minerals separation process

minerals separation process

A flotation process based on surface-tension phenomena, accelerated by means of addition to the pulp of small quantities of oil and air in minute subdivision. Only about 0.1% oil is added, and the pulp is violently agitated for 1 to 10 min. Innumerable small bubbles of air are thus mechanically introduced, which join the oil-coated particles. These are then removed in a spitzkasten. Exposure to the air after this treatment then 2010 aerates any mineral that has not already taken up its oil film, after which a second spitzkasten treatment removes this. An early name for froth flotation.
