Research on Technology of Wastewater Treatment from Scheelite Flotation

Abstract:

Wastewater from scheelite flotation tailings slathered a lot of sodium silicate in the flotation process, a large number of silicate minerals residues remain in the wastewater, forming suspension bodies difficult to be naturally subsided. With high concentration of suspended substance and pH of 11 or more, this kind of wastewater belongs to unmanageable mine wastewater. Research shows that, pretreating the waste water with Sulfuric acid and calcium chloride, adjusting pH to 7-8 and adding polyacrylamide on flocculating-sedimentation combined can remove suspended solids effectively, offering theoretical basis for wastewater recycling and disposing mine wastewater, which is of great importance.
