Regrind Mills: Challenges of Scaleup Abstract
Larson. Different sizes and types of media were compared in water and grinding copper ore. This yielded the expected results – smaller media is more efficient, drawing less power in both water (Figure 7) and copper ore (Figure 8), so long as it breaks top size particles.

What is the best way to farm ore in Terraria?
3. For the first 4 ores, the deeper you go, the easier it is to find the better ones. Just above cavern layer is usually where iron/lead gets more common and silver/tungsten is in low quantities. Then poking around the caverns, while dangerous, will get you plenty of silver/tungsten and start assembling gold/platinum.

TITLE OF THE PAPER
1996). This indicates that it requires a fine grind to liberate the PGEs. Lidell et al. (1986) noted that the majority of the PGEs (70% by mass) in the Merensky ore were found to be between 150 and 38 m and therefore could be liberated with a much coarser grind as compared to the UG-2 ore. 2.2. Smelting of UG-2 ore and the effect of chromite
