Abstract
CONTROL of hydrogen ion concentration in metal flotation, electrolytic reduction, and electrolytic refining processes has usually been accomplished by the expensive, slow, and inaccurate methods of colorimetric analysis and manual control. The desirability of automatic regulation of the concentration of these chemicals has been apparent for a long time but no method of regulation has been suggested that meets all the requirements.
