Petrographic study of a sinter from secondary lead raw material

Petrographic study of a sinter from secondary lead raw material. Tarasenko, M. M.; Murav'ev, V. N.; Guriev, A. E. (Sev.-Kavk. Gorno-Metall. Inst., Ordzhonikidze, USSR). Izv. Vyssh. Uchebn. Zaved., Tsvetn. Metall., (4), 54-6 (Russian) 1977. CODEN: IVUTAK. DOCUMENT TYPE: Journal CA Section: 54 (Extractive Metallurgy) The mineral structure was studied in agglomerates of secondary Pb raw materials. Magnetite [1309-38-2], hematite [1317-60-8], metallic Pb, complex spinels, 2CaO.PbO.3SiO2 [18839-68-4], 3PbO.3SiO2 [10099-76-0], and PbO.Fe2O3 [12186-59-3] were identified in the sintered briquets. The silicate binding matrix of the agglomerates was mainly wollastonite [13983-17-0].

Study of the reduction of lead silicate glasses by complex reducing agent (carbon monoxide + solid carbon)

Study of the reduction of lead silicate glasses by complex reducing agent (carbon monoxide + solid carbon). Polyvyannyi, I. R.; Safonova, N. N. (Inst. Metall. Obogashch., Alma-Ata, USSR). Deposited Doc., VINITI 375-76, 16 pp. Avail. VINITI (Russian) 1976. DOCUMENT TYPE: Report CA Section: 54 (Extractive Metallurgy) The redn. kinetics was studied for Pb silicate glasses at 600-800° with a combined reducing agent of CO and graphite to simulate the conditions of Pb smelting in a shaft furnace. Expts. were performed with 2PbO.SiO2 (I) [13566-17-1] and PbO.SiO2 (II) [10099-76-0] in graphite crucibles in a CO flow of 6 L/h. The overall redn. degree (x) was 70.5 and 66.4% for I and II, resp. at 700° after 10 min redn. time (t). A linear function log (1/1-x) vs. t corresponding to a 1st-order reaction was established for the initial redn. period (1-5 min). The redn. activation energies at 600-700° and x = 20% were 78.5 and 123 kJ/mol for I and II, resp.
