Size Distribution Copper Ore

Effects of impact and attrition mechanisms on size ...

2021-8-18  Feed size distributions of the samples. Within the tested samples, magnetite had the finest size distribution and copper ore was the coarser one. For the mixtures, the size distributions varied accordingly. In this regard, calcite-magnetite had finer size distribution than calcite-clinker owing to the characteristics of the raw samples.
