In some cases, ore beneficiation is not considered necessary and/or economical. However, this does not mean value cannot be extracted from the ore via other methods, such as implementing a direct chemical decomposition of the mineral. Forgoing beneficiation techniques with some ores, such as eudialyte group minerals, may be …

11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

Chromite Beneficiation Process. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely …
