1. Gutandukanya aside nitricike kugirango ikuremo zahabu itandukanyirizo rya acide nitric irashobora gukoreshwa, acide nitricike yibanze muri beakers, gukenera gukuramo zahabu mubyuma mubitereko.Beaker noneho ishyirwa kumufata inzoga hanyuma igashyushya itara rya alcool kugirango itange zahabu yuzuye.

2. Gutandukanya Aqua regia usibye gukuramo zahabu, gutandukanya aqua regia birakoreshwa.Nyuma yo kuvanga igice kimwe cya acide nitric hamwe nibice bitatu aside hydrochloric muri aqua regia, ibyuma bigomba gukururwa bishyirwa muri aqua regia hanyuma bikayungurura nyuma yicyuma kirangiye.Hanyuma irashyuha hanyuma igasimbuzwa impapuro z'umuringa, nazo zishobora gukurwa muri zahabu.

3. Uburyo bwo gutandukanya H2SO4 buvanga H2SO4 na H2O4 mukigereranyo cyumuntu umwe, hanyuma agashyira tekinoloji ikeneye gutunganywa mugisubizo cya H2O4, hanyuma agategereza ko iherezo ryicyuma, ikintu cyumuhondo ni zahabu.

Ibikoresho fatizo byo gukuramo zahabu mbere ibikoresho fatizo byo gukuramo zahabu ahanini byaturutse mu bucukuzi bwa zahabu, ubutare bwa zahabu bwacukuwe mu birombe bya zahabu, burimo n'ibindi byuma byagaciro.Nkuko twese tubizi, zahabu ikoreshwa cyane mubice bya elegitoroniki, imitako, bateri, firime yubuvuzi, insinga, nibindi.Ubu rero imyanda ya elegitoronike, imyanda yimitako irashobora kandi gutunganywa zahabu nibindi byuma byagaciro.Gutunganya zahabu ninzira yo gukuraho umwanda muri bullion cyangwa zahabu ivanze mubice kugirango ibicuruzwa bya zahabu byujuje ubuziranenge bwibicuruzwa bya zahabu.

Mugihe ukora ifu cyangwa flake, urashobora gukoresha imashini ikora ifu ya Hasung nicyuma gikora imashini mugutunganya zahabu.Nyuma yo gutunganya birangiye, koresha imashini ya zahabu ya Hasung kugirango ubone utubari twizahabu.
