Dredge Application: copper mine in the American Southwest rented SRSC’s Rotomite-6000 CD (“R6CD”) to restore the mine’s basin capacity without stopping mine processes, an ideal application for hydraulic dredging. The customer’s plastic-lined tailings dam collects outflow from various processing facilities. The slurry is acidic, with lye added to balance ph levels. A floating pump transfers water and material from a small catch basin into a large permanent tailings impoundment pond. The limited ability of the customer’s floating pump to pull in slurry led to an undesirable build-up of solids, which reduced the tailings impoundment pond’s holding capacity. The customer wanted to restore the pond’s capacity to original levels without stopping mine processes or damaging the pond liner.
