Wet beneficiation systems process fines by several' types of unit operations, but usually must also incorporate costly and complex dewatering systems to reduce the moisture content of the products. Existing pneumatic preparation systems are constrained between product equality and yield by the sharpness of separation. These limitations become more severe with decreasing particle size and increasing feed moisture content. Control of particulate emissions, both process and fugitive, during pneumatic preparation, can be forbidding. A pneumatic preparation-process which would overcome these constraints, could be most enticing.

As most ores mined today are low-grade ores-that is, they contain only a small percentage of valuable metals-a large bulk of material must be treated... Therefore methods are used to... remove as much of the worthless part as possible. This is called mineral beneficiation...  1, record 20, English, - mineral%20beneficiation

Treatment of ores to concentrate their valuable constituents(minerals) into products(concentrate) of smaller bulk, and simultaneously to collect the worthless material(gangue) into discardable waste(tailing). The fundamental operations of ore-dressing processes are the breaking apart of the associated constituents of the ore by mechanical means(severance) and the separation of the severed components(beneficiation) into concentrate and tailing, using mechanical or physical methods which do not effect substantial chemical changes.  3, record 21, English, - ore%20dressing
