A significant improvement of scheelite recovery using
May 10, 2017 The tailings of the scheelite flotation plant are pumped into a buffer pond. Lime (as a flocculant, 20–30 t/d) is added to the buffer pond to combine with the other tailings streams and then be pumped to the main tailings dam, where the fine tailings of scheelite flotation combine with the coarse fractions of solids to increase the settling rate.
