Fig. 2 shows the flotation recovery results obtained when monazite and calcite are floated separately in single-mineral flotation tests using a collector dosage of 1 × 10 −4 M. A maximum recovery of around 90% was obtained for monazite at pH 9.0 while calcite recovery at the same pH value was only around 22%%.

Mineral Processing | SpringerLink

The run-of-mine extracted from the ground requires further processing in order to make a marketable product. This preparation is called mineral processing. Thus, ores must go through a number of different operations to obtain the final products: comminution or size reduction, size separation, concentration or beneficiation, and dewatering.
