Washing Thickener In Tailings Recovery Optimal Performance

Paste thickener benefits for soda ash: liquor recovery, mine backfill and surface stack J Johnson WesTech Engineering Inc., USA L Webb WesTech Engineering Inc., USA Abstract The benefit of paste and thickened tailings (P&TT) was used for decades in the trona industry with a high-density type thickener installed as early as 1994
