Journal ArticleDOI
Recovery of zinc and manganese, and other metals (Fe, Cu, Ni, Co, Cd, Cr, Na, K) from Zn-MnO2 and Zn-C waste batteries: Hydroxyl and carbonate co-precipitation from solution after reducing acidic leaching with use of oxalic acid
TL;DR: In this article, the authors present the results of reductive acidic leaching of waste material of the zinc-carbon batteries (Zn-C) and zinc-manganese batteries (alkaline Zn-MnO 2 ) delivered by a company dealing with mechanical treatment of this type of waste stream.
Journal ArticleDOI
Enthalpies of phase transition in the lanthanide chlorides LaCl3, CeCl3, PrCl3, NdCl3, GdCl3, DyCl3, ErCl3 and TmCl3
TL;DR: In this paper, the enthalpies of phase transition in the lanthanide chlorides have been measured with a differential scanning calorimeter and also with a Calvet-type microcalorimeter to within an experimental error of ±2%.
Journal ArticleDOI
Heat capacity of LaCl3, CeCl3, PrCl3, NdCl3, GdCl3, DyCl3
TL;DR: In this article, the heat capacities of LaCl3, CeCl3 and DyCl3 were measured by differential scanning calorimetry in the temperature range from 300 K to melting temperatures of the compounds.
Journal ArticleDOI
Calorimetric investigation of NdCl3MCl liquid mixtures (where M is Na, K, Rb, Cs)
TL;DR: In this paper, the molar enthalpies of mixing ΔmixHm in the liquid NaClNdCl3, KCl-Cl-3, RbCl-cl-3 and CsCl-ncl3 binary systems were measured over the whole composition range at 1124, 1065, 1122 and 1122 K, respectively, with an accuracy of about 6%.
Journal ArticleDOI
Incineration and pyrolysis vs. steam gasification of electronic waste.
TL;DR: Three basic, high temperature ways of electronic waste processing, i.e. smelting/incineration, pyrolysis and steam gasification were shortly discussed in the paper, giving a special attention to gasification under steam, illustrated by laboratory experiments.
