A new highcapacity flotation technology, the StackCell, has been developed as an alternative to both conventional and column flotation machines. This technology makes use of a preaerated, highshear feed canister that provides efficient bubbleparticle contacting, thereby substantially shortening the residence time required for coal flotation.

from mineral processing flotation cells. A flotation cell is a reactor in which the three phases: solid, liquid, and gas, interact to separate valuable minerals that contain saleable metals, and waste minerals called gangue. In the case of mineral flotation, the solid is the ground rock particles, the liquid is water, and the gas is usually air.
More ores are treated using froth flotation cells than by any other single machines or process. Nonmetallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal.
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.
At Universal Foam, were ready to help you build your floating boat dock or party deck. The marine environment can be challenging, but expanded polystyrene (EPS) floatation blocks have withstood the test of time. Often confused with STYROFOAM Brand Foam, EPS is lightweight and extremely buoyant, can be shaped and molded to fit the demand of marine construction and it holds up under
