AbstractGalena is the principal ore mineral for lead industry and the production of lead and its alloys. The industrial processing of galena includes its oxidized roasting to lead oxide, followed by reduction smelting of lead oxide agglomerate with coke in the blast furnace to commercial lead.The present work reports a thermal analysis study of oxidized roasting of Egyptian galena using a derivatograph. The reaction products were identified microscopically and by using a Siemens Crystalloflex…
