Abstract

The use of mineral processing techniques to remediate shooting range soils contaminated by leadcontaining shotgun pellets has bow been evaluated. Most of the lead in the soil sample is in the form of coarser pellets, which can be easily recovered mechanically by combining screening with a consecutive concentration stage. The total recovery of lead into practically pure pellet product in 90% in this process. The fine, altered part of the lead pellets, identified as a carbonaceous phase, is much more problematic. As this phase is more soluble and has a large specific surface areas, it forms a particularly hazardous source of contamination for the environment for the environment. Complex-forming leaching and a cosecutive precipitation by sulfide was used to recover the lead from this finer part with a recovery of about 96%. A total load recovery of 99.9% can be reached by combinig the mechanical and leaching processes.
