Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed …

The Problem with Chromite Processing 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 …

The beneficiation method of tin ore is determined by its own characteristics. Because the density of cassiterite is higher than that of co-existing minerals, the traditional beneficiation process of tin ore is gravity beneficiation. With the passage of time, the granularity of cassiterite in the selected ore has been continuously reduced, so ...
