Separation of nickel and cobalt from calcium, magnesium and manganese by solvent extraction with synergistic mixtures of carboxylic acids
The potential use of synergistic mixtures of reagents for the solvent extraction of nickel (and cobalt) from lateritic leach liquors was pointed out in the early 1980s by Grinstead, who used dinonylnaphthalene sulphonic acid in conjunction with some 2-pyridyl compounds for the recovery of these metals from slightly acidic solutions1,2. Shortly thereafter, studies at Mintek revealed marked syner...
متن کاملSeparation of Nickel and Zinc Ions in a Synthetic Acidic Solution by Solvent Extraction Using D2ehpa and Cyanex 272
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(2-ethylhexyl) 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% wh...
متن کاملSolvent extraction and stripping of zinc from synthetic chloride solution in presence of manganese and cadmium as impurities
In this research work, solvent extraction and stripping of zinc ions from a Zn-Mn-Cd-bearing solution was investigated using D2EHPA as the extractant in a chloride medium. The efficiency of the extraction and stripping stages was evaluated separately, and different parameters such as the pH, extractant concentration, reaction temperature, and contact time were studied. Based on the results obta...

15 صفحه اولSeparation of Manganese and Iron from Reductive Leaching Liquor of Electric Arc Furnace Dust of Ferromanganese Production Units by Solvent Extraction
Electric arc furnace dust (EAFD) of ferromanganese production units, in the form of slurry, contains tar, alkalies, manganese, zinc, iron, silica, calcium, aluminum and other elements. A hydrometallurgical route based on solvent extraction technique was investigated for selective separation of manganese from the dust. Leaching of the EAFD resulted in an aqueous feed containing 4 g/L of manganes...
