| Abstract: | A special cell was designed to study mechanical electrochemistry phenomena in grinding environment. It was found that the grinding media type and mechanical pressure have a pronounced effects on the potential and current of the mineral surfaces; The electrode potential of galena decreases with the increase of mechanical pressure on it and changes with the different grinding media following the order of iron >sphalerite>pyrite. The results show that these effects can change activity of surface, which have an important effect on reaction mechanism. |
