Control of an industrial copper solvent extraction

A two level control strategy that stabilizes and optimizes the production of an industrial copper solvent extraction process is presented. The stabilizing layer consists of a multi-input multi-output controller or two single-input single-output controllers with additional four feedforward compensators that regulate the flow rates in the copper solvent extraction process.

2.7 notes.doc Topic 2.7 EXTRACTION OF METALS

The process can be summarised as follows:-copper ores are converted into solutions containing Cu 2+ ions using dilute sulphuric acid and a specialised bacterium-the copper ions are then reduced to copper using scrap iron: Cu 2+ (aq) + Fe(s) Cu(s) + Fe 2+ (aq) Advantages of this process:-it uses very little energy (although energy would have been used to make the iron)-it works on very low grade copper ores, including copper mining waste-iron is much cheaper than copper
