mathematical-petrographic rock characterization as support,effect on the beneficiation process. the knowledge about the precise correlations between microstructure and behavior during beneficiation is, however, relatively limited. one important reason is the fact that the present state of textural and structural characterization of the ores in most cases allows only for a verbal description..the importance of concrete recycling,processing begins with primary jaws, cones and large impactors designed to reduce concrete debris in size. this step may or may not be followed by the use of secondary cone or impactors for further processing. dirt and foreign particulate may be removed by a scalping screen while the fine material may be removed with a fine hard deck screen..ammaroo phosphate feasibility study completed,a 20/90 frances bay drive, stuart park nt 0820 p gpo box 775 darwin nt 0801 establishment of early stage processing at ammaroo has the potential to be the precursor to the phosphate needle structures and a soft ore which produced excessive fines during beneficiation. these fines are discarded as waste product thus reducing the p 2 o 5.(pdf) size reduction by crushing methods,they are: 1) comminution – the process of particle siz e reduction; 2) sizing – separation of particle sizes by screening or classification; 3) concentration by taking advantage of physical.
