Ore processing TESCAN

Ore processing. Different ore textures, as well as different mineralogy of the ore, can cause significant changes in the plant performance. Automated Mineralogy (AM) is a very important diagnostic tool in extractive metallurgy as it adds ore and particle mineralogical properties to traditional bulk mass, chemical and XRD data.
