1. Kupatukana kwa nitric acid kuti itulutse golide, kupatukana kwa nitric acid kungagwiritsidwe ntchito, nitric acid yowunjikana mu beakers, kufunika kotulutsa golide mu chitsulo mu beakers. Kenako Beaker imayikidwa pa chogwirira beakers ndikutenthedwa ndi nyali ya mowa kuti ipange golide wosweka.

2. Kupatula aqua regia kuwonjezera pa kuchotsa golide, kulekanitsa aqua regia kumagwiritsidwa ntchito. Pambuyo posakaniza gawo limodzi la nitric acid ndi magawo atatu a hydrochloric acid mu aqua regia, zitsulo zomwe ziyenera kuchotsedwa zimayikidwa mu aqua regia ndikusefedwa pambuyo poti chitsulo chatha. Kenako chimatenthedwa ndipo pamapeto pake chimasinthidwa ndi mapepala amkuwa, omwe amathanso kuchotsedwa mu golide.

3. Njira yolekanitsa H2SO4 imasakaniza H2SO4 ndi H2O4 mu chiŵerengero cha chimodzi ndi chimodzi, kenako imayika ukadaulo wofunikira kuti ukonzedwe mu yankho la H2O4, ndikudikirira kuti chitsulocho chithe, chinthu chachikasu chachitsulocho ndi chagolide.

Zipangizo zopangira golide zomwe poyamba zinkachokera ku golide, makamaka kuchokera ku golide, miyala yokhala ndi golide yomwe imakumbidwa kuchokera ku migodi ya golide, yomwe ilinso ndi zitsulo zina zamtengo wapatali. Monga tonse tikudziwira, golide amagwiritsidwa ntchito kwambiri muzipangizo zamagetsi, zodzikongoletsera, mabatire, filimu yachipatala, mawaya, ndi zina zotero. Chifukwa chake tsopano zinyalala zamagetsi, zinyalala zodzikongoletsera zimathanso kukhala golide woyengedwa ndi zitsulo zina zamtengo wapatali. Kuyeretsa golide ndi njira yochotsera zinyalala kuchokera ku bullion kapena golide wosakaniza m'magulu kuti zinthu zagolide zikwaniritse zofunikira za miyezo ya malonda a golide.

Mukapanga ufa kapena ma flakes, mungagwiritse ntchito makina opangira ufa wachitsulo a Hasung ndi makina opangira ma flakes achitsulo kuti muyeretse golide. Mukamaliza kuyenga, gwiritsani ntchito makina opangira mipiringidzo yagolide a Hasung kuti mupeze mipiringidzo yagolide yonyezimira.
