Сatalytic Acceleration of Supplied Corrosion Under Hypergenesis Conditions
Authors: ,
Abstract: Ecological safety of the natural environment depends on chemical activity in conditions of hypergenesis. The catalytic role of dispersed platinum in corrosion processes of metals and sulfide minerals was described. A sharp increase in the share of platinum in the slurry fraction is experimentally substantiated. The essential fact is that platinum is redistributed in a slurry even before sulfides of nonferrous metals and iron are completely oxidized. It was found that the main cause of the initial stage of sulfide corrosion is the process of pitting. It has been experimentally established that the accelerated corrosion on the sulfide surface is determined by the catalytic action of the metal causing activation of the anodic process.
