lyyionic collectors for iron ore flotation

    Reagents in iron ores flotation - ScienceDirect

    2005-2-1  3. Cationic collectors. Primary fatty amines, utilised in the pioneer USBM process, are no longer employed in the flotation of iron ores. They were modified with the insertion of the polar group (O–CH 2) 3 between the radical R and the polar head NH 2 of the primary amine. Due to the presence of the covalent bond C–O, characteristic of the organic function ether, reagents belonging to this ...

    CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION

    2020-5-6  The collector is the most important reagent used in the iron ore flotation process. The function of the collector reagent is to promote affinity between mineral particles and air bubbles by formation of a water-repellent coating on the surface of the mineral particle. Most collectors in current use are heteropolar; i.e., they contain both a polar

    Investigation of Adsorption Mechanism of Reagents ...

    2018-7-1  Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates, fatty acids and hydroxamates. Direct flotation route was incorporated in the industries in the 1950s in Humboldt Mine, USA (1954), Republic mines USA (1956), Groveland mine USA and Anshan Iron and Steel corporation ...

    Utilization of novel ester-containing quaternary

    2013-1-15  The flotation of quartz, silicates, and mica is frequently carried out with cationic collectors. Reverse cationic flotation of quartz is very effective for the beneficiation of iron ores to produce high grade iron ore concentrates. In this process, quartz as a main gangue mineral is floated with cationic collectors.

    Role of silica and alumina content in the flotation of ...

    2016-3-10  Flotation studies of naturally occurring iron ores further established the fact that it is easier to upgrade the iron values from a high silica ore compared to a high alumina ore. It was possible to produce an overall iron concentrate containing 62% Fe with 86% recovery for a silica bearing ore, but the grade and recovery of an alumina bearing ...
