| titleOfInvention | Method for separating solids from a tailings slurry |
| abstract | The invention relates to a method for separating solids from a tailings slurry that has a solids content of from 25 to 70% by weight and comprises sand particles and fines particles with a sand to fines ratio (SFR) of from 0.5:1 to 5:1, in which the fines particles comprise clay. The method involves adding to the tailings slurry a clay decoagulant reagent (DGR) and a flocculent. The method comprises at least one first mass flow (MS1) of the tailings slurry (TS) which flows to at least one first mixing region (MRI) containing at least one agitation means (AGI), optionally at least one second mass flow (MS2) flowing the tailings slurry (TS) from the at least one first mixing region (MRI) to at least one second mixing region (MR2) containing at least one agitation means (AG2). The tailings slurry (TS) is flowed from the at least one first mixing region (MRI) and/or optionally at least one second mixing region (MR2) as at least one conditioned tailings stream (CTR) which is separated into a solids rich phase and a solids depleted liquor. The method is controlled by of at least one item of information (11) associated with at least one first mass flow (MS1) and is directly or indirectly selected from the group consisting of the sand to fines ratio (SFR); the solids content; the specific gravity; the clay content and the flow rate of the tailings slurry (TS) in the at least one first mass flow (MS1), optionally at least one item of information (13) associated with fluidity measurements (FM1) showing any change in fluidity of the tailings slurry (TS) in the at least one first mixing region (MRI), optionally at least one item of information (14) associated with fluidity measurements (FM2) showing any change in fluidity of the tailings slurry (TS) in the at least one second mixing region (MR2), at least one item of information (15) associated with (15a) the at least one conditioned tailings stream (CTR); and/or (I5b) components of the at least one conditioned tailings stream (CTR) separated therefrom, wherein (15a) is associated with changes to the structure of the conditioned tailings stream (CTR) and (I5b) is associated with changes in at least one of the group selected from solids/liquid separation rate; volume of released liquid; turbidity of released liquid; and moisture content of separated solids. |
