EMEW is a world leading technology in the process of electrowinning. Through technical innovation, intelligent engineering and use of modern materials, EMEW has been developed as a hardware system which effectively ‘turbocharges’ an age old process. The result is a dramatic improvement in efficiency, significantly lowering cost and extension of potential uses well beyond its traditional marketplace.
EMEW Creates Value
The radical improvement in efficiency made possible through EMEW technology now allows our customers to complete precious metal recovery for metals previously not recovered or disposed to waste. The significant operating and capital cost benefits of the technology have altered the economies of scale for metal project development - creating viability where it may not previously have existed.
EMEW Enhances Value
Electrometals & the EMEW technology enhance value for its customers through a simple single step process for Precious Metal Recovery. In comparison with traditional methods, we offer:
- Reduced capital cost of your precious metal recovery process
- Reduced operating costs in a simplified flow sheet
- Accelerated return on capital
- Improved product purity
Applications
The application of the EMEW technology has been proven over a very wide range of applications - too many to reproduce in detail in this brochure. For more information about possible applications please contact us using details below. | | 
Broaden process options with EMEW
Due to its inherent simplicity and efficiency, the EMEW technology allows more direct and versatile options in the field of precious metal recovery through:
- Capability to process low metal concentration streams
- Higher productivity than conventional cells.
- Efficiency over a wide range of metal concentration.
- Higher tolerance of contaminants in solution.
- Capability of extracting a variety of metals.
- Capability of selective electrowinning of metals.
- Generally higher purity product.
- Production of either metal cathode or powder.
Reduce Technical Risk with EMEW
EMEW technology is:
- Simple to operate.
- Constructed with minimal moving parts.
- Easy and inexpensive to maintain.
- Modular and portable.
- Easy to expand or relocate.
- Does not use reagents or chemicals.
- Delivered as a complete facility. 
| | EMEW is safer
During conventional electrowinning of metals oxygen bubbles are produced at the electrodes. When these bubbles reach the surface they burst, liberating an aerosol of acid called mist, which can affect the health of operators, the environment and plant infrastructure. The International Agency for research into cancer (IARC) a respected international science group based in Europe, classified sulfuric acid mists as causing cancer in humans.
EMEW provides as an inherent design characteristic complete elimination of the release of acid mist into the workplace. The EMEW technology capture ALL gases that can be generated and makes them available for collection and safe disposal or reuse. This feature of EMEW provides significant improvements to the working environment.
The technology can be built into custom designs for specialised application in almost any configuration. Two standard models are currently offered:
The EMEW plating cell
- Current Density up to 1000 a/m2.
- Product is a high quality solid cathode.
- Serial or parallel arrangements of 6” (150mm) diameter plating cells.
- Only moving part is a process pump.
The EMEW powder cell
- Current density up to 2000 a/m2
- Product is an easily liberated metal powder.
- Harvesting process totally automated.
- Full PLC control provided.
- Serial or parallel arrangement of 8” (200mm) diameter plating cells. |
