This invention relates to an apparatus and method for removing an underflow stream and in particular to an apparatus and method for removing an underflow stream from a separator. The invention has been developed primarily for use with a mineral particle separator.

One aspect of the invention provides an apparatus for removing an underflow stream from a separator, said separator having a discharge outlet for discharging said underflow stream, said apparatus comprising: a source of pressurised fluid; a first conduit for fluidly connecting said pressurised fluid source to said discharge outlet such that said pressurised fluid is directed to impede the flow of said underflow stream in said first conduit, thereby creating a fluidisation zone, and a second conduit fluidly connected to said first conduit so that material from said fluidisation zone flows into said second conduit for removal from said apparatus.

A mineral recovery system for use in a mining operation is described. The mineral recovery system includes a mining operations model generated based on inputs of sensed conditions, wherein the mining operations model incorporates a thickener sub-model and a material sub-model. The mineral recovery system includes a thickener controller to issue commands based on the mining operations model. The mineral recovery system includes a thickener having a process water. The thickener also includes an underflow output provided with an underflow controller to adjust outflow of thickened slurry from the thickener based on issued commands. The thickener further includes an overflow output to dispense clarified water from the thickener.
