Our vision is of a sustainable future based primarily on the circular economy.
To help fulfill this vision, our mission is to deliver clean technologies for metal recovery under the emew System. This is a complete suite of hardware, patented technologies, and know-how accumulated over nearly 30 years, incorporating the principles of green chemistry and the invention of the original “vortex” electrowinning technology. As a result, we create value in metal recovery whilst meeting important ESG obligations.
How about selectivity towards different metals? I’m trying to recycle vanadium from a mixed solution with V(V) and Fe(III) in order for it to be reused as a flow cell reagent, but they seem to either come out as solid together or both stay in the solution.
Chelates in solvent extraction. Can't explain more but I worked at a refinery where we were selectively extracting Cu from a solution with other dissolved metals. We used an organic extractant that selectively extracted Cu . The selectivity was 2000 Cu: 1 Fe..
The word "Saleable" is misspelled, it's spelled "salable" is generally pronounced Sell-able, or sale-able. meaning fit for sale. If you're going to do this kind of work, at lease pronounce the words right
I have a doubt in the VAT leaching process As per your mentioned example of gold using sodium cyanide(0.01%) and using lead nitrate U said we used lead nitrate to minimize the consumption of cyanide in the reaction Won't that form lead cyanide complex ? Which would consume the cyanide and not let the formation of gold cyanide
In the case of pollution reduction or remediation can this be used to remove things like mercury, arsenic, selenium, lead, or cadmium, to name a few? What about iron, nickel, or aluminum compounds?
Good info thanks! Can you answer this? If I have mixed metals and want to refine them within a mixed electrolyte solution with multiple batteries / anodes / cathodes, what issues will I run into? Can you provide any info?
i thought they did i basically got that from the explanation that its running a electrical current through a cathode and anode placed into a liquid solution of particular metal concentrations to attract the desired metal to the cathode.
Already doing that.Producing .998 pure. Can’t find a buyer that will pay bare bright rate because it isn’t wire. Much needs to be done with the traditional nature of scrap metal buying and selling. I have high purity material, basically elemental and I have no buyer because they have never seen it. So therefore it must be flawed. Great idea and all but there is no market for it beyond commercial mining SXEW plant produced products. You show up at a yard and they XRF assay the piece they find it interesting. But more of a curiosity but not buyable because they don’t think their high purity buyers will purchase it. Been there saw that movie.
