ABSTRACT:
A process for treating particulate material containing heavy metal generated during a manufacturing process is disclosed. The process includes providing particulate material containing heavy metal within an enclosed area and mixing an additive of calcium silicate forming material with the particulate material in the enclosed area to create an additive-particulate material. The additive-particulate material can be passed into a waste collection device located downstream of the enclosed area. The calcium silicate forming material can be provided as particles with a particle size of minus 50 to plus 325 mesh. An additional aspect of the invention is an additive for use in such a process for treating metallic oxide impregnated dust, which has a particle size of plus 325 mesh and consists essentially of calcium silicate forming material.
