The behaviour of enriching silver by extraction chromatography with N263 liquid resin w"as studied. The optimum conditions of the adsorption and elu- tion of silver were examined: The elimination and interference of foreign ions were tested. This method could detect more than O.Ox ppm of silver in ores (sample taken :5g0.
