Selective flotation of scheelite from calcite and fluorite ...

Mar 01, 2015  1. Introduction. The flotation separation of scheelite from other calcium-containing minerals such as fluorite and calcite, is problematic, due to their similar solubility and the same active Ca 2+ site for interaction with anionic collectors (Rai et al., 2011).Thus, using a single type of collector is unlikely to achieve selective flotation of scheelite from fluorite and calcite.
