[0002] The ores mined in China generally have the characteristics of being poor, fine and mixed, and the combined process of stage grinding, stage separation, gravity separation, magnetic separation and flotation is usually used for complex multi-metal ores containing rare earth, niobium and zircon, so that the separation process has many sub-items and a complex process, and the process involves the pre-concentration operation of rare earth and niobium flotation, concentrate concentration operation, gravity separation tailings and zircon concentrate concentration operation, so that more requirements are put forward for the concentration operation in the overall layout of the ore-dressing plant.
[0003] In the traditional overall layout of the ore-dressing plant, the concentration operation is usually arranged around the main mill building according to the terrain, but when different concentration operations of multiple minerals are required in the process flow, the traditional concentration operation arrangement will make the plant room pipeline arrangement more complex, increase the slurry pipeline conveying capacity and increase the capital investment.
[0004] In view of this, the utility model is provided. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims to provide a rare earth, niobium and zircon multi-metal ore-dressing plant configuration system, which has higher adaptability to the complex multi-metal ore process and can save capital investment and facilitate production and operation.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0007] A rare earth, niobium and zircon multi-metal ore-dressing plant configuration system, comprising a first plant area, a second plant area, a third plant area, a fourth plant area and a fifth plant area, wherein the first plant area, the second plant area, the third plant area, the fourth plant area and the fifth plant area are arranged in sequence along the longitudinal direction;
[0008] The first plant area comprises a coarse crushing workshop, a medium and fine crushing workshop and a screening workshop;
