Copper electrolyte purification refers to purifying and removing impurities from the electrolyte to meet the requirements of copper electrolysis. Copper electrolyte often contains impurities such as arsenic, antimony, and bismuth. These impurities will affect the purity of copper and electrolysis efficiency. Therefore, the electrolyte needs to be purified. The materials provided by Kingshan can highly selectively remove antimony and antimony from the copper electrolyte. bismuth and other impurities to achieve the purpose of deep purification.
