"A simple and rapid method has been developed for determining the relative saturation of air in the alkaline solutions used in processing uranium ores and gold ores. The method is based on the diffusion current produced by oxygen from the dissolved air when a sample of the solution ie subjected to a controlled potential applied to a calomel anode and a platinum cathode. Since the diffusion current is proportional to the relative saturation of air in the solution, and since only relative saturation levels are required for mill control work, it is sufficient to apply a fixed potential and to measure the diffusion currents with a microammeter"--Abstract. gccst Metals gccst Chemicals Ingraham, Thomas R., author.
