Lead Zinc 05

Established in 1970, the PbZn symposium series is considered the leading international technical forum for the lead and zinc processing industries. The PbZn 2020 volume addresses all aspects of current processing technologies for primary and secondary lead and zinc, as well as emerging technologies for both metals.

This proceedings volume from the fourth decennial Lead-Zinc symposium brings together plant operators, engineers, and researchers to discuss hydrometallurgical, electrometallurgical and pyrometallurgical aspects of these commercially important metals. Lead-Zinc 2000 will emphasize both the theory and practice of the extractive metallurgy of lead and zinc including benchmark technologies; advances in lead smelting; imperial smelting technologies; commercial and novel leaching processes; solution purification; lead electrorefining; zinc electrowinning; pyrometallurgical refining of lead and zinc; lead and zinc secondaries; process fundamentals and modeling; and new processes and processing concepts. Environmental concerns associated with the processing of both metals will be considered, along with the acceptable disposal of the various slags, residues, and bleed streams produced by the industry. In addition, a select number of overview papers will be included on the economic aspects of lead and zinc, and the new applications for both metals.

Sintering is one of the final stages of ceramics fabrication and is used to increase the strength of the compacted material. In the Sintering of Ceramics section, the fabrication of electronic ceramics and glass-ceramics were presented. Especially dielectric properties were focused on. In other chapters, sintering behaviour of ceramic tiles and nano-alumina were investigated. Apart from oxides, the sintering of non-oxide ceramics was examined. Sintering the metals in a controlled atmosphere furnace aims to bond the particles together metallurgically. In the Sintering of Metals section, two sections dealt with copper containing structures. The sintering of titanium alloys is another topic focused in this section. The chapter on lead and zinc covers the sintering in the field of extractive metallurgy. Finally two more chapter focus on the basics of sintering,i.e viscous flow and spark plasma sintering.
