Mine Paste Fill
An open pit expansion to two underground mines, required a new paste backfill system to produce a cemented backfill used to fill underground stopes. The paste backfill is composed of dewatered mill tailings and slag/cement binder mix that is pumped or allowed to flow by gravity. This part of Canada is both a severe cold climate and remote location for such a project requiring specific design consideration including:
-precast concrete work
-modular design based on shipping dimensions
-heat tracing and insulation of piping and bins
-building and entry space heating
The facility included a 360 t/h paste plant, booster station and binder storage facility.
Consultec, in partnership with an equipment supplier, designed the plant and procured the process equipment, plant services/utilities, electrical equipment and construction bulk materials.
