flotation process in chemistry

Aug 06, 2010·Flotationis a highly efficient method of removing suspended oil from water when the load is less than 100 ppm and emulsions do not exist. Increasing amounts of oil are left in the water as the incoming load increases. Theflotation processhas the following shortcomings: 1. …

Flotation Froth - an overview | ScienceDirect Topics

The froth flotation process is commonly employed for the selective separation of a mineral species from a liquid–solid suspension of both valuable and unwanted gangue mineral particles. The valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles.
