  • OUTOTEC FLOTATION TECHNOLOGIES

    • You are processing ore from a smaller deposit in a remote location • You need to replace old, poorly performing flotation cells • You require temporary production capacity during a brownfield modernization project in order to minimize production losses The Outotec cPlant is a low-capacity flotation plant

  • Improved Flotation Separation of Rare Earth Ore | SBIR.gov

    A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

  • Production of High Grade Iron Ore Concentrates Using Flota.

    • Incorporate flotation into a plant presently using other concentration methods to permit the production of low silica pellets. • Increase the flotation capacity of an existing plant. • Improve the overall plant iron recovery by re -treatment of the tailings. • Install a circuit capable of producing more than one produ ct .

  • Froth flotation | ore dressing | Britannica

    Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

    Flotation. Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore.

    Description. The process of the present invention accelerates the flotation kinetics for sulfide ore resulting in increases in average from 6% to 9% of total copper recovery and 2% of copper grade. For some ores molybdenum and iron recoveries and grades are also increased.

  • Flotation Research of a Fluorite Ore

    Abstract: Depressants used in flotation can inhibit floatable gangue minerals to improve concentrate grade. In this paper, four different commonly used depressants were adopted in order to investigate the effect of depressants on chalcopyrite index and to investigate their inhibition effects on chalcopyrite flotation.The experimental results indicate that, in the flotation system of natural pH ...
