Pectin is a highly efficient flotation depressant that can achieve good flotation separation between scheelite and calcite in the pH range of 7–9. When the pH is 7.5, the recovery of calcite is drastically reduced to only 4.56%, while scheelite still has a high flotation recovery (71.01%) in the presence of pectin.
