Embodiment 1

[0025] Mix copper sulfate and deionized water at a ratio of 3:8.2, and then shake rapidly in a shaker for 9 minutes to obtain a primary solution. Potassium molybdate and deionized water were mixed according to the ratio of 2:9, and then oscillated rapidly in a shaker for 9 minutes to obtain a secondary solution. The primary solution and the secondary solution were mixed at a ratio of 1:1, and then shaken rapidly in a shaker for 3 hours to obtain a mixed solution. The mixed solution was aged at room temperature for 16 hours, the aged solution was filtered, washed 3 times with deionized water, and then dried for a period of time at a drying temperature of 90°C and a drying time of 4 hours to obtain a primary solid Product: Put the primary solid product into a roasting furnace for roasting at a roasting temperature of 500° C. and a roasting time of 3.5 hours to obtain a copper molybdate adsorption material. The copper molybdate adsorption material, CuO content is 61 ~ 64wt%, MoO...

Abstract

The invention relates to a copper molybdate adsorbing material. The content of CuO is 61-64wt%, the content of MoO3 is 22-25wst%, and the average particle diameter of copper molybdate particles is 300-350nm. A preparation method comprises the following steps: mixing copper sulfate and deionized water, and then quickly vibrating the mixture for a period of time in a vibrator to obtain a primary solution; mixing potassium molybdate and the deionized water, and then quickly vibrating the mixture for a period of time in the vibrator to obtain a secondary solution; mixing the primary solution and the secondary solution, and then quickly vibrating the mixture for a period of time in the vibrator to obtain a mixed solution; aging, filtering and washing the mixed solution, and then performing drying for a period of time to obtain a primary solid product; and roasting the primary solid product in a roasting furnace to obtain the copper molybdate adsorbing material. The copper molybdate adsorbing material provided by the invention has small copper molybdate impurity content, high purity and good particle size uniformity and has good adsorption capacity to xanthate.

Description

technical field [0001] The invention relates to the environmental protection field of mineral processing wastewater treatment, in particular to a copper molybdate adsorption material and a preparation method thereof. Background technique [0002] Since my country's reform and opening up, with the introduction of foreign technology and the maturation of the domestic market environment, in the past 30 years, the industry has developed rapidly. The rapid development of industry has promoted economic take-off, but it cannot be ignored that for a long time, the heavy industrialization of my country's industrial structure has led to high consumption of resources and energy, and high pollution to the environment. The hazards of air pollution and industrial wastewater have seriously affected people's health. Pollution has become the biggest livelihood issue, and it is imperative to adjust the industrial structure and strictly reduce energy conservation and emission reduction. [0...
