How a flotation cell works

Dec 14, 2015 Flotation Cell Design and Flotation Flowsheets The “Sub-A” Operates in three zones: in bottom zone, impeller thoroughly mixes and aerates the pulp, the central zone separates the mineral laden particles from the worthless gangue, and in top zone the mineral laden concentrate high in grade, is quickly removed by the paddle of a Denver “Sub-A” Cell

    1 Froth Flotation – Fundamental Principles

    1 Froth Flotation – Fundamental Principles 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. The particles with attached air bubbles are then carried to the surface and

    How Froth Flotation Works

    Aug 08, 2015 Here is a page about the invention of froth flotation as it appeared in a 1917 edition of the Popular Mechanics detailing how it works. Each cell has an impeller, this rotates and acts like a giant mixer. Its purpose is to keep the ore in suspension, provide a passage to allow the air access to mineral, and help distribute the air through the cell

    The process of froth flotation is generally described as a physical-chemical action, where a mineral particle is attracted to, and attaches itself to the surface of a bubble, and is transported to the surface of a cell, where it overflows into a discharge launder, usually with the assistance of paddles, rotating in the direction of the launder (which is typically a trough, whose purpose is to
