The coexistence of massive and powdered black sludge, Fe–Mn-weathered amorphous aggregates slime, greatly influences the floatability of rare earth minerals. Three types of flowsheets, gravity concentration, magnetic–gravity concentration, and gravity concentration–flotation, were used industrially (Xiong and Chen, 2009; Yu, 2001).
