1. Ukuhlukaniswa kwe-nitric acid ukuze kukhishwe igolide kungasetshenziswa ukuhlukaniswa kwe-nitric acid, i-nitric acid egxilile ibe yizitsha zokubhaka, isidingo sokukhipha igolide ensimbini ibe yizitsha zokubhaka. I-Beaker ibe isibekwa esibambi se-beaker bese ishiswa ngesibani sotshwala ukuze kukhiqizwe igolide eliqhekekile.
2. Ukuhlukaniswa kwe-aqua regia ngaphezu kokukhishwa kwegolide, kusetshenziswa ukuhlukaniswa kwe-aqua regia. Ngemva kokuxuba ingxenye eyodwa ye-nitric acid kanye nezingxenye ezintathu ze-hydrochloric acid ku-aqua regia, izinsimbi ezidinga ukukhishwa zifakwa ku-aqua regia bese zihlungwa ngemva kokuba ukusabela kwensimbi sekuphelile. Bese kuyashiswa bese ekugcineni kuthathelwa indawo ngamashidi ethusi, angakhishwa nasegolideni.
3. Indlela yokuhlukanisa i-H2SO4 ixuba i-H2SO4 ne-H2O4 ngesilinganiso senye kuya kwenye, bese ibeka ubuchwepheshe obudingekayo ukuze buhlungwe kusisombululo se-H2O4, bese ilinda ukuphela kokusabela kwensimbi, into ephuzi yensimbi iyigolide.
Izinto zokusetshenziswa zokukhishwa kwegolide ngaphambilini izinto zokusetshenziswa zokukhishwa kwegolide zazivela kakhulu ensimbini yegolide, insimbi ephethe igolide embiwe ezimayini zegolide, equkethe nezinye izinsimbi eziyigugu. Njengoba sonke sazi, igolide lisetshenziswa kabanzi ezintweni ze-elekthronikhi, ubucwebe, amabhethri, ifilimu yezokwelapha, izintambo, njll. Ngakho-ke manje imfucuza ye-elekthronikhi, imfucuza yobucwebe nayo ingaba yigolide elicwengisisiwe kanye nezinye izinsimbi eziyigugu. Ukucwengisisa igolide inqubo yokususa ukungcola egolideni eliyi-bullion noma elixutshwe ngamaqoqo ukuze kuvunyelwe imikhiqizo yegolide ukuhlangabezana nezidingo zekhwalithi zezindinganiso zokuhweba ngegolide.
Uma wenza i-powder noma ama-flakes, ungasebenzisa umshini wokwenza i-Hasung metal powder kanye nomshini wokwenza ama-flakes ensimbi ngenhloso yokucwenga igolide. Ngemva kokucwenga, sebenzisa umshini wokukhipha ama-gold bar e-Hasung ukuze uthole ama-gold bar acwebezelayo.
