PL 126059 B2 30 Jun 1984, 2 pp. (Polish). (Poland). CODEN: POXXA7. CLASS: IC: B03D001-00. APPLICATION: PL 81-232915 3 Sep 1981. DOCUMENT TYPE: Patent CA Section: 54 (Extractive Metallurgy) The yields and Cu content of Cu ore concs. were increased when flotation agents contg. lignin (I) [9005-53-2] (byproduct of vanillin prodn.) was used. Thus, a 70.32% yield of a conc. contg. 12.17% Cu was obtained from a high-clay slurry contg. 0.661% Cu by flotation with Na ethylxanthate [140-90-9] 250, diacetone alc. [123-42-2] 260, mesitylene oxide [38440-96-9] 260, and I 196 g/ton (dry ore basis).

System for adsorption of carbon disulfide vapors

System for adsorption of carbon disulfide vapors. Konieczynski, Jan; Konaszynska, Zofia (Pol.). Ochr. Powietrza, 17(6), 153-7 (Polish) 1983. CODEN: OCPOAF. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 45, 54 The synthesis of EtOCS2Na (I) [140-90-9] for Cu ore flotation is assocd. with the emissions of I dust and CS2. A 2-stage waste gas purifn. system, designed to remove these pollutants, consisted of a foam scrubber and a charcoal absorber. The removal of I dust was complete and the removal of CS2 (av. concn. in waste gas 7 g/m3) was 93.82-97.20%.
