Abstract

An effective method for restraint of vesication during wet grinding of ferro-manganese by the addition of a corrosion inhibitor to the reservoir in the process has been developed.<BR>In the wet grinding of ferro-manganese, a large quantity of malodorous foam is produced due to gases liberated by the oxidation reactions between ferro-manganese and water. It is possible to explain these phenomena successfully from the viewpoint of corrosion science.<BR>As the result of investigations of physical, chemical, and electrochemical considerations with some experiments, it was concluded that the addition of polyphosphate was the most effective solution to the problem.
