A New Process for Cobalt Nickel Separation teckextraction is achieved using a synergistic mixture of Versatic 10 and LIX 63 There are two basic steps involved, as in any solvent extraction process extraction and stripping A third step, scrubbing, may be needed where the manganese impurity levels in feed solution are particularly highUS3971652A Ammoniacal extraction of copper from metallic ,The copper in copper dross appears to be elemental or combined copper, for example as copper sulphides or arsenides, embedded in a matrix of de copperized metallic lead and it has previously been believed that extraction of this copper using conventional extraction agents would be difficultFacilitated transport of copper in bulk liquid membranes ,The liquid liquid extraction of copper(II) using a novel extractant LIX 984N (a mixture of 5 nonylsalicylaldoxime and 2 hydroxy 5 nonyl acetophenone oxime) was carried out Following the liquid liquid extraction, coupled uphill transport of copper(II) across a bulk liquid membrane containing LIX 984N as carrier was performedCognis Corporation Mining Technology | Mining News and ,COGNIS, supplier of LIX®Reagents and inventor of copper solvent extraction (SX), has been the recognized market and technology leader for more than 45 years Independent studies show LIX® Reagents are 10 – 25% more efficient than the competitive products and are used to produce over 60% of the world’s SX copper cathodeSeparation of Copper and Nickel by Solvent Extraction ,Separation of copper and nickel by liquid liquid extraction from aqueous solutions was studied using LIX 664N in kerosene as solvent Both metals were taken in their sulfate form and ratio of copper to nickel in feed solutions was maintained as 10 1 LIX 664N concentration in kerosene was varied from 10% to 40% (v/v) and its effect was studied on percent extraction of copper and nickel for .Extraction and Enrichment of Copper by Liquid Emulsion ,Process intensification using liquid emulsion membranes (LEMs) for extraction of copper has been studied in this work In LEM process the extraction and stripping processes are combined in one stage The solubility of the solute or the chemical affinity between the solute and carrier reagent in the membrane results in the separation of the solute from the feed mixtureCopper Extraction from Ammoniacal Solutions with LIX 84 ,Extraction of copper from ammoniacal solutions with LIX 84 and LIX 54 used alone and their mixture was studied, and a chemical model was proposed and verified The equilibrium extraction constant was correlated with the ionic strength The effect is weak for the strong extractant LIX 84 and its mixture but very strong for the weak extractant LIX 54SOLVENT EXTRACTION AND SEPARATION OF COPPER AND ,(1982) investigated the extraction of copper and zinc by using LIX 34 and Versatic 911 acid and their mixtures and observed that no synergism was found when Versatic acid was added Zinc and copper can also be extracted from sulphate media by carboxylic acids (Preston et al 1985 b)LIX r 84 I E e applicationsbasf agdemetallic cations in a manner similar to that for copper which is described in the following equation 2RH(org) + Cu +2 (aq) R2Cu(org) + 2H + (aq) Copper extraction from typical leach solutions is pH dependent Stripping is accomplished with acid solutions such as a typical barren electrolyte from copper electrowinning TYPICAL PROPERTIESRecovery of Cobalt and Copper From Complex Sulfide ,RECOVERY OF COBALT AND COPPER FROM COMPLEX SULFIDE CONCENTRATES By R O Dannenberg,1 P C Gardner/ S R Crane/ and D C SeideP ABSTRACT The Bureau of Mines conducted laboratory investigations with the objective of developing an alternative process for recovering cobalt and copper from complex sulfide concentrat Processes currently used de­
