Amakuru

1. Gutandukanya aside nitrike kugira ngo hakorwe zahabu, gutandukanya aside nitrike bishobora gukoreshwa, gukurura aside nitrike mu byuma, gukenera gukuramo zahabu mu byuma mu byuma. Hanyuma Beaker ishyirwa ku gikoresho cyo kubikamo ifuru hanyuma igashyushya itara rya alukolo kugira ngo ikore zahabu yoroheje.

2. Gutandukanya aqua regia uretse gukuramo zahabu, hakoreshwa gutandukanya aqua regia. Nyuma yo kuvanga igice kimwe cya aside nitrike n'ibice bitatu bya aside hydrochloric muri aqua regia, ibyuma bigomba gukurwamo bishyirwa muri aqua regia hanyuma bigashungurwa nyuma y'uko icyuma kirangiye. Hanyuma birashyuha hanyuma bigasimbuzwa impapuro z'umuringa, zishobora no gukurwamo zahabu.

3. Uburyo bwo gutandukanya H2SO4 buvanga H2SO4 na H2O4 mu gipimo cya kimwe kuri kimwe, hanyuma bugashyira ikoranabuhanga rikenewe kugira ngo ritunganywe mu gisubizo cya H2O4, hanyuma bugategereza ko icyuma kirangira, ikintu cy'umuhondo cy'icyuma ni zahabu.

Ibikoresho fatizo byo gucukura zahabu mbere ibikoresho fatizo byo gucukura zahabu ahanini byaturukaga mu mabuye y'agaciro ya zahabu, amabuye y'agaciro acukurwa mu birombe bya zahabu, kandi arimo andi mabuye y'agaciro. Nkuko twese tubizi, zahabu ikoreshwa cyane mu bikoresho by'ikoranabuhanga, imitako, bateri, filimi z'ubuvuzi, insinga, nibindi. Ubu rero imyanda ya elegitoroniki, imyanda y'imitako ishobora no kuba zahabu itunganyijwe n'andi mabuye y'agaciro. Gutunganya zahabu ni inzira yo gukuraho imyanda muri bullion cyangwa zahabu ivanze mu byiciro kugira ngo ibicuruzwa bya zahabu bihuze n'ibisabwa mu bucuruzi bwa zahabu.

Mu gihe ukora ifu cyangwa uduce duto, ushobora gukoresha imashini ikora ifu y'icyuma ya Hasung n'imashini ikora uduce duto tw'icyuma kugira ngo utunganye zahabu. Nyuma yo kuyitunganya, koresha imashini ikora uduce duto twa zahabu ya Hasung kugira ngo ubone uduce duto twa zahabu turabagirana.
