Hydromining and Tank Cleaning
Digester Clean Wastewater Treatment Plant, Boliver SA
The process of emptying and cleaning the digester involved using specialised pumping equipment provided by NPE. This was suspended from a 60-ton crane for efficient operation and flexibility of movement. The pump used for this task was a heavy-duty hydraulic unit specifically adapted by NPE to handle these projects. To remove the contents of the…

To expand the storage capacity of the Sediment Pond at Koolan Island, NPE were engaged to undertake a Hydromining campaign to remove approximately 3,600m3 of settled solids. NPE used a high-pressure water technique to break down the compacted material into a slurry via water sourced from three Hydromining cannons on the sediment pond’s external perimeter.…

Over time, water ponds that are gravity fed become full of tailings, which reduce their storage and surge capacity. These ponds require tailings to be removed periodically; however, excavation methods can present some risks of liner damage. Hydromining is the perfect solution. It agitates the solids (tailing build-up), pumping it back to the tailings dam.…

During the February Processing Plant shutdown, maintenance tasks were carried out simultaneously on Nickel and Copper Thickeners. Tool time requirement was 96 hours, and all four thickeners were required to be emptied and cleaned within a 12-hour shift. Our client cannot achieve this in-house; therefore, historically, they only attempted to maintain 1 or 2 thickeners…
