Jun 15, 2019 · Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO 4) from fluorite, apatite, and silicates. Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult.
