Aug 01, 2008· The continuous solvent extraction and acid stripping using the mixer-settler were first applied to the nickel recovery from spent electroless nickel plating baths using an organic phase containing 20 vol% LIX84I as the extractant and 2 vol% PC88A as the accelerator
Nickel, Cobalt, and Zinc Recovery by Solvent Extraction The application of solvent extraction to copper recovery can now be considered an established, commercially viable process This position has not yet been reached for the recovery of the other major non-ferrous metals in which we are interested
Nickel laterite ores are becoming an increasingly important source of nickel and cobalt BASF solvent extraction reagents are used in a nickel production plant, Queensland Nickel Inc (QNI), to extract nickel from ammonia solutions LIX® 87QN reagent was developed to fit into a QNI-developed nickel recovery process based on a modified Caron .
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar) There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic
In hydrometallurgy industry production, adapted centrifugal extractor with non-equilibrium extraction to extract cooper, uranium, nickel, cobalt, molybdenum, rare earth metal and other metal elements, using short contact time of the two phases in centrifugal extractor, element with high speed mass transfer was extracted, and the slower was not extracted basically, that realized two elements .
A two-sequential solvent extraction circuits allows nickel and cobalt separation • 94% Ni and 91% Co are totally separated from the feed solution • 20 g L − 1 of cobalt salt solution is effective to remove co-extracted impuriti • The first bench scale solvent extraction flowsheet is ,
Nickel and copper were co-extracted from ammoniacal ammonium sulfate leach liquors (pH-95) with LIX 64N extractant in a laboratory-size mixer-settler continuous circuit Three extraction stages resulted in >99-pct extraction of nickel, substantial copper extraction, and essentially no cobalt extraction ,
Solvent Extraction CYANEX® 272 extractant has proven to be the reagent of choice for the separation of cobalt from nickel from both sulfate and chloride media ,
After producing the nickel matte, further processing is done via the Sherritt-Gordon process First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99% Electrorefining
Solvent extraction as an enabling technology in the nickel industry occasional crud and in some rare cases scale handling) These features contribute to low operating costs and high on-line availability of the typical solvent extraction circuit The first relatively large-scale SX application in
