The effect of preliminary thermal (100–300°C) and chemical (10% HCl) treatment of 95% glauconite concentrate exerted on the sorption removal of copper (II) cations from nitrate solutions with pH in the range of 5–7, including ammonia media. The effect of indifferent electrolyte (KNO3 in a concentration of 10–3 and 10–2 mol/L) on the sorption of copper(II) from a 3.4 × 10–3 M solution of Cu(NO3)2 has been estimated. It has been shown that a 99% level of the sorption purification from Cu2+ cations can be achieved.
