Iindlela zokuMisela ukuQonda kweZircon kwiGranite
Ukulinganiswa koxinzelelo lwe-zircon kwi-granite kuqala ngokwahlukana kolwelo olunzima, kusetyenziswa i-methylene iodide, ehlukanisa iikristale ze-zircon. Ukubala nokulinganisa ezi nkozo kuvelisa ubuninzi be-zircon obusekelwe kubunzima, kodwa ubunzulu bomsebenzi kunye nokutshatyalaliswa kwesampulu ziingxaki ezinkulu. Iindlela ezingonakalisiyo, njenge-X-ray fluorescence (XRF), zihlalutya iisampulu ze-granitic eziqinileyo ngaphandle kokunyibilika kweekhemikhali.
Iziseko ze-X-Ray Fluorescence (XRF) kuHlalutyo lweziMbiwa
I-XRF isebenza ngeeathom ezinomdla kwi-granite, nto leyo ebangela ukuba i-emission spectra ilingane nobuninzi bezinto ezisisiseko. I-Lonnmeter XRF analyzer ibona i-Zr, yahlula i-zircon kwezinye iiminerali ze-granite ngomxholo wazo we-Zr owahlukileyo. I-XRF ilinganisa izinto ezininzi kwi-granite rocks kwimizuzwana embalwa, ixhasa ukuhlolwa ngokukhawuleza kwe-granite enomxholo ophezulu we-zircon. Ukulungiswa kwesampuli kuncinci; ii-slabs eziqinileyo okanye ii-powders zanele. Esi sixhobo sixela ubuninzi be-Zr obuchanekileyo, okuvumela ukuchongwa ngokukhawuleza kwe-granite ene-zircon. Ngokungafaniyo nokunyibilika kweekhemikhali, i-XRF igcina ukuthembeka kwesampuli, inciphisa umngcipheko wongcoliseko. I-Zr ephakanyisiweyo yi-XRF idla ngokuxilonga ubuninzi be-zircon mineral kwi-granite, nangona iindlela ezongezelelweyo zifuneka ukuze kubekho inani elipheleleyo leengqolowa.
Uthelekiso lwexesha, ukulungiselela isampuli, kunye neenzuzo zohlalutyo olungonakalisiyo lwe-XRF ngokuchasene neendlela zokwahlula ngokwesiko kunye neendlela zohlalutyo lwe-microanalysis ze-zircon ekwakhiweni kwe-granite.
