Extended ICP-OES and AAS analysis of floated polysulphide concentrate from the Asgat polymetallic ore revealed that contains 0.91% silver, 18.2% copper, 19.4% antimony, 2.03% arsenic 1.6% bismuth together with other elements. The prevailing minerals in are tetrahedrite, bismuthinite, chalcopyrite, arsenopyrite pyrite non-ore i.e. siderite, muscovite quartz. content above was estimated by X-ray ...

Spherical pellets of antimony sulphide were dissolved in 1 molar sodium hydroxide solutions at different temperatures. It was found that the shrinking core with ash layer model could satisfactorily explain the dissolution process. Using this model it was found that initially the rate controlling step is a chemical reaction with activation energy of 10.2 kJ/mol. As the ash layer builds up, diffu...

BACKGROUND To study the value of periareolar intra-dermal injection of Tc-99m sestamibi (MIBI) for sentinel node mapping in breast carcinoma. MATERIAL AND METHODS Fifty patients with early-stage breast cancer were included in our study. 17.5 MBq Tc-99m-MIBI was injected intradermally to 25 patients and the remainders were injected with the same dose of Tc-99m-antimony sulphide colloid. Anteri...

In this study, density functional theory is used to evaluate the electronic structure of the antimony chalcogenide series. Analysis of the electronic density of states and charge density shows that asymmetric density, or ‘lone pairs’, form on the Sb cations in the distorted oxide, sulphide and selenide materials. The asymmetric density progressively weakens down the series, due to the increase ...

Rrown up girls and women. It is supposed to act ay a tonic to the nerves of the eyes and to strengthen the sight. In books on indigenous drugs in English, it is described both as trisulphide of antimony and lead sulphide (galena) (Ainslie, 1813; Chopra, 1933; Dey. 1896; Nadkarni, 1927; ahd Watt, 1889). In connection with the investigations on lead content of normal human tissues, excreta and ha...
