in the alloy contained metallic Pb, metallic Sb and a small amount of Cu2Sb and FeSb2 intermetallic compounds. The slag was mainly composed of kirschsteinite and fayalite. Zinc in the raw material was mainly oxidized into the slag phase in the form of zinc oxide. Key words: jamesonite concentrate; metallurgical process intensification; slag type; pyrometallurgy; oxygen-enriched direct smelting 1......
