Do you all know anything about the EMEW swirl electrodeposition technology?

Know a lot, apply little; what’s the problem?

It’s been used quite a bit; I’ve worked on it for five years

The indicators from a chemical perspective are impeccable. However, what is obtained through cyclone electrowinning are copper tubes. . . . . . This means that copper ingots or copper sheets must be melted before they can enter the sales market.

In the process of electrowinning copper, can the copper produced by swirl electrowinning achieve 4 nines? Is it possible to carry out leaching and purification followed directly by electrowinning? Is there any that was electrodeposited after L-SX?

The purity of the product has little to do with the electrolysis method

Cyclone electrowinning/turbulent electrowinning share the same electrochemical principles as conventional electrowinning; in both cases, the flow of the solution is intensified to create a turbulent state, thereby enhancing mass transfer and eliminating the concentration polarization phenomenon associated with electrowinning. As a result, this method is suitable for treating solutions with low concentrations. Its several notable advantages are: (1) the ability to handle solutions with low concentrations of the main metal and high levels of impurities, which cannot be processed by conventional electrowinning methods； (2) The electrolyzer is a sealed tank, allowing the acid mist and waste gases generated to be collected and treated centrally; this represents a breakthrough over traditional processes in terms of operating conditions and environmental protection ； (3) Modular design, with low requirements for workshop infrastructure, easy to assemble and disassemble, and a very short construction period ； (4) It can operate at very high current densities, resulting in a production capacity per unit cathode area that is several times higher than that of conventional electrowinning. But it also has its own disadvantages: (1) It uses a stainless steel tank and a titanium-coated precious metal anode, resulting in higher costs ； (2) Due to the sealing requirements of the equipment, operating the loading and unloading slots is somewhat more complicated than in traditional electrowinning (but it has significant advantages if metal powder is to be produced without the need for slot opening and closing operations). In summary, it is suitable for processing small-scale, high-value metals.
