Abstract

The invention relates to a basic cupric carbonate adsorption material. The basic cupric carbonate adsorption material comprises 45 to 49 weight percent of CuO and 24 to 35 weight percent of C, whereinthe average particle size of basic cupric carbonate particles is 60 to 110 nm. A preparation method comprises the following steps: mixing copper sulphate and deionized water to prepare a primary solution, and heating for a period of time; mixing potassium carbonate and deionized water to prepare a secondary solution, and heating the secondary solution in a water-bath device; adding the primary solution into the secondary solution, and stirring; adding sodium hydroxide to regulate a pH value, then continuing stirring for a period of time, and then cooling; aging the cooled solution, then filtering and washing; drying the washed product to obtain the basic cupric carbonate adsorption material. The basic cupric carbonate provided by the invention is low in impurity content, high in purity and high in particle size uniformity, and has very 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 basic copper carbonate 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....
