【 摘 要 】

The article presents the results of technogenic waters composition physicochemical modeling for Kavalerovsky and Dalnegorsk ore districts closed tailing dams (Primorsky Krai, South of the Russian Far East). Thermodynamic modeling in "Selektor" software package in a wide temperature range from -10 to +30 C allowed to establish the Eh-pH characteristics and to study quantitative and qualitative composition of slurry and drainage waters.
