RECOVERY OF COPPER FROM SOLUTIONS WITH SUPERFINE MODIFIED ALUMINOSILICATES
https://doi.org/10.17073/0021-3438-2016-1-4-9
Abstract
The study covers the sorption of copper ions from standardized test solutions (1–100 mg/dm3 Cu) at pH = 5,5÷9,5 and waste waters (composition, mg/dm3 : 0,2–0,4 Cu; 0,2–0,3 Zn; 0,3–0,4 Ni; 0,3–0,5 Fe; 0,6–0,9 Pb; 1,8 As; 0,2 Mn; 3,2 Mg) at pH = 8,5 on a modified Na-montmorillonite from the Zyryanovskoe field in comparison to the liming method. Significant sorption capacity of superfine aluminosilicates (~3,0 mg-eq/g) allows to obtain sediment rich in heavy non-ferrous metal ions suitable for further recuperation of metals from sediment and purified water with residual concentrations of metals (Cu < 0,01 mg/dm3 ) compliant to emission standards.
