The China Hongxing sand mining process begins with the raw material extraction from the mine. The mined materials are sent into through vibrating screen for primary crushing. Then they will enter into the to be further crushed in the secondary crushing section. Ball mill is used to grind the crushed materials. Next is the gravity separation stage. According to the different gravity characteristics, the undesired materials will be removed from the zircon sand. The result is a concentrate suitable for refining and the tailings that have no economic value. Tailings are the materials left over from the ore processing facility after chromite has been extracted from the zircon sand. Tailings will be managed over the long-term at the mine site in a tailings management area.
