Dams in General - SANCOLD

Tailings dams (or slimes dams) store the waste product (usually fine crushed sand, or sometimes power station ash or coal waste), from mining or industrial processes. Although the dam's primary function is to store waste, they also contain and store water from the mining/ industrial process and stormwater.

Using the large diameter cyclone size, such as the 900 mm diameter, results in a fewer number of operating cyclones and possibly a lower capital cost. The 900 mm hydrocyclone can also produce an increase in the amount of +150 micron material reporting to the hydrocyclone overflow, and a decrease in the amount of -75 micron material in the ...

Backfill distribution system design - QueensMineDesignWiki

Introduction. Traditionally, backfill has been produced from one source—the milled waste ore from the mineral extraction plant. This fine material has been, and still is, the preferred source of backfill material although milling technology has resulted in a finer tailings product and backfilling has moved from cyclone classified tailings to full plant tailings and higher solids ...

Tailingsfo Deposition Methods of Tailings

Multiple outfall deposition (spigots) is the most common method used to fill a surface storage facility. For conventional storage facilities, multiple spigots help to control the geometry and location of the supernatant pond within the facility. This helps to prevent the pond encroaching the embankment and reduces the risk of loss of freeboard.

With regard to the hydrocyclones, these proved to be more efficient than the conventional cyclones, highlighting the benefits of the Cavex® hydrocyclone's laminar spiral inlet geometry. "The Cavex hydrocyclone increased the mass pull to the underflow, which resulted in increased production and reduced slimes to the tailings dam," he says.
