Solid/liquid Extraction of Zinc-Containing Dusts

Project: Research project

Project Details

Description

Environmentally-friendly waste materials, that can not be eluted, will be more and more important. Especially highly soluble substances like heavy metal chlorides, -sulfates and -oxides have to be conditioned before dumping to fullfill legislative regulations. One of the obvious paths of detoxifying solid waste materials is by means of leaching (solid/liquid-extraction).
In lab-scale extraction experiments the optimal extraction parameters were determined for the leaching of filterdust from steel mills by carboxylic acids.
