    Examples of such are magnetite, ilmenite, pyrrhotite, pyrite and millerite. Because these are heavy, they often conglomerate in certain locations of the body of magma, a known as differentiation, and may form substantial bodies of ore.

    Screening and grading: The useful minerals are selected in the crushing process or graded by size. Ore Dressing The ore will be sorted after being crushed and the useful minerals and gangue are selected, or the various useful minerals are separated from each other, which is the main part of the beneficiation. The ore dressing methods include magnetic separation, gravity separation, froth flotation, …

    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 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 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 normally carried out after crushing 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 numb…

     · There are various methods of formation. The general way are formed is through the of crystallization. There are many different example of this, including through the crystallization of magma or the crystallization of lava. The crystallization of magma cools inside the crust, while the crystallization of lava cools and then hardens on the surface.
