Abstract

The article presents modeling results of drainage
water in the tailing dumps of the deposits of Komsomolsky tin ore district in the temperature range
from -10 to +45 C. The authors researched Eh-pH
parameters of technogenic mineral systems for
different ratios host rock - sulfides (95:5, 90:10,
80:20 and 60:40) in the tailings. The process of
crystallization of hypergene minerals from micropore solutions was considered, their qualitative
and quantitative composition was determined, their
impact on the surface and ground water of the area
was shown.
