Flotation Theory ya Zahabu Ore

Flotation Theory ya Zahabu Ore

Zahabu ikunze gukorwa muburyo bwubuntu mu bucukuzi.Amabuye y'agaciro akunze kugaragara ni zahabu isanzwe na feza-zahabu.Bose bafite kureremba neza, flotation rero nimwe muburyo bwingenzi bwo gutunganya amabuye ya zahabu.Zahabu ikunze guhuzwa namabuye menshi ya sulfide.Symbiotic, cyane cyane symbiotic hamwe na pyrite, bityo guhinduranya zahabu no guhinduranya amabuye y'agaciro ya sulfide nka pyrite yitwa zahabu bifitanye isano rya bugufi mubikorwa.Imyitozo ya flotation yibitekerezo byinshi tuzabimenyesha hepfo ni amabuye ya zahabu aho zahabu na sulfide zibana.

Ukurikije ubwoko nubunini bwa sulfide, amahitamo akurikira arashobora guhitamo.
① Iyo sulfide iri mu bucukuzi iba pyrite, kandi ntayindi sulfide iremereye, kandi zahabu iba mubice bito kandi byiza na symbiotic hamwe na sulfide y'icyuma.Amabuye y'agaciro asimburwa kugira ngo atange umusaruro wa zahabu ya sulfide, kandi flotation yibanda ku kirere nyuma yo gutwarwa n’ikirere, bityo bikirinda kuvura cyanidation y’amabuye yose.Imyitozo ya flotation irashobora kandi koherezwa muruganda rwa pyrometallurgie kugirango rutunganyirizwe.Iyo zahabu iba muburyo bwa subicroscopique nuduce twa pyrite, ingaruka ya cyanide itaziguye yibitekerezo ntabwo iba nziza, kandi igomba gutwikwa kugirango itandukane ibice bya zahabu hanyuma ikarekurwa nikirere.

② Iyo sulfide iri mu bucukuzi bw'amabuye irimo chalcopyrite, sphalerite, na galena usibye sulfide y'icyuma, zahabu iba ari symbiotic hamwe na pyrite hamwe na sulfide y'ibyuma biremereye.Gahunda rusange yo kuvura: Ukurikije uburyo busanzwe hamwe na sisitemu ya chimique yubutare bwa sulfide idafite ferrous, fata kandi uhitemo intumbero ihuye.Imyitozo yoherejwe kuri smelter kugirango itunganyirizwe.Zahabu yinjira mu muringa cyangwa isasu (ubusanzwe umuringa mwinshi cyane) kandi igarurwa mugihe cyo gushonga.Igice cya zahabu na fer sulfide ni symbiotic irashobora guhindurwa kugirango ibone icyuma cya sulfide cyuma, gishobora kugarurwa hifashishijwe gutwika no guhumeka ikirere.

③ Iyo hari sulfide yangiza ikirere mu bucukuzi bw'amabuye y'agaciro, nka arsenic, antimony, na sulfide ya sulfide, konside ya sulfide yabonetse na flotation igomba gutwikwa kugirango itwike arsenic, sulfide nibindi byuma muri concentrate kugirango byoroshye Kubyuka byoroshye bya okiside yicyuma ihindagurika , gusya nanone kandi ukoreshe ikaramu kugirango ukureho okiside yicyuma ihindagurika.

④ Iyo igice cya zahabu mu bucukuzi kibaho mu bwisanzure, igice cya zahabu ni symbiotic hamwe na sulfide, naho igice cya zahabu kikaba cyaratewe mu mabuye y'agaciro ya gangue.Amabuye y'agaciro agomba kugarurwa hamwe no gutandukanya imbaraga kugirango agarure zahabu yubuntu, kandi agarure symbiose hamwe na sulfide binyuze muri flotation Kuri zahabu, bitewe nibiri muri zahabu yibirindiro bya flotation, birakenewe ko harebwa niba wakoresha imiti yimiti.Imyitozo ya flotation irashobora kuba hasi neza hanyuma ikarekurwa neza, cyangwa ibisigazwa byahiye birashobora kuba hasi neza nyuma yo gutwikwa hanyuma bikarekurwa.
