Theextractionsection 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…Get Price
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
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.See Details ➤
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.See Details ➤

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.See Details ➤
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.See Details ➤

Solvent extractionis used to concentrate materials in an organic solution, while electrowinning is used to recover these pay elements. The two procedures are often conducted together. While electrowinning can be used with other processes, it is always used aftersolvent extraction.See Details ➤
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.See Details ➤
