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
advantages when used for copper extraction from solutions containing soluble silica or finely divided
solids.
