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, …

mining and processing. Where coarse ores are processed, such as coal or hard rock, this buffer may be an ore stockpile or silo. For wet-mining processes, e.g. dredging or hydraulic mining, or where fine ores are slurried close to the mining face, a surge-bin is used to contain the plant feed and smooth out the variations in mining rates.
