10.02.2021Scheelite is often associated with fluorite and calcite in nature. Due to their similar surface chemical composition, the difficulty of scheelite flotation is the separation of scheelite from Ca-containing minerals. Thus, NaCO 3 (pH regulator) and Na 2 SiO 3 (inhibitor) must be added before flotation to improve selectivity.

The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six decimal orders of magnitude of the particle size, is carried out in several steps.
