Processes for the dry processing of at-minerals
01.05.2018· Summary: The development of recycling processes for the use of material resources from industrial waste products or by-products is becoming more and more important. To this end, comminution processes play a key role in processing the material in such a way that recyclable materials become exposed for subsequent separation processes.
Mineral processing Wikipedia
Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material.

Since wet grinding is the most common method for particle size reduction and mineral liberation, there is a lack of understanding about the effects of dry grinding on downstream separation processes such as flotation. This manuscript compiles various effects of dry grinding on flotation and compares them with wet grinding. Dry grinding consumes higher energy and produces wider particle size
Future-proofing your grinding circuit with dry HPGR and
Moreover, dry grinding by HPGR prevents oxidization of particle surfaces and introduces less grinding media contamination into the process compared to conventional grinding, which in turn enhances mineral recovery. In a market where many believe “water is the new oil,” utilizing HPGR and dry classification technology can go a long way to future-proofing your grinding circuit.
