A Novel Chemicals' Scheme for the Flotation of Bastnaesite Ore
This invention is a flotation method for removing heavy earth metals from Bastnaesite ore. It works by reducing the flotation temperature to a cost-efficient level and simplifying the flow sheet. Results show that 80-90% REE recovery and <20% gangue recovery are achieved at 40°C-60°C, which yield a rougher concentrate of 30%~40% REO. The...
