Sulfide-bearing mill wastes of the Salair Ore Processing Plant situated in the Kemerovo region (Russia) were investigated in the time period 1999-2011. Multipurpose studies of the Talmovskie mining tailings allowed the determination of the composition of the wastes, the acid mine drainages, and the affected groundwater.

Interest in the redistribution of As-bearing species during long-term storage of hydrometallurgical tailings is motivated partly by the need to prevent As from being released into the environment. The speciation of As in mine wastes from the Tuva Cobalt Plant (Khovu-Aksy mine site, Tuva Republic, Russia) has been studied using mineralogical techniq...

This study presents data on the geochemical composition of boiling mud pools at the Mutnovsky volcano. The physicochemical characteristics of the pools and the concentrations of major, minor and trace elements in pool solutions vary widely. A comparison of the geochemical compositions of host rocks and solutions indicates that leaching from rocks i...

The paper presents the results of numerical simulation of a subaerial volcanic hydrothermal system. The model is based on the factual data on the rock composition and the geological structure of the Mutnovsky Volcano. We develop a new approach to construct the numerical model of a volcanic hydrothermal system. According to this approach, at each st...

ABSTRACT: Authors of papers to proceedings have to type these in a form suitable for direct photographic reproduction by the publisher. In order to ensure uniform style throughout the volume, all the papers have to be prepared strictly according to the instructions set below. A laser printer should be used to print the text. The publisher will redu...

The distribution of chemical elements (Zn, Cu, Fe, Pb, Cd, As, Sb, Be) in the water and bottom sediments of the Belovo swamp-settler was investigated in our integrated study of geochemistry, geophysics, and hydrobiology. This swamp collects drainage escaping from clinker heaps made up of waste of pyrometallurgical smelting of sphalerite concentrate...

This study deals with the genesis of contrasting thermal water types from active volcanoes. The objects of our study are volcanic springs from the Kamchatka and Kuril islands (Russia). The results of hydrochemistry, geophysical study and physicochemical modeling show that contrasting types of thermal waters can be originated from a single magmatoge...

This paper reports results from a hydrogeochemical study of thermal springs on Mutnovskii Volcano. The solutions of boiling pots and the pore water of thermal localities in the Donnoe Field were found to have an anomalous composition over a wide range of chemical elements, including rare earth elements (REE) and platinum-group elements (PGEs). The...

A mathematical model is proposed to describe the dynamics of phase fronts in volcanogenic orthomagmatic fluid systems (VOFS). It has been shown that these systems require rather short geologic times to reach a quasi-stationary state. This process is accompanied by slow cooling and pressure decrease as the bubbling front within the intrusive body su...

High sulfide tailing of copper ores deposited within the line of Karabash (South Ural) is a constant source of toxic elements, releasing in surface water, soil, bottom sediments owing to intensive tailings oxidation and dissolution. To understand features of toxicant migration vertical distribution of elements (Cu, Zn, Pb, Cd, As, Se, Te and others...

On the basis of numerical experiment results an appraisal is given for 1D approximation of development peculiarities of above-critical state of water magmatic fluid in petrophysically nonhomogeneous near-surface sections of andesite volcanoes. The known data on Ebeko volcano thermal systems were used as a real sample for the model construction. It...

The study of inactive As-bearing tailings impoundments at the Khovu-Aksy mine-site (Russia) revealed high concentrations of As in the porewater of tailings solids and in their aqueous extracts, as well as in adjacent soils. In these investigations, experimental leaching of As-containing tailings was performed in the laboratory. The three types of s...

Results of a field experiment demonstrating the response of a reservoir (Ob reservoir) to the inflow of a restricted portion of an acid mine drainage solution (AMD) derived from the Berikul sulfide tailings is presented. Drainage water samples from Berikul tailings are acidic (pH 2.0–2.4), with high levels of Fe (up to 30 mg/l), As (up to 4.5 mg/l)...

Evolution of fluids in igneous and hydrothermal activity is a key point in understanding magmatic processes. Overview papers on melt inclusions and quench glasses (1, 2) contain a collection of 5000 reliable analyses of volatiles. A large database has been obtained on high-temperature (>700°C) hydrothermal systems (3) in which gas composition appro...
