“…Mikroflotacijska ispitivanja su rađena u aparaturi sa Halimondovom ćelijom. Originalna Halimondova ćelija [26], kao i njene brojne modifikacije [27][28][29][30][31] često se koriste za ispitivanje flotabilnosti minerala. Flotacija u Halimondovoj ćeliji obično je praćena i drugim procesima, uključujući agregaciju čestica kao i mehanički prenos finih čestica.…”

The aim of this work was to study floatability of the mineral sheelite from mine 'Rudnik', central Serbia. Flotation tests of the mineral in a Hallimond tube cell were carried out in four different types of water, namely: tap water, distilled water, rain water and spring water. All types of water had different hardness and conductivity as well as natural pH values. It was found that the flotability of mineral scheelite depends on the hardness and electro-conductivity of the chosen type of water as well as on Ca2+ content. Also, it was found the floatability of mineral depends on the scheelite particle size fraction used in microflotation experiments. Presented results may be useful for proper selection of type of water, as well of the type of reagents used in flotation processes

The adsorption of laurate and myristate ions on quartz from solutions containing (1 to 25) × 10−5 gm. ions/liter of adsorbate at different pH values, both in the absence and in the presence of Ca++ ions, has been measured using C14‐labelled compounds as tracers. The results have been correlated with the flotation behavior of quartz as determined by Hallimond tube and bubble pick up techniques.

The mechanism of the adsorption of alkyl xanthate species on galena

Oxidation of galena produced thiosulphate and sulphate ions at the mineral surface but flotation activity, using isopropyl xanthate as collector, was found to depend on the concentration of thiosulphate ions at the surface. It is proposed that the thiosulphate ion reacts with di‐isopropyl dixanthogen formed by oxidation of xanthate ion in solution. It was demonstrated that these species react in homogeneous solution to give xanthate and xanthogen‐thiosulphate ions. The proposed surface reaction may account for the formation of a layer of adsorbed xanthate ions and for the surface redox potential being raised to a value where more xanthate ions can be chemisorbed and where dixanthogen is stable.
