  Effect of ball and feed particle size distribution on the milling ...

  201861 · Fine grinding is believed to lead to high leaching rates as predicted by the common leaching models because value material gets more liberated hence requires less time to leach. However, this is associated with higher energy consumption and labor costs.

  A fundamental study of leaching kinetics and mechanisms of …

  2019115 · Higher temperature and longer leaching time were beneficial to Mo extraction. However, it was also found that too large grinding balls and high ball to powder mass ratio adversely affected MoS 2 extraction. The kinetics analysis indicated that the leaching of activated MoS 2 followed a chemical reaction controlled mechanism.
