Solvent Extraction

Solvent extraction is a liquid-to-liquid process to remove minerals from a pregnant or loaded leach solution. Solvent extraction involves the extraction of metal or minerals from an organic solution. Additionally, the corrosive nature of these fluids can be detrimental to standard valve and measurement technology.

Better living through chemistry: chemical extraction

Solvent extraction is used to concentrate and purify metals from mined ores; the company has tapped into the potential of digitalising this process with a platform called SolvExtract. As the technique involves leaching soluble metals from the ore and separating them via solvent extraction chemistry, the process also stands out as significantly changeable, with varying

Flow Measurement of Organic Solvent in Solvent

The principal application of solvent extraction in the copper beneficiation process is the selective separation of copper ions with the use of an organic solution. Measuring the flow rate of the organic solution is crucial in the process and can be challenging, as the selection of hydrocarbons include solvents such as benzene, kerosene and chloroform.

Solvent extraction of metals: Role of ionic liquids and

The extraction of metal ions using the solvent extraction method has been started in the 1950s with the extraction of uranium from its ores and later for tantalum and niobium, . Organic solvents such as xylene [27], kerosene [28], n-heptane [29], methyl-isobutyl ketone (MIBK) [30] and chloroform [31] are commonly used for the extraction process.

Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
