The lead–zinc tailings induce acid mine drainage and heavy metals pollution. • The sulfur in the lead–zinc tailings can be removed during roasting. • The SO 2 in the flue satisfies the requirement of producing sulfuric acid. • The cinder is nonacid forming and can be processed for further recovery.

Mine Tailing Transfer. Mineral tailing ponds generate significant amounts of hazardous solid and liquid mine waste such as: heavy metals, metalloids, radioactive waste, acidic water, and process chemicals. These wastes (tailings) accumulate at the bottom of containment ponds, causing several environmental hazards and reduced water volume.
