Wet vs. dry As a rule of thumb, operations look to reduce drying requirements for obvious cost implications. Employing wet magnetic separation early in a process can greatly benefit an operation if a low-grade final tailing, or a clean marketable product, can be produced, since it alleviates both drying and dry storage costs.
