The impact of the production of ammonium metatungstate on the environment is mainly reflected in the following aspects:
Raw material extraction and processing
In the extraction process of tungsten ore, strong acids such as hydrofluoric acid or sulfuric acid are used to extract tungsten elements from tungsten ore to form a tungsten slurry suspension. This step may produce wastewater containing heavy metals and harmful chemicals, which may pollute the environment if not properly treated.
In the tungsten nitrate precipitation process, excess nitric acid is added to make tungsten element undergo redox reaction to form tungsten oxide and precipitate tungsten nitrate. This process may also generate wastewater and exhaust gas, which need to be disposed of properly.
Ammonia addition and hydrolysis reaction
Tungsten nitrate is hydrolyzed in ammonia to form ammonia and metatungstic acid. In this process, the use of ammonia and the hydrolysis reaction may generate ammonia and other harmful gases, which need to be strictly controlled to avoid air pollution.
Wastewater treatment
Wastewater generated in the production process of ammonium metatungstate may contain pollutants such as heavy metals, harmful chemicals and ammonia nitrogen. If the wastewater is discharged directly without effective treatment, it will pollute the water body and affect the survival of aquatic organisms and ecological balance.
Exhaust gas treatment
Exhaust gases from the production process may contain harmful gases such as ammonia and sulfur dioxide. These exhaust gases need to be properly treated, such as absorption, adsorption, catalytic conversion, etc., in order to reduce the pollution to the atmosphere.
Solid Waste Treatment
Solid wastes generated during the production process, such as waste slag and spent catalysts, need to be properly treated and disposed of to avoid pollution of soil and groundwater.
Energy consumption and carbon emission
The production process of ammonium metatungstate needs to consume a large amount of energy, such as electricity and steam. These energy consumptions not only increase the production cost, but also increase the carbon emission, which has a certain impact on the environment.
In order to reduce the impact of ammonium metatungstate production on the environment, the following measures can be taken:
Strengthen the treatment and management of wastewater, waste gas and solid waste to ensure that they are discharged according to standards.
Adopt clean production process and equipment to reduce energy consumption and carbon emission.
Strengthen environmental monitoring and assessment to detect and deal with environmental problems in a timely manner.
Strengthen the training of employees’ environmental protection awareness to improve environmental awareness and responsibility.
To sum up, the production of ammonium metatungstate has a certain impact on the environment, but by adopting appropriate measures and management methods, its adverse impact on the environment can be minimized.
