The original and patented emew ‘cyclone’ or ‘vortex’ electrowinning technology was developed by emew in Australia in 1992. Over the past 25 years, emew has continued to push the boundaries of electrowinning by continuously improving the emew technology with advanced designs for plating, powder, polishing and hybrid systems including a suite of complementary clean technologies catering ...
Metal Powder Production Capabilities. A significant achievement in powder metallurgy is the ability to produce metal powders with customized densities, particle size distributions (PSD) and microstructures or morphologies. The emew team has done just that with the patented and proprietary emew powder cell.
The emewPlate cell is used for more concentrated electrolytes generally when the target metal concentration is greater than 10 g/L. The emewPlate cell is often used for recovering copper, nickel and tin cathode in a variety of applications including mining, refining, and recycling. The emewPlate cells can also be paired with solvent extraction (SX) and ion exchange (IX) when pre-concentration ...
The most advanced liberators for copper refineries are emew electrowinning cells. The unique cell design delivers high-grade saleable cathode (even from secondary liberators) improved current and energy efficiency, improved copper and impurity control over a range of concentrations, recycling of acid and reduction in effluents.

20-06-2018· In this short video, we answer some most frequently asked questions about production rate and capacity of emew plating and powder cells.
Copper refineries are taking advantage of these benefits and retrofitting conventional copper liberator cells with advanced emew liberator cells. A recent example is Hindustan Copper Limited , a government of India enterprise that installed emew for copper and nickel recovery from refinery bleed streams.
The polishing cell uses a proprietary high surface area cathode, this type of emew cell can recover metals from 1 g/L down to less than 5ppm. Q2: What is the flow rate through each cell? A2: The flow rate is approximately 6000 L/hr for the plating and polishing cells and approximately 2000 L/hr for the powder cell.

01-05-2013· re: the emew cell Post by Captobvious » May 1st, 2013, 3:14 am If this is what you are referring to, then I can imagine it not being discussed as everything I've seen shows it to be in use by "the big boys" of refining and not really for the hobbyist.
CNPC POWDER electrolytic copper powder is produced from the mixture of sulfuric acid and copper sulfate as electrolyte with electrify. As raw materials, the materials melt into liquid after high heating and become tiny particles after water or gas blowing. Electrolytic copper has a high purity of Cu content 99.7%.The powder has low apparent destiny and a dendritic powder shape.
For low ore grades, emew electrowinning can be coupled with solvent extraction (SX) or ion exchange (IX) for an economically attractive modular process plant. For smaller scale high grade mines emew can rapidly deploy pilot or compact commercial plants in as little as 3 months so you can start generating revenue quickly and effortlessly expand to fit your growing production requirements.
An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.
