What is Cyanex 272?

CYANEX® 272 is a dialkyl phosphinic acid extractant widely used for the separation of cobalt from nickel to produce high purity cobalt salts and cobalt metal. Since the active component of CYANEX® 272 extractant is a phosphinic acid, metals are extracted through a cation exchange mechanism.

What is feed solvent?

Solutes are separated based on their different solubilities in different liquids. The solution which is to be extracted is called the feed, and the liquid with which the feed is contacted is the solvent.

What is solvent extraction method?

Solvent extraction is a process in which compounds are separated based on their relative solubilities. This treatment method involves using a solvent – a fluid that has the ability to dissolve another substance. Solvent extraction is used to separate hazardous contaminants from sludge and sediments as well.

What Cyanex 923?

CYANEX 923 extractant is a liquid phosphine oxide which has potential applications in the solvent extraction recovery of both organic and inorganic solutes from aqueous solution, e.g. carboxylic acids from effluent streams and the removal of arsenic impurities from copper electrolytes.

What is solvent to feed ratio?

For a given feed mixture, required degree of extraction, operating pressure and temperature, and choice of solvent, there is a minimum solvent-to-feed ratio which corresponds to an infinite number of contact stages. The maximum solvent-to-feed ratio is thus that which puts the mixture on the phase boundary.

What are the 7 ways to separate mixtures?

What are the 7 ways to separate mixtures?

  • Handpicking.
  • Threshing.
  • Winnowing.
  • Sieving.
  • Evaporation.
  • Distillation.
  • Filtration or Sedimentation.
  • Separating Funnel.

What four methods can be used to separate mixtures?

Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.

What raffinate means?

: a liquid product resulting from extraction of a liquid with a solvent also : the less soluble residue that remains after extraction (as in refining lubricating oil)

How do you find the minimum solvent to feed ratios?

Minimum solvent-to-feed is determined by extending the tie-line that runs through the feed point until it intersects the segment connecting Vb and Lb. This intersection is the point Pmin, an operating point at minimum S/F. The line is then extended back across the envelope to the extract side.
