Standard of Zinc Concentrate Quality
Zinc concentrate is the coarse powder consisted of zinc and lead zinc ore. As an important product of first grade ore extraction, it is widely used in metallurgical industry and chemical engineering industry. Zinc concentrate has wide adaptability and is suitable for many purposes. In order to meet the different requirements of the industry and obtain good economic benefits, the quality of zinc concentrate must meet certain standards.
The general standard for zinc concentrate quality is that the content of zinc should exceed 50%, the content of lead can not exceed 10%, and the content of certain impurities should be limited. The main requirements of the quality of different kinds of zinc concentrate are as follows:
1. Zinc concentrate production standard: Zinc concentrate production should meet the occupational health, safety and environmental protection requirements, and take effective dust, toxic gas, noise and wastewater treatment measures. It is also required that the size of zinc concentrate particles should fall within the requirement range and the content of harmful impurities should not exceed the national standard.
2. Zinc concentrate product quality standard: It is required that the content of zinc in zinc concentrate should be higher than 50%, the content of lead should not be higher than 6%, and the content of harmful impurities should not exceed the national standard.
3. Zinc concentrate deep processing standard: Zinc concentrate deep processing products should meet the requirements of aluminum and powder catalyst in the chemical industry, and the purity of zinc powder and zinc oxide should be higher than 99.6%.
The above are the standards of zinc concentrate quality in general. In addition, according to the needs of specific users, the content of certain impurities in zinc concentrate may be further limited.
In summary, zinc concentrate quality should meet the requirements of occupational health, safety, environmental protection and product quality. Only by ensuring the quality of zinc concentrate according to the industry standards, can we effectively guarantee the product quality in the processing and use of zinc concentrate and obtain the maximum economic benefits.
