High-grade pyrite typically requires a sulfur content of over 48%, and not every mine produces lumpy high-grade pyrite-it must be formed through hydrothermal enrichment during ore genesis.
Since the raw ore contains gangue, it first undergoes water washing to remove impurities and manual selection of gangue, thereby increasing sulfur content and reducing impurity levels.
To meet the user's moisture requirements, the ore is dried until its water content reaches approximately 0.5%.
It is then subjected to crushing and screening to produce ores of different particle sizes.
Finally, the finished product is packaged according to user specifications.
Every process requires sophisticated equipment and a strong sense of responsibility to customers to ensure the production of qualified products.
