Gas Flotation I • Three basic Variants on the Technology –Mechanical Flotation (e.g., conventional Wemco) –Hydraulic Flotation • (a.k.a. Induced Static Flotation) –Dissolved Gas Flotation • Captures oil and oily-solids (inorganic TSS) • Up to 80% of flotation takes place in the first cell • Balanced skimming is critical for efficient flotation

Flotation cells have three main control parameters. (1) reagent dosing rate (2) froth depth and (3) air addition. rate. Many other parameters may vary such as feed rate, particle. size distribution and head grade, however these are the output. of upstream processes and are not controlled in the flotation. circuit itself.

A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell.

Design of flotation cells has been improved and simplified to handle increased tonnage. One such development was the "free-flow" tank design. Another change has been the use of flotation mechanisms which can be removed from the flotation machine quickly for the inspection or change of wearing parts. A simple change in the …

Froth flotation is a mineral processing technique that is popular when processing low-grade ores. It involves introducing chemically treated, finely ground ore in the form of a slurry into a flotation cell where the air is also added in the form of bubbles. The cell is agitated resulting in the air bubbles rising to the top and creating a froth, as …

Flotation Cell Requirements. Regardless of which type of flotation cell is used to achieve mineral or coal flotation, a machine has two main requirements: 1. Suspension. 2. Aeration. In suspension, it is essential that the impeller or air jet of the machine is capable of keeping the solids in the pulp in suspension.

In flotation process, the efficiency and selectivity depend on mineralogy, particle size distribution and liberation, reagents added, mixing, and particle coverage. However, the kinetics of particle recovery is highly dependent on cell hydrodynamic and circuit configuration and operational strategy. Controlling froth depth and gas flow rate, …

Froth Floatation 1.2 Classification of Flotation cells 1.2.1 Vacuum Flotation A vacuum flotation is a method of separating solids by floating the solids on the surface of the liquid instead of air. This technique is seen used in paper industry for the de-inking or recycling of pulp before it is to be disposed to the waste streams to achieve maximum recovery.
