Dry separation of iron minerals from low-grade coal-series kaolin
Dry separation of iron mineral from low-grade coal-series kaolin in Hubei Province of China was investigated. The structure and chemical composition of the kaolin ore were determined by X-ray diffraction (XRD) and X-ray Fluorescence (XRF) analyses. The narrow particle size range classification, dry magnetic separation and calcination were carried out to …
Basics of mineral processing - SlideShare
Operations are drilling (blasting), primary crushing (optional) and materials handling, dry and wet. 5. 5 Drilling (and blasting) is the technology of achieving primary fragmentation of "in situ" minerals. This is the starting point for most mineral processes with the exception of natural minerals in the form of sand and gravel.
