Tailings rate of rise
Web26 Mar 2024 · The key to the success of this method is discharging secondary flocculated tailings at a low rate such that the rate of rise of the tailings surface is no more than 1-2 m per year. This maximises the drying and consolidation time and shear strength development for each deposited layer of tailings. Summary Web26 Jul 2024 · For a given stack footprint, the capacity of the stack in terms of tonnes of tailings it can store is directly proportional to the beach slope. If you predict 4% but only get 1%, then the stack will store only one-quarter of the tailings that you were supposed to design for, a major problem.
