Gravity Separation Principle, Uses and Applications

Gravity separation, also known as gravity concentration in mineral processing, is a technique of separating valuable minerals from gangue, based on their specific weight differences. It is applied using water, particular liquids, or even air. The process of concentrating ores using gravity separation has many advantages.

OverviewUnit operationsHistoryOther processnferencesSee alsoNotesSources

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 advantage of physical and surface chemical properties and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle
