Oct 05, 2010· Older flotation cells use a displacement float below the froth layer to measure the pulp height. Pulp height is an important process measurement, used to ensure that liquid pulp is not allowed to overflow to the launders. If pulp overflows, the flotation cell ceases to function effectively, and this is very costly to the process.Read More
Reduction in Dust Emissions from Bauxite Operations.
