Fremgangsmåte og anordning for separasjon av urenheter fra en suspensjon ved flotasjon

摘要

The method for removing interfering substances from suspensions by flotation involves decompression of a gas-saturated liquid separately, before it is introduced into the suspension containing interfering substances. Also claimed is an apparatus for implementation of the method. It comprises a separate decompression unit (4), a unit (2) for enriching a liquid with a gas, and a flotation cell (6).
