Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] The raw ore first enters the 1st desliming screen, and the deslimed ore mixture enters the 2nd three-product dense medium cyclone. Add the dense medium suspension with the optimal concentration determined experimentally into the 2-three-product dense medium cyclone.

[0024] 2 The three-product dense medium cyclone is the most important part of the separation system. It consists of a cylinder and a cone. When rotating, the vortex separates. Taking advantage of the similar density of calcite and dense medium suspension, the calcite is first separated in the cylinder seperate. The rest of the ore enters the second section of the cone and continues to rotate. Due to the different specific gravity and centrifugal force of barite and fluorite during rotation, it is finally separated through different outlets.

[0025] The separated ore products enter different 3-...

Abstract

The invention discloses a dense medium beneficiation method for barites. According to the dense medium beneficiation method, dense medium suspension liquid with proper density is prepared according todifferent densities of minerals and is utilized for separating usable minerals and gangue minerals, and two minerals with the density difference equal to or more than 0.2g / cm<3> can be effectively separated. The dense medium beneficiation method has the beneficial effects that low-grade resources can be processed, and the total reserves of the minerals can be increased; and universal and standardauxiliary equipment is adopted in the whole separation process, is low in investment, small in occupied area, easy to operate, low in operation cost and applicable to complete automatic control, so that the economic benefit of mines can be greatly increased.

Description

technical field [0001] The invention belongs to the field of mineral resource development, and in particular relates to a dense-medium beneficiation method for barite. Background technique [0002] China's barite resources are very rich, mostly associated with other minerals, and have the characteristics of difficult mineral processing. At present, most barite separation methods are hand selection, peptide skipping, flotation and other methods with low production efficiency and large waste of resources. With the increase in the basic investment and operating costs of sorting, as well as the concern for environmental issues, the barite sorting process needs to be optimized and improved urgently. [0003] Among the existing barite minerals, fluorite, calcite and other ores are most often associated with barite minerals. The specific gravity of barite is 4.3-4.5g / cm 3 , the specific gravity of fluorite is 3.0-3.3g / cm 3 , the specific gravity of calcite is 2.75g / cm 3 . Co...
