Intensified industrialization and human activities have resulted in the release of various contaminants into the environment. Among them, heavy metals are often present as a result of mining, milling and industrial manufacturing. In the present investigation, bulk concentrations Pb, Cd, Zn, Cu, Fe, Ca and Al in Shur River (Iran) bed sediments and water around the Sarcheshmeh copper mine were me...

A significant challenge in mineral raw materials comminution is the improvement of process energy efficiency. Conventional techniques, although globally used, are far from being considered power-efficient. The use high-voltage electric pulses a concept that worthy study; despite its lack industrial-scale validation after several decades lab-scale research, it seems promising as pretreatment lea...

Abstract. Impact fragmentation is the underlying principle of comminution milling of dry, bulk solids. Unfortunately the outcome of the fragmentation process is more or less determined by the dimensionality of the impactor and it’s impact velocity, prohibiting the adjustment of desired fragment distributions. By modifying target shapes or impact angles, differences in the fragment mass distribu...
