Problems solved by technology
[0004] The parameters of the traditional paste filling dense dehydration process are mostly determined on the basis of experience, and a certain margin coefficient is reserved. Some of the results of laboratory testing have low precision and large errors, resulting in unreasonable selection of tailings slurry thick dehydration process and unreasonable technical parameters. Accurate, large investment, poor operation effect

Abstract
The invention relates to a gold mine tailings slurry automatic suction filtration dehydration performance testing system and method, belonging to the field of gold mine tailings paste filling. The system includes a central automatic control system, a feeding system, a flocculant preparation and supply system, a water supply system, a double-disk suction filtration system, and a filter cake moisture content measurement system. The whole tailings slurry of the dressing plant is pumped into the hopper of the feeding system, and the quantitative full tailings slurry is automatically controlled to the double-disk suction filtration system, and the dilution water and pressure regulating water are automatically supplied according to the system pressure and slurry concentration requirements, and prepared and supplied Flocculant, when there is no upper layer of water on the surface of the filter cake in the plate, the central automatic control system will automatically output the test report. The invention can realize the automatic suction filtration and dehydration performance test of tailings slurry with different physical and chemical properties in gold mines, has high test accuracy, avoids cumbersome operations such as manual batching and manual control errors, and is convenient and simple to operate, ensuring the specific mine tailings dehydration process design It is supported by accurate test data, and also provides an efficient and convenient sample dehydration method for laboratory tests.
Description
technical field [0001] The patent of the invention belongs to the field of gold mine tailings paste filling, and specifically relates to a gold mine tailings slurry automatic suction filtration dehydration performance test system and a test method. Background technique [0002] Green and environmental protection is the general trend of mining development, and filling mining, especially paste filling, has gradually become an important part of the green development of mining enterprises. The tailings dehydration process of the dressing plant is an important link in the preparation of mine tailings paste filling materials, and the quality of dehydration directly affects the filling quality. [0003] The dehydration of tailings slurry in the concentrator is an important link in the preparation of mine tailings paste filling materials. The dehydration performance is different for tailings with different physical and chemical properties. At present, mines mainly use vertical sand...
