Method for reducing silver content in cathode copper

The invention provides a method for reducing the content of silver in cathode copper, and relates to the technical field of copper electrolytic refining, the method comprises the following steps: S1, pumping an electrolyte from a circulating tank to a head tank through a plate heat exchanger by using a pump; s2, the electrolyte in the head tank automatically flows into an electrolytic bath; s3, dividing the electrolyte in the electrolytic tank into a circulating tank and a supernatant storage tank; s4, removing particles of the electrolyte; according to the method, circulating filter pressing is conducted on the copper electrolyte, suspended solids in the electrolyte are separated out in time, and therefore the situation that silver enters cathode copper in a discharge precipitation and mechanical adhesion mode is reduced, and an important change is generated for increasing the copper electrolysis production benefit. 本发明提供一种降低阴极铜中银含量的方法，涉及铜的电解精炼技术领域，包括以下步骤：S1、电解液从循环槽用泵经过板式换热器打至高位槽；S2、高位槽内电解液经过自流进入电解槽；S3、电解槽内电
