Uruhare rwa nitrate ya sisitemu mu gucukura amabuye y'agaciro ya zahabu

Icyondo cyanide cyuzuye ni uburyo bwa kera kandi bwizewe bwo kuvoma zahabu, bukoreshwa cyane mubikorwa muri iki gihe.Mu myaka yashize, mu rwego rwo kongera umusaruro wa zahabu, kumenya umusaruro wa zahabu ku rubuga, no kongera umusaruro w’inganda, ibirombe bitandukanye bya zahabu byaguye uburyo bwo gukoresha ibyondo bya cyanide byuzuye.

Ibice bya zahabu byinjijwe mu bucukuzi butandukanye ahanini ni zahabu yo hagati kandi inoze neza, kandi uko zahabu ibaho ni zahabu hagati y'izahabu na zahabu.Iyi leta yashyizwemo ifasha icyondo cyanide cyuzuye, ariko haracyariho uduce duto duto twiziritse muri zahabu mu bucukuzi butandukanye, bizagira ingaruka runaka ku gipimo cya zahabu.Ibyavuye mu bushakashatsi bw’amabuye y'agaciro byerekana ko buri bwoko bw'amabuye y'agaciro ari ubutare bwa zahabu bugoye guterwa, kandi cyanide nyinshi ikoreshwa mu gihe cya cyanide, ibyo bikaba bigira ingaruka ku gipimo cya zahabu.
Ubusanzwe ibyondo byose byangiza cyanide ntibikoresha gusa cyanide nyinshi, ariko kandi bifite umuvuduko muke wo gucukura amabuye y'agaciro ya zahabu yo hagati na sulfide arimo imyanda myinshi yangiza nkumuringa, arsenic, na sulferi.Ongeramo nitrate ya nitrate yo kwitegura mbere yo kumeneka irashobora kugabanya igihombo cya cyanide kandi ikongera umuvuduko.
Ongeramo nitrate ya sisitemu mbere yo kumeneka irashobora kugabanya ibirimo ibyuma byangirika byicyuma, bityo bikagabanya ikoreshwa rya sodium cyanide.Mu birombe bya zahabu, fata urugero rwamabuye yo mu bwoko bwa pyrrhotite yo mu bwoko bwa zahabu-2-umuringa.Ibiri muri pyrrotite bigera kuri 23130%.Mu miterere ya molekulire ya pyrrotite, hari atome ya sulfure ihujwe cyane na okiside byoroshye kugirango ibe sulfide ikemuka, ikoresha cyanide nyinshi mugihe cyanide yangiza kandi ikongerera igihe cyo kwitegura.Kwiyongera kwa nitrate ya nitrate irashobora kugabanya kuba ioni sulfide ihumeka hamwe na sulfide ikemuka, bityo bikagabanya ikoreshwa rya sodium cyanide no kuzamura umuvuduko.
