The 5 Main Steps in Processing Diamond Ore
The first step in kimberlite ore processing is crushing. This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps. Crushing is done in stages to “gently” free the diamonds from the kimberlite rock and produce a target size, usually less than 25 mm, for further processing. You
