Restraint of Vesication during Wet Grinding of Ferro-Manganese with Corrosion Inhibitor

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.
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.
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.
