Effect of galena contained in dust from Zn–Pb metallurgical processes on environment

This paper assesses the effect of galena emitted with dust from an electrostatic precipitator at Miasteczko Śląskie Zinc Smelting Plant (Poland) onto a soil and water environment. The Eh–pH diagrams plotted in the temperature range of − 3 to 25 °C serve to determine the conditions of PbS stability and conditions under which its decomposition may occur, resulting in the release of ionic forms of lead into the soil and water environment. Determination of the mobility of galena emitted with metallurgical dust is a current and important issue in view of the geochemistry of mineral components in the environment.

The article considers that the course of more than 5 decades as a result of the infiltration of contaminated waters of open pits, dumps, slag accumulators of the copper smelting plant (CSP), the production association (PА) "Ammophos", tailing dumps of copper concentrating factories (СCF -1 and СCF -2), as well as due to the leakage of reagents from the sulfuric acid shop through rocks that are not consistent in area and insignificant thickness of loess-like loams, and the penetration of polluting components into the aquifer occurs. Due to the action of the infiltration flow, a change in the chemical composition of soils occurs on solid soil particles, a number of chemical compounds are sorbed. The article provides recommendations for reducing the pollution of the geological environment.
