Metal extractant RANBAO®NR-20
【Introduction】
Metal extractant RANBAO®NR-20 is a composite of preferred modifiers, surfactants, and anti nitrifying reagents. It can form a water-soluble complex with copper, with stable performance, and is a specialized extractant for anti nitrification. It can be applied to the extraction of copper from acidic leaching solutions, especially suitable for the extraction of copper from leaching solutions containing nitrate ions under high pH conditions.
【Characteristics and Advantages】
(1) Stable performance and excellent anti nitrification effect;
(2) Especially suitable for the extraction of copper from leaching solutions containing nitrate ions under high pH conditions.
(3) It has the advantages of fast extraction kinetics, good phase separation performance, and high Cu/Fe selectivity.
