Pegmatite Rock Processing Plant
The pegmatite rock processing plant is to produce maximum value from a given raw material. This goal can be a crushed product with certain size and shape or maximum recovery of metals out of a complex ore. The technologies to achieve these goals are classical, complementary and well defined.
A machine working in a pegmatite rock processing flow cannot perform better than the process environment will allow it to. Parameters like type, size and amount of feed, % solids in slurries, additives, discharge conditions etc. will always guide equipment performance and operation economy.
Extraction, beneficiation, and processing of pegmatite rock produces rock ore. "Extraction" is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. "Beneficiation" of rock ore includes concentration, generally by physical removal of unwanted gangue; also considered beneficiation is the regulation of product size, or other steps such as agglomeration to improve its chemical or physical characteristics prior to processing. "Processing" of the concentrated product into rock ore typically involves the use of pyrometallurgical techniques.
The choice of pegmatite rock processing equipment depends on the type and amount of feed material to be crushed. Jaw crushers as primary crushers used at mining operations today, although some operations use impact crushers, low-speed roll sizers and feeder breakers. Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.
Processing pegmatite rock before export or local sale adds value to them. In cases where minerals are mined primarily for export, pegmatite rock processing will ensure that the tailings which may contain some yet unidentified minerals and known valuables that cannot be concentrated by the present methods are left in place until an improved technology for their efficient recovery and identification of all components is developed.
