AMIT 135: Lesson 6 Grinding Circuit Mining Mill Operator

To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral fractions by increasing the specific surface. Grinding takes place in more “open” space which makes the retention time longer and adjustable compared to crushers.
