The third flotation test performed. by coal laboratories is known as Ultimate Froth Flotation and is performed in a large sump (Fig. 10.17) filled with 12 L of water and up to 1200 g of dry solids. During this test the coal slurry, with a particle size less than 0.500 wedge wire (w/w), is continuously recirculated by a pump from the mixing sump ...

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

We can certainly attest to the capacity of the HydroFloat cell to float coarse sulphides up to around 2 mm. We used a lab-scale HydroFloat cell in two PhD projects in our long-running AMIRA P260 flotation project. The low turbulence conditions provided by the fluidised bed and minimal froth results in low levels of bubble-particle detachment!
