Soils from an abandoned pb battery processing facility were characterized prior to the selection of the extraction technique. Reflected light microscopy and electron beam methods were used to locate pb-bearing phases and to quantify the compositions of the phases. It was found that soils are composed primarily of quartz and feldspars with minor amounts of iron and titanium oxides. Lead is primarily present as an oxide or sulfate that is associated with the silicate minerals. Specific phases identified were pbo; pbo2; cerrusite, pbco3,; anglesite, pbso4; galena, pbs; and magnetoplumbite, 2pbo.3Fe2o3; or plumboferrite, pbo.2Fe2o3.
