Abstract
Samples of up-draft sinters produced at three different Missouri lead smelters were studied, to determine the chemical phases present, as a first step toward a more complete understanding of the lead blast furnace operation. The sinters seemed to be basically similar, and all the results reported are from samples from one smelter (Herculaneum smelter, St. Joe Minerals). Analytical tools used included the electron microprobe and scanning electron microscope with a non-dispersive X-ray spectrometer attachment Major phase that were positively identified are metallic lead, lead sulfide and zinc ferrite. The predominant lead phase was tentatively identified as a lead oxide-silicate compound. Other compounds probably present are calcium, iron, zinc-silicates or some combination of calcium, iron or zinc with silica. Contrary to the results of other investigators no lead oxide or basic lead sulfate compounds were identified. It appears that the majority of the lead is present in the sinter as a lead oxide-silicate phase. © 1974 American Society for Metals, The Melallurgical Society of AIME.
