CO2-Uptake Enhances Chromate Release from Fresh Chromium Ore Processing Residues (COPR)

Topic:

Soil and groundwater contamination and remediation

Chromium ore processing residue (COPR) still contains considerable chromate which can lead to groundwater contamination at uncontrolled dumpsites. The alkaline pH and presence of portlandite introduced in the high-lime roasting render COPR a potential CO2-trap. To assess whether this feeds back on...Read more
