The Electrometals Technologies Ltd EMEW electrowinning technology has become a mainstream technology alternative to conventional electrowinning designs. Based on the principle of improved transfer of cations to the cathode through the use of forced flow in a tubular electrowinning cell, the EMEW design offers improved current efficiency, higher current density, a compact design which is fully enclosed allowing recovery of electrowinning gases along with operating flexibility.

EMEW technology has evolved over the past decade and now offers both plating (150mm diameter) and powder (200mm diameter) production cells. The plating cell is harvested in much the same manner as conventional electrowinning products whilst the powder cell design offers fully automatic operation using periodic flushing of powder product. The powder design has been proven effective and economic at removing metal values from solution to as low as 1ppm.

Electrometals are able to assist with leaching chemistry and can offer EMEW testing in Australia, Canada and Chile. Electrometals can confidently directly scale up EMEW plants from laboratory testing, and pilot units can be made available.

EMEW technology can be applied to economically recover quantities ranging from a few kilograms to many tonnes of product per day at competitive installation costs and class winning operating costs.
