Gravity Separation an overview ScienceDirect Topics
Abstract Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. This chapter describes units, circuits, and strategies that are used to recover gravity recoverable gold from very high grade gold particles and from sulfidic particles with low grade gold content.
Gravity Separation Principle, Uses and Applications ...
The gravity separation process is used to separate ore minerals. It is an old dressing technic for ore concentration. The concentration is achieved either by gangue removing or valuable minerals recovering. It is mostly applicable for coarse liberated ores, and it

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 smaller the particles processes, the greater the theoretical grade and recovery of the final product, but this however is difficult to do with fine particles as they prevent certain concentration processes from occurring. Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run of mine" ore, while grinding may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive. Sizing is the general term for separation of particles according to their size. The simplest sizing process is screening, or passing the particles to be sized through a screen or numbWikipedia · Text under CC BY SA license
How Gravity Separation Works to Recover Metals and Minerals
Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force, the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply, just at a smaller scale. Dense particles will settle first, and light ones ...
