Abstract

The invention relates to a copper tungstate material for adsorption. The content of CuO is 52-61 wt%, the content of WO2 is 25-30 wt%, and the average particle size of copper tungstate particles is 0.4-0.6 mum. The method includes mixing copper sulfate with deionized water and performing ultrasonic treatment for a certain period of time to obtain a primary solution; mixing sodium tungstate and deionized water and performing ultrasonic treatment for a certain period of time to obtain a secondary solution; mixing the primary solution and the secondary solution, and performing ultrasonic treatment for a certain period of time to obtain a mixture solution; ageing the mixture solution; filtering the aged mixture solution, washing an obtained product, and drying the product for a certain periodof time to obtain a primary solid product; and calcinating the primary solid product in a calcinatory to obtain the copper tungstate material for adsorption. The copper tungstate material for adsorption is low in impurity contents, high in purity, good in particle size uniformity, and has good xanthate absorbing capability.

Description

technical field [0001] The invention relates to the environmental protection field of mineral processing wastewater treatment, in particular to a copper tungstate 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...
