Silver Refining

Silver refining demands technology that can offer the highest purity coupled with advanced security features and low working capital or Work-in-Progress (WIP). Silver purity exceeding 999.99 (also referred to as 5N’s) can be achieved with emew. No other technology can produce this purity of silver in the presence of impurities such as copper, lead, selenium and others.

A completely enclosed system, emew eliminates acid mist and promotes a safer environment for operators and management.  The emew silver refining system is low maintenance, worry-free, and fully automatic with minimal labour requirements.

The high purity silver powder is automatically harvested using a flush through technology to a single collection point ensuring the utmost security, with no losses and simplified metallurgical accounting. A single batch can be processed in as little as 8 hours significantly reducing working capital or WIP which in itself can pay for the upgrade to emew.

Enhanced security, improved metallurgical accounting and significantly reduced working capital make emew the ideal fit for your silver refinery or metal recovery operation. Do you have little space for an expansion or retrofit? These systems are compact with 1000 kg/day production capacity fitting into as little as 25 m2 (269 ft2).
