Refinery Optimization

copper as service

Copper Refinery Bleed

The safest, most efficient copper liberator circuits have emew inside.  The unique helical flow produces high-grade salable copper cathode with no acid mist or arsine, high energy efficiency and improved impurity control with the ability to recover acid and nickel from the de-copperized bleed stream.

Silver Refining

The fully enclosed and automated emew silver process produces high purity silver powder in the presence of impurities, with smaller footprint, enhanced security, lower working capital and immediate release of gold and PGM’s.  

Copper solvent extraction

Copper SX-EW Bleed

Recover high-grade saleable copper cathode from SX-EW bleed streams with emew electrowinning to enhance leaching performance and improve overall copper recovery from the heap.
