Method of purifying copper electrolytic solution - Google Patents

A method of purifying a copper electrolytic solution circulated in a copper electrorefining system, wherein a portion of the solution is withdrawn and recycled to the system after purification treatment. The purification treatment includes the addition of a hydrosulfide to the withdrawn solution to generate only the necessary quantity of hydrogen sulfide gas required in the reaction.

What's the Best Way to Remove Copper from Industrial Wastewater?

The types of membrane filtration commonly used for copper removal include nanofiltration (NF), reverse osmosis (RO), and electrodialysis. Ultrafiltration (UF) can also be used, though its pore size range is too large to effectively capture copper ions on its own, so it must be used in combination with other treatment technologies.
