    The depressing effect of NaAl on the flotation of Ca 2+-activated quartz particles were thoroughly investigated, in a fatty acid flotation system. In order to reveal the possible inhibitory mechanism of NaAl in Ca 2+ -activated quartz flotation, interactions between NaAl and sodium oleate (NaOl) were analyzed at both liquid/liquid and solid ...

    Give the name and role of collector and froth stabilizer

    Aug 17, 2018 In froth flotation process, the role of collector (Pine oil, Sodium ethyl xanthate) is it attracts the ore particle on the surface of the froth. This mechanism takes place by surface adsorption. In froth flotation process, the role of froth stabilizer (Aniline, Cresol) is it stabilizes the froth.

    Jan 02, 2012 The adsorption of fatty acids on hematite plays a key role in the direct flotation route. In the literature, it is generally accepted that fatty acids adsorb on the surfaces of hematite through chemical bonding. Based on infrared studies, Peck et al.[6] established that oleic acid/sodium oleate chemisorb on hematite.

    Roles of Surfactants in Flotation Deinking

    One of the most commonly used surfactants in the flotation deinking process is fatty acid soaps. Generally, fatty acids react with calcium ions in the system to form calcium soaps which can adsorb onto the ink surface and provide the collector action (9). The fatty acid soap system is not a good dispersant in general. It can function as a dispersant

    Frothers an overview ScienceDirect Topics

    Froth stability is critical for ink removal. Ink removal efficiency increases with an increase in froth stability. A fatty acid system could serve not only as the collector but also as the frother and dispersant in a flotation deinking operation only when there are free fatty acids in the pulp suspension.

    In froth floatation method collectors such as pine oil

    Froth floatation method is used for removing gangue from sulphide ores. In this process, a suspension of the powdered ore is made with water. Collectors and froth stabilisers are added to it. Collectors (e.g., pine oils, fatty acids, xanthates, etc.) enhance nonwettability of the mineral particles and froth stabilisers (e.g., cresols, aniline) stabilise the froth.
