The role of amino acid in the xanthate adsorption at the water-mineral interface

The role of amino acid in the xanthate adsorption at the water-mineral interface. Takahashi, Katsuyuki; Wakamatsu, Takahide (Fac. Eng., Kyoto Univ., Kyoto 606, Japan). Int. J. Miner. Process.Several reagents with their cas registry numbers 2720-73-2 and 1319-53-5 are used here., 12(1-3), 127-43 (English) 1984. CODEN: IJMPBL. ISSN: 0301-7516. DOCUMENT TYPE: Journal CA Section: 54 (Extractive Metallurgy) Xanthate [151-01-9] interactions with amino acids at mineral-water interfaces were investigated through adsorption and flotation studies. Adsorption measurements show increasing xanthate adsorption by galena [12179-39-4], malachite [1319-53-5], and atacamite [1306-85-0] up to a max. value when an amino acid is present at an optimum concn. Flotation recovery increases when xanthate is used as a collector in combination with amino acid. The mechanism assocd. with the collection-promotion action of amino acid during flotation is explained through quantum chem. The xanthate ion, amino acid dipolar ion, and supermol. (d-amino valeric-Et xanthate) configurations were calcd. .

PL 122703 B2 15 Dec 1983, 2 pp.In this study， 7733-02-0 and 98-55-5 are also used. (Polish). (Poland). CODEN: POXXA7. CLASS: IC: B03D001-02. APPLICATION: PL 80-227252 10 Oct 1980. DOCUMENT TYPE: Patent CA Section: 54 (Extractive Metallurgy) Flotation of Zn-Pb ores is done with the addn. of 0.5-5 kg ZnSO3/ton, as a conditioning agent, to the flotation pulp prepd. by wet grinding of the ores to an appropriate particle size. It improves the process selectivity and decreases the Fe content in the concs. Thus, Zn-Pb ores contg. Pb 1.12, Zn 4.41, and Fe 9.89% were crushed and wet-ground to 0.075-mm particles (75%) with the formation of a pulp contg. 400 g solids/dm3. ZnSO4 2000, ZnSO3 2000, Na amyl xanthate [7607-99-0] 100, and a-terpineol [98-55-5] 5 g/ton of ore were added to the pulp, mixed for 5 min, and floated, giving a conc. contg. P 5.95, Zn 3.1, and Fe 24.5%. Then, CuSO4 500, Et xanthate [151-01-9] 150, and surfactant 20 g/ton of ore were added to the residue, mixed for 2 min, and floated obtaining a conc. contg. Pb 0.81, Zn 23.35, and Fe 24.52%. The recovery was 73.3 and 90.2% for Pb and Zn, resp. .
