Modeling of hypergene processes proceeding in the tailing dumps of Krasnorechenskaya concentrating mill of Dalnegorsky district in the temperature range of 0 to 45 °C using new thermodynamic data

摘要

The authors have performed the modeling of hypergene processes proceeding in the tailing dumps of the Krasnorechenskaya concentrating mill in the positive temperature range of 0 to 45 °C. New data are obtained on the Eh-pH parameters of equilibrium solutions, quantitative composition of elements in the solution, and possible composition of hypergene and technogenic minerals crystallize in the mining-industrial technogenic system. The modeling is done with maximal, minimal, and average contents of sulfide minerals that characterize the tailings. In the calculations, we use new thermodynamic data for some hypergene minerals taken from the literature sources and obtained by the program founders.
