MINERAL DRESSING METHOD USING ELECTROMAGNETIC FIELD REACTION AND MINERAL DRESSING DEVICE THEREOF

摘要

Disclosed is a method for beneficiation of a target mineral which enables easy selection of a target mineral particle, particularly a quartz, with a reaction difference between minerals reacting with electric field energy and magnetic field energy, and an ornamental device used therefor. According to the present invention, there is provided a method for optically mining a mineral for collecting desired mineral particles, comprising: a crushing step (S1) of crushing a mineral mass into mineral particles; (S2) of separating the crushed mineral particles into conductor mineral particles and non-conductor mineral particles through the crushing step (S1); A magnetic field selection step (S3) of separating the conductor mineral particles separated in the primary electrification step (S2) into magnetic mineral particles and non-magnetic mineral particles; In the magnetic field selection step S3, the non-magnetic mineral particles are separated into the target mineral particles and the other mineral particles, and the secondary mineral selection step S4 is performed to selectively collect the target mineral particles. This can be achieved through the optical concentrator.
