Sorry, I should say more like angle of deposition. This slurry will be a non segregating batch, so initial deposition i think we can assume it will be undrained (not too sure on this), then it will be given ample time to dry out before another lift will be deposited on top of this.
I was just wondering if anyone knew what a good approximate angle of repose for a potash fine tailings slurry that will be deposited with a 35% solids by mass. These tailings consist of 59% silt and 41% Clay.
