Abstract

The invention discloses a separation and purification method for garnets of iron ore tailings. The method includes the following steps that firstly, the iron ore tailings are led into a flat plate strong magnetic separator to be subjected to tailings discharging separation under the magnetic field strength being 1300 mt-1500 mt, and magnetic minerals and non-magnetic minerals are obtained; secondly, the magnetic minerals are led into a cylindrical strong magnetic separator, and the strong magnetic minerals and the weak magnetic minerals are separated under the magnetic field strength being 350 mt-400 mt; thirdly, the weak magnetic minerals are subjected to screening and classifying operation, the classified weak magnetic minerals are sorted through jigging and a shaking table according to the particle granularity, and garnet particles and silicate minerals which are large in density difference are separated out; and fourthly, the garnet particles are subjected to dry type strong magnetic separation, garnet concentrates and weak magnetic minerals with the magnetization coefficient smaller than that of the garnet concentrates are separated out, and the garnet concentrates are obtained. The invention further discloses the garnet concentrates. By means of the separation and purification method for the garnets of the iron ore tailings, no auxiliary needs to be added, the separation and purification difficulty is lowered, and the purity of the prepared garnets is improved.

Description

technical field [0001] The invention relates to a beneficiation process, in particular to a method for separating and purifying iron ore tailings garnet and its products. Background technique [0002] At present, the country attaches great importance to the comprehensive utilization of tailings. Due to the limitations of human understanding, scientific and technological level and various related factors, it is still impossible to recycle all the useful components in tailings in the production process. Therefore, in the tailings The ore also contains certain useful ingredients to varying degrees. With the continuous improvement of human understanding and the development of science and technology, the problem of comprehensive recovery and utilization of tailings has emerged, and repurification of useful minerals and components from tailings is the most important method of tailings recycling. way of using. [0003] In the iron ore tailings of a Tiangao Mining Company, the mai...
