How to Operate a Flotation Circuit
In short, don't cut the air unless you have to and then do it for as short a time as possible. Add as much air as your machine (froth) REQUIRES. A flotation machine needs deep froth in order to allow time for unwanted mineral to drain from the froth bubbles back into the pulp.
Flotation Circuit
1 Introduction. Flotation circuits are commonly used for the concentration of a broad range of minerals; such circuits also used in wastewater treatment (Rubio et al. 2002 ). Froth flotation is based on the differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/water slurry.

The Bayan Obo mine in China uses magnetic separation and froth flotation to concentrate the REO feed grade from 6 to 65% [11,21, 22]. In general, fatty acids and hydroxamates are the most common ...
SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Traditionally flotation plant design blower selection and control has been based on using an oversized positive displacement blower, or an industrial fan, with any excess air discharged to atmosphere. While easy to select and design, this type of circuit contains inefficiencies especially when it comes to energy consumption. Larger
Froth Flotation Circuit Design And Basic Testwork Requirements
Testwork necessary to define the design parameters for a flotation circuit generally includes: Grindability studies to establish grinding power requirements. Chemical and mineralogical analyses of test composites to establish ore grades, mineral associations and liberation characteristics. Reagent evaluations required for rougher and cleaner ...
Recovering Gold through the Froth Flotation Process
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
