Corrosion Behavior of a Pyrite and Arsenopyrite Galvanic ...
known that the galvanic effect promotes the corrosion of arsenopyrite in the process of arsenical gold sulﬁde concentrate bio-pretreatment. In other words, the presence of pyrite accelerates oxidation of arsenopyrite [5–9]. In recent years, the galvanic mechanism of pyrite and arsenopyrite in different media has been discussed [14–18].

Galvanic cell - Wikipedia
Galvanic corrosion is a process that degrades metals electrochemically. This corrosion occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte, such as salt water, forming a galvanic cell with H 2 formation on the more noble metal. The resulting electrochemical potential then develops an electric ...Get Price
5 Ways to Prevent Corrosion of Metal Parts - .
Galvanic corrosion occurs when metal parts with two different electrode potentials are in contact along with an electrolyte like saltwater. This causes the metal with higher electrode activity to corrode at the point of contact. One can prevent galvanic corrosion by storing these parts separately. This effect can also work as an anti-corrosion measure, as explained below.Get Price
Galvanic Corrosion - NACE
Galvanic Corrosion. Galvanic corrosion (also called ' dissimilar metal corrosion' or wrongly 'electrolysis') refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte. It occurs when two (or more) dissimilar metals are brought into electrical contact under water. When a galvanic couple forms, one of the metals in the couple becomes the anode and ...Get Price
