METHOD FOR EXTRACTING GOLD FROM PYRITE CONCENTRATE |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: method for extracting gold from pyrite concentrate involves crushing of a concentrate and its pulse impact loading for separation of gold from concentrate particles. Crushing and impact loading is combined by performing the movement of the concentrate particles with fineness of 0.5-2.0 mm at the speed of 80-100 m/s with further collision of particles with an obstacle. Obstacle plane is located at the distance of 0.4-0.6 m from the accelerating device perpendicular to particle movement direction.EFFECT: improving gold extraction from pyrite concentrate.5 tbl, 5 ex |
