Separation of Copper-Molybdenum Flotation Concentrate by Superconducting High-Gradient Magnetic Separation

Separation of chalcopyrite from molybdenite is currently mainly carried out by flotation, but this process costly because the extensive use inhibitors. This study briefly describes a 7.0T/100CGC low-temperature superconducting magnetic separator and discusses its separation principle as well effect induction on molybdenite. A molybdenum (Mo) concentrate assaying 6.00% copper (Cu) 19.01% Mo was magnetically sorted using diamond-shaped steel rod medium mesh at feed concentration 20% pulp flow rate 5 L/min Cu-Mo flotation with 88% particles smaller than 23 ?m separator. 0.46% Cu 16.28% finally obtained roughing (1.3 T)-cleaning (5 T) process. Similarly, performed to separate bulk concentrate, produced 19.64% 0.03% 18.52% 0.39% particle size less 0.074 mm. At 7 T, velocity L/min, grade recovery in product were 81.59%, respectively, whereas non-magnetic 1.52% 90.07%, respectively. Superconducting has potential applications for removing concentrates, separating concentrates.
