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.
