TECHNICAL ASSIGNMENT
Regarding: Selection of supplier of reagent for the extraction of copper - LIX 984N
I.
PRODUCTS DESCRIPTION - LIX 984N:
LIX 984N reagent, a 1:1 volume blend of LIX 860N-I and LIX 84N-I, is a mixture of 5nonylsalicylaldoxime and 2-hydroxy-5-nonylacetophenone oxime in a high flash point hydrocarbon
diluent which forms water insoluble complexes with various metallic cations in a manner similar to
that shown below for copper. Because this extractant contains no added modifier it may show
