Which is better: dry or wet machining? | Cutting Tool ...

When near-dry milling with MQL, the tool's cutting edge works inside a mist formed from oil and compressed air, which is sprayed directly into the cutting zone. Depending on the design of a machine tool and milling cutter, the mist is delivered externally or internally through the cutter. The main function of MQL is to lubricate the cutting edge.

Dry Processing - Vale

Dry stacking. To reduce the use of dams, Vale plans to invest almost R$1.5 billion (US$390 million) for implementation of dry tailings stacking technology in Minas Gerais between 2020 and 2023. The technique allows filtering and reusing water from the tailings so that tailings can be stacked, thus reducing the use of dams.

Ball Mill. Ball mills can operate in either wet or dry conditions. They are advantageous because they can achieve a very fine particle product size (refer to Table 1). Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small.
