Mechanical activation by grinding is a complex process involving alteration of structure, chemical composition and properties of solid substances. In this article the characteristic features of mechanically induced changes in minerals with close packed anion sublattice are illustrated on the example of planetary and vibration ground chalcopyrite. Summarizing the results of a longlasting research...
The influence of mill power and grinding environment on the contamination of quartz by iron during vibration grinding was studied. It was found that the Fe content of ground powders increased with an increase in specific grinding energy that was independent of the conditions of energy supply, that is whether it was supplied by varying the mill power or the grinding time. The specific contamination...
