ABSTRACT:
The present invention relates to a process for cleaning mercury-contaminated soils that is simple, efficient and safe to use. This process can also be used to clean soils contaminated with additional metals, such as zinc, copper and lead, at a lower pH. The invention involves treating contaminated soils with solid hypochlorite in a continuous counter-current process.
