The paper deals with the synthesis and characterization of some of the quinoline derivatives with chelating functional groups (with N-N and N-Cl donor atoms) as collector for concentration of low grade ores by froth flotation. Syntheses of substituted homophthalic acids (O-O donor atoms) are also reported.


Key words

Flotation reagents, Synthesis, Quinolines, Homophthalic acids, Microflotation.
