In the last decade, paste 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 acceptance of paste backfill plants, especially in bulk mining, has been extensive for several years since the first modern plants were constructed in Canada. Extensive research work in the early 1990s resulted in advances in the preparation and transportation of paste.

The advantages of paste backfill over hydraulic fill include reduced binder consumption, slimes handling, stope preparation and surface disposal coupled with productivity improvements associated with an increased mining cycle.
