A term used to describe a surface that seems to prefer contact with water
to contact with air. In flotation, minerals with a water-avid surface will
not float, while those with an air-avid surface will. The object of
reagent additions in flotation is to form a water-repellent surface on the
minerals to be floated and a water-avid surface on the minerals that are
not to float (hydrophilic). CF:air-avid surface
