This is a mobile process to remediate heavy metal-contaminated small arms firing range soil. The soil is treated on-site and produces clean soil and metal byproducts for recycle. Mineral beneficiation apparatuses (mineral jigs, spirals, screens, etc.) are used to remove about 90% to 95% of the metal from the sol id as fragments. Impact of high velocity bullets smear lead on the soil grains and fragments into the micron sizes. This lead is removed with a dilute acetic acid solution about half the strength of household vinegar. This technology can be applied to base closures, abandoned sites, and maintenance of active sites.
