One of the challenges in upstream tailings dam projects is to ensure allowable rate deposition pond (i.e., filling rate) while maintaining stability dam. This due fact that an constructed by placing dikes on top previously deposited soft tailings, which could lead a decrease because build-up excess pore water pressure. The main purpose this work investigate effects rates pressure and numerical ...

In this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. The effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. A software based experimental design approach (DX7) was applied to determine and mod...
