“…In the authors' previous works [2,3] such investigations were carried out for the thermodynamic system with 40 hypergene and technogene minerals. Later, in the literature the thermodynamic parameters were found for pyrargyrite, hisingerite, and hydrogoethite and were calculated (A.A. Tupitsin and V.A.…”

Modeling allowed us to show Eh-pH parameters of the technogenic mineral formation in the mining-industrial technogenic system of polymetallic ores of Dal’negorsk district, to study the process of the hypergene mineral crystallization from solutions, to consider the qualitative and quantitative ionic composition of solutions, to show the role of hypergenesis in the contamination of surface and ground waters of the area. The aim of this work is to estimate the action of the CCM tailing oxidation on the hydrosphere of the district using the method of physicochemical modeling. The results obtained testify to a significant evacuation of a wide range of elements of sulfide ores (Zn, Pb, Cu, As, S) and enclosing rocks (Si, Al, Mg, Ca, K, Na) from the CCM tailing dumps into the surface waters polluting the hydrosphere with them.

В статье обсуждаются результаты моделирования физико-химических параметров кристаллизации гипергенных минералов из рудничных, шламовых и дренажных вод в горнопромышленных техногенных системах сульфидсодержащих месторождений Дальнегорского района. Моделирование выполнено с помощью программного комплекса «Селектор». Рассчитаны Eh и pH параметры и определены температурные условия выпадения гипергенных минералов из растворов, выделены минеральные ассоциации. Показано, что гипергенные и техногенные минералы кристаллизуются в широком интервале температур (от -25 до +45 °С) при значительных вариациях значений Eh (от 0.6 до 1.2 В) и pH (0.3-13.7). Главную роль при формировании минеральных парагенезисов играет состав руд и вмещающих оруденение пород. Чем выше содержание сульфидов в хвостах обогащения, тем более кислые растворы они продуцируют, тем больше вторичных минералов образуется.Ключевые слова: гипергенные и техногенные минералы, хвосты обогащения, физико-химическое моделирование, рудничные, шламовые и дренажные воды.The paper displays results of modeling the physical-chemical parameters of crystallization for hypergene minerals in mine, slurry and drainage waters within mining technogene systems of sulfide-bearing ore deposits of the Dalnegorsk district. The modeling has been carried out with the software package «Selector». Eh and pH parameters were calculated, thermal conditions of the saturation of hypergenic minerals from solutions were determined, and mineral assemblages have been distinguished. It is shown that hypergenic and technogenic minerals crystallize in the wide range of temperatures (from -25º to +40ºC) with significant variations of Eh (from 0.6 to 1.2 V) and pH (0.3-13.7) values. The principal role in the formation of mineral parageneses belongs to the composition of ores and host rocks. The greater is grade of sulfides in tails of processing, the more acid solutions they are producing, and the greater is the number of newly formed secondary minerals.
