Refinement - MIT

Overview. Refinement is the process that mined material undergoes so as to remove all undesirable minerals and separate the desired elements. Because the global issues concerning platinum group elements, radioactive minerals, rare metals, lithium and phosphorus result primarily from a lack of distribution as opposed to a lack of production efficiency, Mission 2016 did not work to improve ...

The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production. The process

Refining minerals Mining of mineral resources Siyavula

Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock. The unwanted rock is called waste rock. The choc chips are separated from the rest of the biscuit, just as minerals are extracted from the rock.

Mineral processing - Wikipedia

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
