Mineral dressing (= Orebeneficiation)

Mineral dressing Since most ore minerals are usually finely disseminated and intimately associated with gangue minerals, the various minerals must be broken apart (freed) or liberatedbefore they can be collected in separate products. Therefore, the first part in any ore dressing process will involve the crushing and grinding (which is also known by a common name called comminution

Mineral processing

Other equipment used historically includes the hutch, a trough used with some ore dressing machines and the keeve or kiekkkve, a large tub used for differential settlement. Unit operations. Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking

Geotechnical Consideration an overview ScienceDirect

Detailed sedimentological logging and facies interpretations allow for an understanding of the depositional environment and aid in the interpretation of the geotechnical environment, allowing for better understanding of the rock mass behaviour during mining operations (Van Heerden, 2004a). It is the senior author's experience that far too few borehole logs have sufficient detail to correctly
