Ithiyori ye-Fire Assay kanye nendlela

2021/12/24

Ukuhlola umlilo kuyinqubo evamile yemboni yokuthola idatha ye-analytical gold and platinum element (PGE) kusuka ku-ore yezinga eliphezulu. Kuyinqubo eyenziwe yesimanje kodwa ngendlela yayo elula, sekungamakhulu eminyaka isetshenziswa. Ukuhlolwa komlilo kusetshenziswa ekunqumeni igolide kuzo zonke izinhlobo zesampula, okuhlanganisa i-drill core, inhlabathi namasampula e-chip.


UHLELO

I-FUSION

Isampula ehlutshiwe iyakalwa futhi ihlanganiswe ne-ejenti eguquguqukayo. I-flux isiza ekuncibilikeni, isiza ukuhlanganisa isampula ezingeni lokushisa elifanelekile futhi ikhuthaze ukuhlukaniswa kwempahla ye-ganggue ezinsimbi eziyigugu. Ngaphezu kwe-flux, i-lead noma i-nickel yengezwa njengomqoqi. Isampula libe selishiselwa esithandweni lapho lihlangana khona futhi lihlukane ‘nenkinobho’ yezinto zomqoqi, equkethe amaminerali ayigugu.


UKUKHISHWA KWEMETALI EBALULEKILE

Uma inkinobho isihlukanisiwe ne-ganggue, izinsimbi eziyigugu zikhishwa kumqoqi ngenqubo ebizwa ngokuthi i-cupellation. Uma inkinobho isipholile, ihlukaniswa ne-slag futhi


i-cupelled.

• Uma umthofu usetshenziswa njengomqoqi, umthofu ukhipha i-oxidize bese ufakwa ekhabetheni ushiye ubuhlalu bensimbi obuyigugu. Ubuhlalu bube sebuchithwa ku-aqua regia ukuze buhlaziywe.

• Uma i-nickel isetshenziswa njengomqoqi, inkinobho iyachotshozwa bese incibilika ku-hydrochloric acid bese kuthi insalela ihlungwe ukuze kukhishwe izinto ezingaphandle, kushiye insalela yensimbi eyigugu esisefweni.


UKUHLAZIYA NOKUTHOLA

Igolide ne-PGE kungahlaziywa ngabaningana


izindlela:

UKUMUMVA KWE-FLAME ATOMIC (AA)

• Isampula lichithwa ku-aqua regia bese lishiswa elangabini le-acetylene. Umsebe wokukhanya olingana nowegolide udlula elangabini. Igolide kusampula limunca ukukhanya ngokulinganayo kuye ngokugxila kwe-elementi esixazululweni. Ukumuncwa kuqhathaniswa nezixazululo ezijwayelekile zokunquma ukugxiliswa kwegolide kusampula.


I-PLASMA-ATOMIC EHLANGANISIWE NGOKUHAMBISANA

I-EMISSION SPECTROMETRY (ICP-AES)

• Isampula elinamanzi lishiselwa ku-plasma futhi igolide eliqukethwe kusampula likhipha ukukhanya kumaza wamaza. Ukuqina kokukhanya okukhishiwe kukalwa futhi kuqhathaniswe nesofthiwe nalawo ezixazululo ezijwayelekile ezinegolide. Isofthiwe ke

ibala ukugxiliswa kwegolide kusampula.

I-PLASMA-MASS EHLANGANISIWE NGOKUHAMBISANA

I-SPECTROMETRY (ICP-MS)

• Igolide eliqukethwe kusampula elinamanzi lifakwe ionini. Ukuqina kwesiginali ku-mass 186 kuyalinganiswa, kanye nezimpawu zanoma yimaphi ama-isotopes angaba nokuphazamisa. Amandla ku-186µ akalwa futhi aqhathaniswe nesofthiwe nalawo egolide elijwayelekile- ezithwala izixazululo zokunquma ukugcwala kwegolide kusampula.


UKUSEBENZA KWE-ISTRUMENTAL NEUTRON

UHLAZIYO (INAA)

• Okusele kukhishwa ephepheni lokuhluza bese kukhanyiswa kumongo wereactor yenuzi. Izakhi eziningi ziba nemisebe futhi zikhiphe i-gamma- imisebe ye-ray yamaza amaza athile.

Amaza egolide ayalinganiswa futhi aqhathaniswe nezindinganiso zegolide ukuze kunqunywe

ukugcwala kwegolide kusampula.


I-SCREENED METALLICS

Igolide nge-screened metallics fire assay liqukethe ukuhlola u-500g wesampula kuma-microns angu-106. Ingxenye yokuhlanganisa iwukuhlolwa komlilo ukuze kutholwe igolide futhi ukuhlolwa okuyimpinda kwenziwa kungxenyana yokususa. Isisindo sengxenye kasayizi, okuqukethwe kwegolide okuyingxenyana eqinile kanye nengqikithi yegolide kuyabikwa.
