Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, …

Ore concentration is the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals in their pure form. In other words, it is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. Both physical and chemical means can ...

The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
