There are a number of other considerations when it comes to the Hashing stage. Stages 1 and 2: Bashing and Mashing. Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball-milling, or single-stage crushing followed by a Semi-Autogenous (SAG) mill and ball mill.
