Based on the permeability characteristics of tailings paste storage and industrial application scenarios, this paper takes a nickel tailings as the experimental object and uses variable water head penetration experiment to measure the permeability rate of tailings paste with concentrations of 66%, 68% and 70% respectively, and the dosage of flocculant is 15g/t, 20g/t, 25g/t, 30g/t, 35g/t and 40g/t. The research results show that the order of permeability rate of tailings paste with different concentrations is 15g/t < 25g/t < 20g/t < 30g/t < 35g/t < 40g/t, which indicates that the amount of flocculant can improve the permeability characteristics of tailings paste, and provides a theoretical basis for the development of paste storage technology in rainy areas.
