Processes in passive mine water remediation with zero-valent iron and lignite as reactive materials

Abstract

For in-situ decontamination of mine water a reactive material was developed by Wismut GmbH and Deutsche Montan Technologie GmbH. In different scaled tests mixts. of iron chips and lignite proved most effective in terms of all contaminants examd. (heavy metals, radionuclides and nitroaroms.). Studies showed different pattern of contaminant accumulation depending on the dominant fixation processes.
