Field of application:
1. Power industry :
Pumping coal burning residues (ash, slag, FGD products, etc.), as high concentration slurries to the deposit area. One single pump can handle slurries over long distances (kilometres).
2. Minerals processing industry
Autoclave and reactor feeding, digester feeding, tailings disposal and other similar applications consisting of pumping high dense slurries, at high pressures and temperatures.
3. Mining industry
Mine dewatering, by raising water with high solids content and highly corrosive to the surface, in one single stage. This eliminates costly settling ponds and high maintenance low efficiency centrifugal pumps.
Hydraulic ore hoisting: after crushing and grinding the ore and mixing it with mine water underground, the ore slurry is transported to the surface. Hydraulic ore hoisting is a viable, cost-effective alternative to skip hoisting.
Mine backfilling: whatever backfill system is applied, GEHO pumps provides reliable transportation of slimes or classified tailings. At the surface, the pumps are used for transporting slurry from the preparation plant. Underground, the pumps are used for filling the stopes with high density backfill, to stabilize the soil.
