DOP Submersible dredge pumps

Residue storage facility of slimes cleared by DOP150

PROJECT SUMMARY
Location: High Mineral Sands mine, South Africa
Period: Q1-Q2/2020
Product type: DOP150 with sand mining head
Contractor: Dredging Africa
Residue storage facility of slimes cleared by DOP150

The DOP150 was called in to clear a toe paddock around the Residue Storage Facility at a mine in South Africa. The material in theses toe paddocks consisted of slimes, which had to be removed as the storage facility itself had to be extended over the toe paddocks.

The excavator & DOP Dredge pump combination

The challenge was that no conventional earth moving equipment nor a suction dredger could be used in the area. The solution was adapting an existing excavator from the fleet : its boom was extended, and its hydraulics were altered to be able to power the DOP dredge pump directly.

DOP150 with sand mining head

The excavator & DOP Dredge pump combination was used successfully : the slimes from the paddocks has been pumped back onto the existing Residue Storage Facility.

The task was completed in 5 months’ time : and although the site is situated in a highly abrasive sand environment, the DOP pump never failed and no break downs were experienced.
