The 5 Main Steps in Processing Diamond Ore | Multotec Canada

Here are the main steps in processing diamond ore. A number of these processes use equipment from Multotec: 1- Crushing 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.
