Measurable variables in copper Electrowinning and their relevance to predict process performance

This paper presents a comparative review of process variables and anomalies that affect directly the Key Process Indicator (KPI) in copper Electrowinning (EW) processes. Considered KPI are product quality, production level, and specific energy consumption. It shows industrial techniques used for measure and monitoring those variables and generate a discussion about their importance on global process evaluation. The review shows that it is important to improve the measurement of electrolyte variables to know the real status with precision and quickness to improve the process behavior and production.
