The dual extraction column (DEC) principally resembles column flotation but differs in terms of height and bubble injection . It is a high efficiency flotation device which handles slurry feeds with wide particle size. The DEC combines low capital and operating costs. Designed for high through put with unique bubble generator to offer the advantages of low power and water usage and operates as a rougher and scavenger in one unit. The DEC is anti choking and restarts immediately after the power or plant outage. Since height of the DEC is comparatively small. it is useful to separate minerals with faster flotation kinetics.
