CLAY FLOTATION OF TAILINGS |
| 摘要 |
A process for treating and dewatering tailings comprising fine clay minerals, fine silt minerals and water is provided, comprising treating the tailings with a sufficient amount of a clay surface reagent to selectively modify the surface properties of the fine clay minerals; subjecting the treated tailings to froth flotation to float a portion of the fine clay minerals and form a clay froth layer and froth flotation tails having a reduced fine clay minerals content; and recovering the clay froth layer and subjecting it to dewatering. |
