David John Williams, in Ground Improvement Case Histories, 2015. 2.4 Beaching behavior of mine tailings. The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF.The tailings may be

2020-4-8 With a thickened tailings system, transport costs can be a big variable. Moving paste 500 m vs. 30 km can be a huge difference. However, a higher yield stress translates into less of a requirement for impoundment where the cost of the equipment would be insignificant compared to the costs on the deposition zone.

2020-5-7 At present, there are two main methods of tailing filling goaf: 1. Non-dewatered and cemented full tailings filling. This tailings disposal method mixes the dewatering tailings with cement and flies ash to form the filling aggregate. Then, the filling pulp is sent into the goaf by the pipeline armature, thus filling the goaf. 2.
