sand and gravel flotation optimization
OPTIMIZATION STUDIES FOR THE FLOTATION OF BUNKER …
Sand was initially air-dried overnight to remove moisture content. Dry sieving was then carried out to remove the debris (leaves, wood, stones and gravel) and to separate the sand into its respective particle sizes (1000 μm, 500 μm, 250 μm, 125 μm) using a Retsch AS 200 sieve shaker. An oil-wet sand condition were prepared by mixing a

Lesson 3: Sedimentation and Flotation
A drying bed is similar in design to a sand filter, with a layer of sand underlain by a layer of gravel. The sludge is applied to the top of the sand and the water percolates down through the sand and gravel and is drained away. When the sludge is sufficiently dry, it is carefully removed from the top of the sand and is trucked to a landfill.
