Relationships with occupations

Essential knowledge

Froth flotation processes is an essential knowledge of the following occupations:

Froth flotation deinking operator: Froth flotation deinking operators tend a tank that takes in recycled paper and mixes it with water. The solution is brought to a temperature around 50°C Celsius, after which air bubbles are blown into the tank. The air bubbles lift ink particles to the surface of the suspension and form a froth that is then removed.

Optional knowledge

Froth flotation processes is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Wash deinking operator: Wash deinking operators operate a tank where recycled paper is mixed with water and dispersants to wash out printing inks. The solution, called a pulp slurry, is then dewatered to flush out the dissolved inks.
