METHOD OF MINERALS JIGGING IN MAGNETIC FIELD Russian patent published in 2011 - IPC B03B5/10 B03C1/00 

FIELD: process engineering.

SUBSTANCE: invention relates in rigging performed in dressing placer products by specific weight and magnetic properties using magnetic fields. It may be used for gold extraction from dressing placer products with high content of magnetic materials. Proposed method comprises feeding initial material, producing natural bed, separating materials by density and magnetic properties and keeping said bed loosened. In rigging zone, pole-changing magnetic field is induced with frequency controlled by DC sign-variable source. The latter is made up of electronic thyristor circuit with DC source signs changing generator.

EFFECT: higher efficiency of dressing.
