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 ...

Outotec solutions for tailings dewatering

Landfill and backfill technology Outotec paste technology is a modern way to handle and store tailings from mine operations in a more environmentally sustainable way. Outotec solutions in this area consider both paste disposal for landfill and stabilized backfill to mine. Outotec backfill technology also handles traditional dry backfill solutions. Dry Stacking of tailings

No option to store water within a dry stack facility. A conventional tailings facility, designed to store water, can provide a mining operation with a buffer (e.g. storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water.
