The disposal of sulfide-arsenic cake
Autor: D. O. Novikov, L. I. Galkova, G. I. Maltsev
Publikováno v: Izvestiya. Non-Ferrous Metallurgy. 1:16-25
When processing sulfide copper-zinc concentrates at copper smelters, sulfide-arsenic cakes are formed, which are subject to disposal. To solve the global environmental problem of arsenic in the metallurgical and mining industries, it must be reliably

Phase Equilibria for a Zn–Ag Alloy during Vacuum Distillation
Autor: A. A. Korolev, G. I. Maltsev, Konstantin L. Timofeev
Publikováno v: Russian Metallurgy (Metally). 2021:978-986
When impurities are removed from crude lead by metallic zinc, a silver foam (SF) containing lead, zinc, and silver forms on the melt surface along. Vacuum distillation can be used to separate the SF components, since it is one of the most environment
