In the last two decades, pastefill technology has progressed from a research-based backfill idea to a widely accepted, cost effective backfill method with the potential to radically change the way tailings are disposed of on surfaces. The advantages of pastefill over hydraulic fill include reduced binder consumption, slimes handling, stope preparation and surface disposal coupled with productivity improvements associated with an increased mining cycle.
