description: The object of research is a sorbent selectively extracting noble metals from cyanide solutions. The subject of the study is the sorption of precious metals (including gold) from solutions in cyanide complexes. The purpose of the work is to study the sorption of gold from cyanide solutions on nanoporous sorbents, namely coconut coals, inorganic sorbents represented by synthetic silicate sorbents with a high specific surface area, obtaining optimal parameters of cyanidation â sorption technology. Research methods â gravimetric method for determining metals in solutions, spectrophotometric method for determining metals in solutions, atomic absorption spectrometry. The results of the study are the isotherms of sorption of gold complexes, the optimal parameters of the process of extraction of precious metals by cyanidation. The scope of application of the results is the extraction of noble metals (in particular gold mining), water treatment and water treatment.
