how froth flotation works - 911 metallurgist,how froth flotation works. to start with i will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. when the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids..froth flotation - wikipedia,froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. this is used in mineral processing, paper recycling and waste-water treatment industries. historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. it has been described as 'the single most important operation used for the recovery and upgrading of sulfide ores'. the development of froth flotation.

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
184.108.40.206.2.2.1 froth flotation. the froth flotation process is more than a century old and was developed over a long period of time . it takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float, allowing for a separation between

froth that does form on top of the clarifier can be eliminated by employing a floating boom that is placed directly in the thickener (fig. 11.24b) and used in conjunction with water sprays. the floating boom can be constructed out of inexpensive pvc piping, and is typically attached to the rotating rakes.

principle of operation froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral.
a frother is applied to create the bubbles in the right size which will collect the valuable mineral. the hydrophobic particles then attach to the bubbles and raise to the top of the tank, while the hydrophilic particles mix with the water and drop to the bottom of the flotation tank.

describe froth flowcion. nevercheless it is importanc to understand that flotation evolved through three principal stages of development. these stages will be discussed in more detail later. the process of flota tion involves: 1. reduction (crushing) of the ore to a size that will free the targeted minerals; 2.
based on the mass balance of air passing through the froth phase, a mathematical model of froth transportation is developed for a cylindrical flotation cell. the model describes froth transportation time from the point of entry at the pulp-froth interface to the concentrate launder as a function of the geometrical dimensions of the flotation cell, the concentrate launder and froth crowder designs, as
