Fine Flotation Tailings Dewatering: Reducing Water ...

satellite deposit of highgrade gold mineralization was defined between 2009 and 2012. To support processing of this highgrade material, an 800 tpd mill with gravity and flotation concentrate recovery was built at a cost of USD 20 million. Production of underground ore began in Q3/Q4 2014, with name plate capacity achieved in Q1 2015.
