Regeneration of sulfuric acid from electrolyte waste of the copper - smelting plant using solvent extraction

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.

Copper Smelting Plant

Variations of stable carbon (13С and 12С) and nitrogen (15N and 14N) isotopic composition are analyzed in forest plants subjected to the emissions of large copper smelting plant. The studies were carried out in pine forests at ten test plots near the Karabash copper smelting plant and in the Ilmen State Reserve at South Urals. The 13С/12С and 15N/14N isotopic ratios were analyzed in leaves of plants of different functional groups (with ecto-, ericoid, or arbuscular mycorrhiza; with nitrogen-fixing symbiosis, and non-mycorrhizal). The 13С/12С ratio did not change under technogenic pollution. The low isotopic 15N/14N ratio was established in ectomycorrhizal trees, while the high ratio was found in herbs with arbuscular mycorrhiza, nitrogenfixing symbiosis, and non-mycorrhizal groups. As compared to nonpolluted habitats, the 15N content in leaves near the copper smelting plant increases by 2.7‰ in the ectomycorrhizal trees and by 3.4‰ in undershrubs with ericoid mycorrhiza, and by 2.2‰ in herbs with arbuscular mycorrhiza. This indicates a significant change in conditions of mineral feeding of plants under heavy metal pollution of natural ecosystems.
