Tailingsfo Thickened Tailings Storage - A discussion
2021-1-4 · In conventional tailings deposition the beach slope is very low, often around 1% (less than 1 degree) and facility design can be flexible if there is a slight variation in this parameter. However, for thickened tailings where the variation is often greater with increased beach slopes, this can have a big impact on embankment design heights.
