In some ores, calcite is present in moderate quantities along with silicates. In such cases, silicates or sulphides associated with calcite are floated using amine surfactants (Hanna 1975).All these experiments were performed at alkaline pH; if silicates or sulphides were present in the ores, these were floated before the separation of scheelite and calcite was performed.
