ABOUT THIS PHOTOGRAPH. Bernard Hoffman, one of the nation's leading science photographers, used a 4 χ 5 Gamma microscope cam- era with a 21 mm Cook lens to record this impression of a Hercules rosin amine derivative as a flotation agent. Magnification was 110 diameters and the photo was shot at 1/10,000 of a second. Strobe flash and polarized light were used. The photograph was taken 3/8 of an inch from the subject.

A New Looh at Rosin Amine Through the Camera's Eye
(one of a series)
Adsorption to Siliceous Surfaces EXAMPLE: Flotation
Looking like a magic wonderland, this is really a greatly magnified view of flotation in action—one of the useful applications for Rosin Amine D* and its derivatives.
By adsorption to siliceous surfaces, such as mica, feldspar, glass, Rosin Amine D and its derivatives form a molecular film tha t changes the surface properties of the substance. One result in aqueous solution is flotation of the silica in ore beneficiation. This property is shown in this photograph of sand flotation with Rosin Amine D Acetate. Rising bubbles float the sand to the surface. Some bubbles carry only a few particles, while others are covered with floes of the arnine-coated silica.
There are other applications for this property of Rosin Amine D and its derivatives including its use as additives in Road Asphalts, Mastic Cement and Ceramic Inks.
The wide range of basic properties provided by Rosin Amine D and its derivatives offers many opportunities to create new products or improve established ones. Rosin Amine also adsorbs to metallic surfaces, provides surface activity, and control of microbiological organisms. The amine derivatives are available in oil-soluble, water-soluble, and acid-soluble types.
