Abstract :
This paper presents a comparative review of process variables and anomalies that directly affect the key performance indicators (KPIs) in copper electrowinning processes. The KPIs under consideration are product quality, production level, and specific energy consumption. This paper describes industrial techniques used for measuring and monitoring those variables and discusses their importance for global process evaluation. The review shows that it is important to improve the measurement of electrolyte variables for a quick and precise diagnosis and better process behavior and production.
