Excessive impurity content in tungsten ore will bring a series of hazards, which can be expressed and summarized from multiple perspectives:
Hazards to the environment and ecology
During the mining and processing of tungsten ore, if the impurity content is too high, it will increase the emission of wastewater, waste gas and solid waste. These emissions contain a large amount of heavy metals, organic matter and other harmful substances. Direct discharge will pollute surface water and groundwater, endangering the ecosystem and human health.
Especially in areas near tungsten mines, water sources are seriously polluted, which may cause damage to the ecosystem, affect the growth of crops and the safety of drinking water for humans and livestock.
Hazards to human health
Workers who produce tungsten ore may develop occupational diseases such as pneumoconiosis if they are exposed to dust containing impurities for a long time. For example, tungsten ore dust has a strong fibrosis ability, and long-term inhalation may cause pneumoconiosis. Even if appropriate personal protection measures are taken, it may develop after several months to years.
Some elements in impurities, such as sulfur, phosphorus, arsenic, etc., may have toxic effects on the human body. Long-term excessive exposure to compounds of these elements may cause health problems such as respiratory diseases and gastrointestinal disorders.
Impact on product quality
Excessive impurity content in tungsten ore will affect the purity and quality of the final product. During the extraction and precipitation of tungsten, impurities may form stable compounds with tungsten, resulting in precipitation failure or reduced product purity.
Low-purity tungsten products may not meet the high requirements for material properties in specific industries (such as aerospace, electronics, etc.), affecting the performance and life of the product.
Impact on economic benefits
Excessive impurity content will increase the mining and processing costs of tungsten ore. In order to remove or reduce the impurity content, more complex physical and chemical beneficiation methods, as well as more advanced equipment and technology may be required.
At the same time, low-purity tungsten products may be difficult to sell or have a low price, affecting the economic benefits and market competitiveness of the enterprise.
Excessive impurity content in tungsten ore will not only cause damage to the environment and ecology, but also have a negative impact on human health, product quality and economic benefits. Therefore, in the mining and processing of tungsten ore, effective measures need to be taken to remove or reduce the impurity content to ensure that the purity and quality of the product meet relevant standards and requirements.
