Get PriceTheextractionsection of thesolvent extractionplant consists of a number of mixer-settlers in series. The aqueous leach liquor flows through these counter-current to an organic stream which is made up of LIX 64N dissolved in a kerosene carrier, and thecopper…
Coppercan be extracted from non-sulphide 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 sulphuric acid to produce a very dilutecopper(II) sulphate solution. Concentration of thecopper(II) sulphate solution bysolvent extraction.

Forcopperoxide ore, electrowinning is the final stage in theprocessof hydrometallurgy, in which concentratedcoppersolution from the heap leaching andsolvent extractionprocesses is used as an electrolyte; an electric current is applied through an inert anode, resulting in the plating ofcopperonto 99.9% purecoppercathodes.
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…
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.

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.
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.
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 ...
