BMC: A Modulating Bar for Copper Electrowinning Designed for Heavy Duty and High Reliability

This works presents the research, development, and design of a BMC intercell bar for copper electrowinning following heavy duty and high-reliability guidelines. As a result, the configuration ensures a low-maximum temperature with high-temperature rated connectors. These properties guarantee the hardness and integrity of the contacts and consequently its lifetime. Some key performance indicators include: control and balance of the cathodic current densities, short circuit protection, and bypass of weak contacts. Further, it has the unique property of hot swapability for replacing impaired connectors. Thus, the Availability of the intercell bar under typical electrowinning operating conditions is ensured.
