Embodiment 1

[0024] Mix 1-propanol and deionized water at a ratio of 4:1 to prepare a primary solvent; mix copper chloride and potassium hydroxide at a ratio of 2:1.5, then add the primary solvent, then stir for 20 minutes, and then Shake at a low speed for 30 minutes in a shaker to obtain a primary solution. Sodium tungstate was mixed with the primary solvent at a ratio of 2:1, and then added to the primary solution, then stirred for 35 minutes, and then oscillated in a shaker at high speed for 40 minutes to obtain a secondary solution. Put the secondary solution into an autoclave, place the autoclave in an oven to react for a period of time, the temperature in the oven is 100°C, and the reaction time is 24h, then cool naturally, and filter to obtain the primary solid product. The primary solid product was washed three times with deionized water, and then dried for a period of time at a drying temperature of 60° C. and a drying time of 6 hours to obtain a basic copper tungstate adsorption...

[0026] Mix 1-propanol and deionized water at a ratio of 4.5:1.5 to prepare a primary solvent; mix copper chloride and potassium hydroxide at a ratio of 2.5:1.8, then add the primary solvent, then stir for 25 minutes, and then Shake at a low speed for 35 minutes in a shaker to obtain a primary solution. Sodium tungstate was mixed with the primary solvent at a ratio of 2:1, then added to the primary solution, then stirred for 40 minutes, and then oscillated at high speed in an oscillator for 45 minutes to obtain a secondary solution. The secondary solution was put into an autoclave, and the autoclave was placed in an oven to react for a period of time. The temperature in the oven was 110° C., and the reaction time was 25 hours. Then, it was naturally cooled and filtered to obtain the primary solid product. The primary solid product was washed 4 times with deionized water, and then dried for a period of time at a drying temperature of 65° C. and a drying time of 6.5 hours to obta...

Embodiment 3

[0028] Mix 1-propanol and deionized water in a ratio of 5:2 to make a primary solvent; mix cupric chloride and potassium hydroxide in a ratio of 3:2, add the primary solvent, stir for 30 minutes, and then Shake at a low speed for 40 minutes in a shaker to obtain a primary solution. Sodium tungstate was mixed with the primary solvent at a ratio of 2:1, then added to the primary solution, then stirred for 45 minutes, and then oscillated in a shaker at high speed for 50 minutes to obtain a secondary solution. The secondary solution was put into an autoclave, and the autoclave was placed in an oven to react for a period of time. The temperature in the oven was 120° C., and the reaction time was 26 hours. Then, it was naturally cooled and filtered to obtain the primary solid product. The primary solid product was washed 5 times with deionized water, and then dried for a period of time at a drying temperature of 70° C. and a drying time of 7 hours to obtain a basic copper tungstate ...

Abstract

The invention relates to an alkali copper tungstate adsorption material which comprises 25-30wt% of CuO and 10-19wt% of WO2, and the average particle size of alkali copper tungstate granules is 6-10 nm. A preparation method comprises the following steps: mixing 1-propyl alcohol and deionized water to prepare a primary solvent; mixing copper chloride and potassium hydroxide, further adding the primary solvent, stirring for a certain time, and performing low-speed oscillation in an oscillator for a certain time so as to obtain a primary solution; mixing sodium tungstate with the primary solvent,further putting into the primary solution, stirring for a certain time, and further performing high-speed oscillation in the oscillator for a certain time so as to obtain a secondary solution; putting the secondary solution into a high-pressure kettle, putting the high-pressure kettle into a baking oven, performing a reaction, naturally cooling, and filtering so as to obtain a primary solid product; and washing the primary solid product with deionized water, and drying, thereby obtaining the alkali copper tungstate adsorption material. The alkali copper tungstate adsorption material is low incopper tungstate impurity content, high in purity, high in particle size uniformity and good in xanthate adoption.

Description

technical field [0001] The invention relates to the environmental protection field of ore dressing wastewater treatment, in particular to a basic 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...
