FRC Systems International has been awarded a contract for the manufacturing and delivery of a dissolved air flotation (DAF) mining waste water treatment system for a copper mine in Chile.
FRC Systems will install the 450m3/hr DAF system at the port, where copper concentrates will be loaded into the vessels.
The DAF will receive the wastewater to be treated from overflow of thickeners of copper concentrate, which will be combined with wastewater from the scrubbers.
Scrubber wastewater will be treated to precipitate H2S previously oxidized with ferrous sulfate.
The solids are first sent to a lamella plate settler for solid removal and then sent to DAF systems for final solids removal of the fine dispersed solids prior to discharge.
