Supervisory Control Project of a Copper Solvent

2006-9-1  The motivation of this research is to develop a supervisory control system for an industrial copper solvent extraction process. This research has been planned in different stages. The first one was the design and commissioning of a SX pilot plant, where most of the operating variables are measured and/or controlled, such as organic and aqueous flow rates, levels and conductivity.

plc control of sx plant for copper extraction

SX-EW is a two-stage hydrometallurgical process that first extracts and upgrades acid-soluble copper from low-grade waste dumps, using dilute sulphuric acid, followed by extraction and upgrading of the leached copper solutions into an organic solvent mix containing a chemical that selectively reacts with and removes the copper.

A Monitoring System for the Copper Solvent

2003-10-1  Solvent extraction isotherms are determined experimentally and are dependent on the copper concentration of PLS, the extractant concentration and the sulphuric acid concentration of the aqueous phase. The process can be monitored by comparing actual copper mass flow rates to theoretical copper mass flow rates.
