The following are the steps and main advantages of the dry beneficiation method: 1. Ore crushing and grinding: Kaolin ore first needs to go through the process of crushing and grinding to reduce the ore particle size for subsequent separation operations. 2. Screening: The ore after grinding will be sent to the screening equipment and …
