Q&A about Grinding Circuits - Rhosonics

08/04/2021· The grinding circuit is the most expensive part of the mining process, because they consume a lot of energy, it is a high intensity energy environment. They also consume a lot of steel and grinding media. The consumption of grinding media is a significant part of the costs of the mineral processing plant. When operating with low density values, the efficiency of this circuit will be affected.
