| 摘要 |
The invention relates to a settler and a method for decanting mineral slurries. The settler (10) comprises a tank (11) for holding and decanting a body of slurry (15 & 16) to form a thickened slurry as a lower layer (15) and a clarified liquid as an upper layer (16), the tank having a side wall (34), a bottom (36) and a top (14), an outlet (18) for the thickened slurry at the bottom of the tank, an outlet (19) for the clarified liquid layer near the top (14) of the tank, a slurry inlet means (12) near the top of the tank for introducing fresh slurry into the tank, the slurry inlet means having a slurry opening through which fresh slurry joins the body of slurry in the tank, and a stirrer (20) having a generally vertical axis (30) around which the stirrer rotates or reciprocates. The slurry opening (12C) is displaced laterally relative to the generally vertical axis (30) of the stirrer (20) and the slurry inlet means is configured to allow the fresh slurry to enter the slurry body without accumulating solids from the fresh slurry at the slurry opening.
