The 5 Main Steps in Processing Diamond Ore | .

12.11.· The first step in kimberlite ore processing is crushing. This process reduces large runofmine 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

Crushing Vs GrindingMinerallurgy

Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation. For example, hard rocks that come from blasting can be big as 1m in size, and require multiple stages of crushing and grinding. In addition, if the valuable mineral is finely disseminated in the ore the grinding size can be down to 40 microns, which can be
