Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes are depleted and replaced by ore bodies th
Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes are depleted and replaced by ore bodies that were formerly considered too difficult. In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not wanted. As an example, sodium ethyl xanthate may be added as a collector in the selective flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. The froth is removed from the cell, producing a concentrate ("con") of the target mineral. Frothing agents, known as frothers, may be introduced to the pulp to promote the formation of

Flotation is both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of the flotation machine, as well as a host of other factors which affect the flotation of each specific ore must be combined to

Provision to remove froth by the use of froth paddles on all flotation cells should be included in the original design. The additional capital cost required for froth paddles is a reasonable investment since these devices tend to negate errors in flotation pulp level or frother addition.

The basic factors, principles and variables affecting froth flotation are enumerated in condensed form below:. Ore. (a) Mineralogical character. (b) Fineness of grinding. (c) Method of grinding. Agents. (a) Principal flotation agent. (“Oil”) α Character.

Aug 23, 2016· Traditionally, flotation plant operators have had to depend on visual assessments of froth appearance when making operative decisions. The FrothSense system measures several essential

mercially installed in 1906 in the Adelaide Mill at Golconda, Nevada. In 1911, the Morning Mine near Mullen, Idaho used the process on lead-zinc ores in its mill. Because the process was extremely fragile, its use was short-lived. The Idaho mill closed by 1920.14 Froth Flotation The first successful commercial mill using froth


Froth flotation grinding mills froth flotation cells the process of froth flotation entails crushing and grinding the ore to a fine size this fine grinding separates the individual mineral particles from the waste rock and other the figure above is a simplified flow sheet showing the basic steps involved in 1 froth flotation fundamental.

Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up

Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh. In most cases the potash is floated in the froth product and the salt, NaCl, discarded as tailings.

The development of large scale stirred mills like the IsaMill has now enabled simple circuits with excellent fines recovery. The ability to grind in a small footprint with high energy efficiency and sharp size distribution supports a staged grinding and flotation approach, applying grinding power only where liberation is needed.
