Location: Gold, Minerals processing plants. A cyclone always operates with a size classification mechanism, but depending on the way a cyclone is used, it can be named differently: Dewatering Cyclone: If the feed is fairly coarse, the cyclone will split almost all of the water, with very little solids to the overflow.
Normally, kaolin processing is better performed in the wet state, where the raw kaolin is highly pulverized to meet the size necessary for the pharmaceutical grade particle kaolin. Kaolin slurry is prepared by mechanical blunging of 35–70% kaolin-water suspension for particles disaggregation with chemical dispersant (e.g. sodium ...
The use of calcined clays as supplementary cementitious materials provides the opportunity to significantly reduce the cement industry's carbon burden; however, use at a global scale requires a deep understanding of the extraction and processing of the clays to be used, which will uncover routes to optimise their reactivity.
