Our view

For a first hard-rock gold plant in the 5 to 15 t/h range, a 1.5 × 5.7 m tube mill in closed circuit with a classifier is the usual starting point. Smaller batch mills suit pilot plants and cooperatives moving from alluvial to primary ore.

Mills are supplied with drive, lining and media specification matched to the ore. We size the mill from grindability test work, not from a catalogue row.
