Ukusetshenziswa kanye nezinzuzo zama-reagents kunqubo ye-Gold Mine Cyanidation

I-cyanidation yezimayini zegolide iyindlela evame ukusetshenziswa ekufakweni kwe-ore yegolide, esetshenziswa kabanzi ngenxa yokusebenza kwayo kahle kanye nezici zayo zezomnotho. Lesi sihloko sizokunikeza isingeniso esiningiliziwe sokusetshenziswa kwe-reagent kanye nezinzuzo zayo enqubweni ye -cyanidation yezimayini zegolide , okuzokusiza ukuthi uqonde kangcono lobu buchwepheshe bokufakwa kwe-ore.

I. Uhlolojikelele lweCyanidation

I-Cyanidation iyindlela yokugqoka i-ore ekhipha igolide kuma-ore ngesisombululo se -cyanide . Ngokwezakhiwo ze-ore kanye nezidingo zokugqoka i-ore, i-cyanidation ingahlukaniswa ngezigaba ezimbili ezinkulu: i-Agitation cyanidation kanye ne-Percolation cyanidation . I-Agitation cyanidation isetshenziswa kakhulu ekwelapheni ama-flotation gold concentrate noma konke - i-slime cyanidation, kuyilapho i-percolation cyanidation isetshenziswa kakhulu ekwelapheni ama-ore aphethe igolide eli-oxidized eliphansi.

II. Ukusetshenziswa kwe-sodium cyanide

I-Sodium cyanide ingenye yama-reagent asetshenziswa kakhulu enqubweni ye-cyanidation. Umsebenzi wayo oyinhloko ukuncibilikisa igolide esixazululweni se-cyanide ukuze kwakheke igolide elincibilikayo - ama-cyanide complexes. Ukusetshenziswa kwe -Sodium cyanide kulula futhi kuyasebenza. Kodwa-ke, ubuthi bayo nezinkinga zokungcola kwemvelo azinakwa. Ukuze kuxazululwe lokhu, i-Xinhai Mining Technology Co., Ltd. ithuthukise i-ejenti yokugqoka i-ore yegolide enobungani nemvelo ukuze ithathe indawo ye-Sodium Cyanide ekukhishweni kwegolide kwe-cyanide. Le ejenti yokugqoka i-ore ayinayo nje kuphela indlela efanayo yokusebenzisa njenge -sodium cyanide , kodwa futhi inezinga lokululama okusheshayo, izinga eliphezulu lokuphuma, kanye nezindleko eziphansi.

III. Isicelo se-Reagent ku-Agitation Cyanidation

Inqubo yegolide yokukhipha i-cyanidation enyakazayo ihlanganisa ikakhulukazi izinhlobo ezimbili zamashidi agelezayo: eyodwa ikhawunta eqhubekayo - ukuwashwa kwamanje, kanye nenqubo ye-cyanidation - zinc replacement (indlela ye-CCD kanye nendlela ye-CCF) yokubuyisela igolide ngokufaka esikhundleni kanye nemvula nge-zinc powder (intambo); enye isihlungi - i-cyanide carbon yamahhala - in - pulp inqubo (indlela ye-CIP kanye nendlela ye-CIL) ekhangisa ngokuqondile futhi ibuyise igolide ku-pulp ye-cyanide isebenzisa ikhabhoni ecushiwe ngaphandle kokuhlunga nokuwashwa. Kulezi zinqubo, i-sodium cyanide noma i-ejenti yokugqoka i-ore yegolide evumelana nemvelo iyona eyisisebenzi esibalulekile. Ngaphezu kwalokho, ama-reagents asizayo afana ne-zinc powder kanye ne-carbon activated nawo ayadingeka.

IV. Isicelo se-Reagent ku-Percolation Cyanidation

I-Percolation cyanidation ifanele idiphozithi yendawo kanye nezinto ezixegayo nezinezimbotshana. Izinqubo ezijwayelekile zihlanganisa ukucwiliswa kwethangi nokucwiliswa kwenqwaba. Indlela ye-heap leaching inezindleko eziphansi zokukhiqiza, ingaba nezikali ezihlukahlukene, futhi inokuvumelana nezimo okuqinile. Phakathi nenqubo yokucwilisa inqwaba, isixazululo se-cyanide leaching sikhipha igolide etsheni ngokufafaza noma ngokubhobozwa. Isixazululo se-leaching sigaywa kabusha izikhathi eziningi futhi sifuthwe enqwabeni yensimbi ngokuphindaphindiwe. Khona-ke, isixazululo se-leaching siyaqoqwa futhi siphathwe nge-ion - exchange resin, i-activated carbon adsorption, noma i-zinc powder (wire) esikhundleni. I-sodium cyanide noma i-ejenti yokugqoka i-ore yegolide evumelana nemvelo idlala indima ebalulekile kule nqubo.

V. Izinzuzo zama-ejenti okugqoka ama-Ore Angenani Imvelo

Ngenxa yezingqinamba ze-sodium cyanide kanye nezidingo zemvelo zamanje, i-Xinhai Mining Technology Co., Ltd. ithuthukise ngempumelelo i-ejenti yokugqoka igolide yegolide evumelana nemvelo. Le agent yokugqoka i-ore ayikwazi ukufaka esikhundleni se-sodium cyanide kuphela, kodwa futhi inezinzuzo ezilandelayo:

1. Ukululama okusheshayo : I-ejenti yokugqoka i-ore enobungani nemvelo inesivinini esisheshayo sokukhipha igolide ku-ore ngesikhathi esifushane futhi ithuthukise ukusebenza kahle kokukhiqiza.

2. Izinga lokuphuma kwamanzi eliphakeme : Izinga lokuphuma kwamanzi le-ore dressing agent enobungani nemvelo liphakeme kunele-sodium cyanide yendabuko, engabuyisa igolide ku-ore ngokugcwele futhi ithuthukise ukusetshenziswa kwemithombo.

3. Izindleko eziphansi : Izindleko zokusebenzisa i-ore dressing agent enobungani nemvelo ziphansi kuneze-sodium cyanide, ezinganciphisa ngempumelelo izindleko zokukhiqiza futhi zithuthukise izinzuzo zomnotho.

4. Inobungani nemvelo futhi ayinangcolisi : I-ore dressing ewusizo nemvelo ayinabo ubuthi futhi ayinangozi, inobungani nemvelo, ihlangabezana nezidingo zamanje zemvelo, futhi inciphisa ukungcola kwemvelo.

VI. Isiphetho

Ukusetshenziswa kwe-reagent kunqubo ye-cyanidation yemayini yegolide kuyisixhumanisi esibalulekile kubuchwepheshe bokugqoka i-ore. I-sodium cyanide kanye ne-ejenti yokugqoka i-ore yegolide evumelana nemvelo idlala indima ebalulekile ezinqubweni ezahlukene ze-cyanidation. Ngokuqhubeka okuqhubekayo kwezobuchwepheshe kanye nokugxila okwandayo ekuvikelweni kwemvelo, ukuthuthukiswa kanye nokusetshenziswa kwama-reagents asebenza kahle kakhulu futhi angavumelani nemvelo kuzoba isiqondiso esibalulekile ekuthuthukisweni kwesikhathi esizayo kwemboni yezimayini zegolide.
