industrial copper solvent extraction process

A diagram of a full basicprocessis given in Fig. 1.6 to illustrate the common terminology. The incoming aqueous solution is called the feed.It is contacted with the (recycled)solventphase in a mixer-settler unit.Here we do not indicate the exact type of unit, but only its function (extraction…

It is contacted with the (recycled) solvent phase in a mixer-settler unit. Here we do not indicate the exact type of unit, but only its function (extraction), as commonly is done. Afterextraction and separation of the phases, the depleted phase becomes the raffinate and the enriched solvent phase becomes the extract or loaded (or pregnant) solvent.

Solvent Extraction Plants Thiele Diagram Amp Theoretical It has been explained in an earlier talk that solvent extraction in the copper industry isused to convert impure and frequently very dilute copper solutions into very pure and concentrated solutions from which pure copper can be extracted by a variety of means usually electrochemical.

Coppercan be extracted from non-sulfide ores by a differentprocessinvolving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilutecopper(II) sulfate solution. Concentration of thecopper(II) sulfate solution bysolvent extraction.

Thisprocessuses aqueous (water-based) solutions to extract and purifycopperfromcopperoxide ores at ordinary temperatures, usually in three steps: heap leaching,solvent extraction, and electrowinning. Heap Leaching is theprocessof using percolating chemical solutions to leach out metals. Heap leaching is very commonly used for low-grade ...

A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. Thisprocessuses aqueous (water-based) solutions to extract and purifycopperfromcopperoxide ores at ordinary temperatures, usually in three steps: heap leaching,solvent extraction, and electrowinning.

A two level control strategy that stabilizes and optimizes the production of anindustrial copper solvent extraction processis presented. The stabilizing layer consists of a multi-input–multi ...

Control of anindustrial copper solvent extraction processTo date, no advanced control strategies or systems have been reported in literature or known to be utilized in the plants. The control of thecopper solvent extractionand electrowinning processes relies on operators actively manipulating the setpoints for the basic level controllers.
