Simple, low-rate feeder for water-insoluble flotation reagents [electronic resource] / L.L. Sirois and T. Takamori, Mineral Processing Division. Ottawa : Queen's Printer, 1966. iii, 9 p. : chart, ill. Technical bulletin ; TB 81 Cover title. "February 1966." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “A simple feeder to deliver water-insoluble flotation reagents in very small quantities was built. The action of this feeder is based on the regulated production of gases from the hydrolysis of water, to exert a positive pressure on a reagent and thus expel it at the required rate through a suitable feed arrangement. The accuracy of the feeder depends on the stability of the direct current produced, on the large quantities of minute gas bubbles formed at the electrodes in the hydrolysis cell, and on the formation of small drops of reagent at the feeding end. This feeder will deliver from 0.026 to 0.250 cc of solution or liquid per minute, with actual reagent-feed rates depending on dilution or specific gravity of liquid reagents"--Abstract, p. i.
