Mu nganda z'ikoranabuhanga, gukora neza ni ingenzi cyane, cyane cyane mu gukora imbuga zacapwe (PCBs). Granite ni inkingi y'ubu buryo bwiza kandi ni kimwe mu bikoresho bishimishije cyane. Ubumenyi bw'uruhare rwa granite mu gukora PCB ni uruvange rutangaje rw'ubumenyi bw'isi, ubuhanga n'ikoranabuhanga.
Granite ni ibuye karemano rigizwe ahanini na quartz, feldspar, na mica ritanga ituze n'ubudahangarwa budasanzwe. Iyi miterere ituma granite iba ibikoresho byiza byo gukora ubuso bwa PCB. Ubugari n'ubudahangarwa bw'amatafari ya granite bitanga urubuga ruhamye rw'ibikorwa bigoye bikorerwa mu gukora PCB, nko gufotora no gushushanya. Gutandukana kose mu bugari bw'ubuso bishobora guteza amakosa akomeye mu guhuza ibice, bigahungabanya imikorere y'umusaruro wa nyuma.
Byongeye kandi, ubushyuhe bwa granite ni ikindi kintu cy'ingenzi. Mu gihe cyo gukora PCB, ubushyuhe bukoreshwa mu byiciro bitandukanye. Granite ishobora kwihanganira ubushyuhe bwinshi idahinduka cyangwa ngo ihinduke, bigatuma imiterere ya PCB ikomeza kuba myiza mu gihe cyose cyo kuyikora. Ubu bushyuhe bukomeza kuba bwiza mu bikorwa nko gushongesha, aho ihindagurika ry'ubushyuhe rishobora gutera imiterere mibi n'inenge.
Byongeye kandi, imiterere ya granite idafata imyenge irinda kwandura, ibyo bikaba ari ingenzi mu cyumba cy’isuku aho PCB zikorerwa. Umukungugu n’uduce duto bishobora kwangiza byoroshye inzira zoroshye zikoreshwa mu gukora PCB, kandi ubuso bwa granite bufasha kugabanya iyi ngaruka.
Muri make, ishingiro rya siyansi ry’ubuziranenge bwa granite mu gukora PCB riri mu miterere yayo yihariye. Ubudahangarwa bwayo, ubushyuhe bwayo budashobora gushyuha, n’isuku yayo bituma iba ibikoresho by’ingenzi mu nganda z’ibikoresho by’ikoranabuhanga, bigatuma PCB zikorwa ziba nziza kandi zizewe. Uko ikoranabuhanga rikomeza gutera imbere, nta gushidikanya ko granite izakomeza kugira uruhare runini mu gushakisha ubuziranenge mu gukora ibikoresho by’ikoranabuhanga.
