Separation of nickel and zinc ions in a synthetic acidic ...

Solvent extraction was used to recover nickel and zinc from synthetic acidic solution. Many leaching solution and waste waters contain both zinc and nickel at the same time. Bis (2,4,4trimethylpentyl) phosphinic acid (Cyanex 272) and Di(2ethylhexyl) phosphoric acid (D2EHPA) were used to separate nickel and zinc. In the D2EHPA system, at equilibrium pH of 2, zinc extraction was more than 98% ...

Solvent extraction and electrowinning Wikipedia

Solvent extraction and electrowinning (SX/EW) is a twostage hydrometallurgical process that first extracts and upgrades copper ions from lowgrade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes using an electrolytic .

Solvent Extraction Utilized to Separate an Organic Mixture

The second main step in the solvent extraction is separating the acid, base and neutral compounds from the original solution. The basic concept behind this process is to remove the base then the acid then the neutral compound to come up with the mass of each compound in the original solution.

The metal ions are extracted from hydrochloric acid medium; the extract is scrubbed in two steps in order to remove copper and chloride ions, whereby zinc passes from Alamine 336 to LIX 54. Zinc is stripped from the extract by sulphuric acid; copper is recovered from the scrubbing solution with a suitable chelating reagent (LIX 860).

Solvent extraction (SX) has been the predominant method of copper recovery in mining applications. While solvent extraction processes are adequate for highgrade ores, selective ion exchange (IX) has proven more economical, particularly for copper recovery from lowergrade sources of copper (those producing pregnant leach solution grades less than about g/L).
