1. Ukwahlulwa kwe-nitric acid ukuze kukhutshwe igolide kungasetyenziswa ukwahlulwa kwe-nitric acid, i-nitric acid edibeneyo ibe ziibhika, imfuneko yokukhupha igolide kwisinyithi ibe ziibhika. Emva koko iBeaker ibekwa kwisibambi sebhika ize ifudunyezwe ngesibane sotywala ukuze ivelise igolide eqhekekileyo.
2. Ukwahlulahlula i-aqua regia ukongeza ekutsalweni kwegolide, kusetyenziswa ukwahlulwahlula i-aqua regia. Emva kokuxuba inxalenye enye ye-nitric acid kunye namacandelo amathathu e-hydrochloric acid kwi-aqua regia, iintsimbi ezifuna ukukhutshwa zifakwa kwi-aqua regia kwaye zihluzwe emva kokuba i-reaction yesinyithi iphelile. Emva koko iyafudunyezwa ize ekugqibeleni ithathelwe indawo ngamashiti obhedu, anokukhutshwa nakwigolide.
3. Indlela yokwahlula i-H2SO4 ixuba i-H2SO4 kunye ne-H2O4 ngomlinganiselo wesinye ukuya kwesinye, emva koko ibeka ubuchwepheshe obufunekayo ukuze bucocwe kwisisombululo se-H2O4, ize ilinde ukuphela kwempendulo yesinyithi, into etyheli yesinyithi yigolide.
Izinto ezisetyenziswa xa kutsalwa igolide ngaphambili izinto ezisetyenziswa xa kutsalwa igolide zazivela kwi-ore yegolide, i-ore enegolide eveliswe kwimigodi yegolide, ekwaqulathe nezinye izinyithi ezixabisekileyo. Njengoko sonke sisazi, igolide isetyenziswa kakhulu kwizinto ze-elektroniki, ubucwebe, iibhetri, ifilimu yezonyango, iintambo, njl.njl. Ngoku ke inkunkuma ye-elektroniki, inkunkuma yezinto ezixabisekileyo inokuba yigolide ecociweyo kunye nezinye izinyithi ezixabisekileyo. Ukucocwa kwegolide yinkqubo yokususa ukungcola kwi-bullion okanye igolide exutyiweyo kwiibhetshi ukuze iimveliso zegolide zihlangabezane neemfuno zomgangatho wemigangatho yorhwebo lwegolide.
Xa usenza umgubo okanye iiflekhi, ungasebenzisa umatshini wokwenza umgubo wesinyithi waseHasung kunye nomatshini wokwenza iiflekhi zesinyithi ngenjongo yokucokisa igolide. Emva kokuba ugqibile ukucokisa, sebenzisa umatshini wokwenza iibheyi zegolide waseHasung ukuze ufumane iibheyi zegolide ezikhazimlayo.
