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
