Source of raw material for high-grade pyrite

  The average ore sulfur content of pyrite mine is about 35%, Some mines has rich veins of sulfur its content is about 46%, but proportion of such mines are very few. Ore will have a certain proportion of stone，mud and other debris, So only after the washing, sorting out miscellaneous stone and drying that the sulfur content can increase to about 48%, and then they become qualified raw materials for processing to be high-grade pyrite. Because few mines have high sulfur content of pyrite resources, so users usually have to purchase from several mining enterprises.
