation obtains one stage of gravity separatio...

Abstract

The invention relates to a method for separating rare multi-metal concentrate and quartz feldspar concentrate. The method comprises the steps that strong magnetic separation is conducted on 801 ore, so that magnetic concentrate and magnetic tailing are obtained; table re-separation is conducted on the magnetic concentrate, so that re-separated magnetic concentrate and re-separated magnetic tailingare obtained, wherein the re-separated magnetic concentrate is multi-metal mixed concentrate containing uranium, niobium, beryllium, rare earth and titanium; table re-separation conducted on the magnetic tailing, so that re-separated nonmagnetic concentrate, re-separated nonmagnetic middling and re-separated nonmagnetic tailing are obtained, wherein the re-separated nonmagnetic concentrate is zirconium concentration, and the re-separated nonmagnetic middling is quartz feldspar concentrate. By adoption of the method for separating rare multi-metal concentrate and quartz feldspar concentrate, the resource utilization rate is remarkably increased, and the multi-metal mixed concentrate with the purity equal to or higher than 92% and the recovery rate equal to or higher than 70%, the zirconiumconcentrate with the zirconium grade equal to or higher than 60% and the recovery rate equal to or higher than 70%, and the quartz feldspar concentrate with the purity equal to or higher than 95% andthe recovery rate equal to or higher than 60% are obtained. In addition, the method adopts physical separation and thus is economical, environmentally friendly and efficient.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a method for separating rare polymetallic concentrates and quartz feldspar concentrates. Background technique [0002] The 801 mine has been famous for a long time and has attracted worldwide attention. It is rich in various rare metal resources such as zirconium, uranium, niobium, beryllium, rare earth, titanium, etc., among which the reserves of rare metal resources such as niobium, zirconium, beryllium, and rare earth are in the forefront of the country, and the reserves are huge. . 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. [0003] However, because the occurrence state of valuable elements in 801 ore is quite scattered, and the valuable elements in various minerals contain each ...
