Izindlela ezi-4 eziphambili zokucubungula iGolide ukuze kuthuthukiswe iGolide

Isiphetho:Lo mhlahlandlela wobuchwepheshe ucacisa izayiphi ezine ezijwayelekile zokuthuthukiswa kogolide—Uhlukaniso Lwezinsiza, Ukugeja, I-Cyanidation (Ukuhweba), kanye Nezinhlelo Zokuhlanganisa.

Ukucubungula igolide yisinyathelo esiyinhloko esinqumayo ukusizakala kwegolide, izindleko zokusebenza, kanye nezinzuzo jikelele zephrojekthi. Ukukhetha indlela efanele yokucubungula igolide akuwona umgomo wezobuchwepheshe kuphela, kodwa futhi kuyikhethomali eyisisekelo ethinta ngqo ukusebenza kwesikhungo, ukuhambisana nemvelo, kanye nezinyanga ezide zokubuyisela.

Ezimayini, igolide ikakhulukazi ihlukaniswe kuma-3 izinhlobo: igolide eliphakeme (igolide lezinhlaka), igolide leplasa, kanye negolide elihlanganisiwe. Eziphumelelayo zokwakha, ama-gold ores ahluka kakhulu ekwakhekeni kwezimayini, usayizi wamaphuzu egolide, izinga lokuphola, kanye nokuhlangana nezinto ezingenamsebenzi. Njengoba kunjalo, ayikho indlela eyodwa yokuphatha ama-gold ores efanele yonke imidiya. Isixazululo esisebenzayo sokuthuthukiswa kwamagolide kufanele sihlinzekwe ngokusekelwe ezicini ze-ore, izinhloso zokukhiqiza, kanye nezimo zesayithi.

Lo mhlahlandlela wezobuchwepheshe uveza ukuqonda okubanzi kwezindlela eziyikhulu ezijwayelekile.izindlela zokuthuthukiswa kwensimbi yegolide—Ukwehlukaniswa kweMhlabeni, Ukuhamba Kwezimayini, iCyanidation (Ukuhlwanyela), kanye Nezinhlelo Zokuhlanganisa. Sihlaziya indlela ngayinye ngezindlela eziyisihlanu ezibalulekile—umgomo, izinhlobo zamaminerali ezifanele, inqubo eyinhloko, imishini eyinhloko, kanye nezici zenqubo—sinikeza isakhiwo esicacile nolwazi oluyisisekelo kokubili abaqalayo nabachwepheshe bezimboni.

1. Indlela Yokuhlukanisa NgokweGravity

Isimiso:Njengomunye wezindlela zokuqala nezishibhile zokucubungula igolide, ukuhlukaniswa kwegrava kusebenzisa umehluko wesisindo phakathi kwegolide namaminerali angafaneleki ukuze kufinyelelwe ekuhlukanisweni ngaphandle kwemithi yokwandisa.

Izinhlobo ze-Ore ezisebenzayo:Ikakhulu ifaneleke kuma-placer gold deposits, kanye namamabhande egolide lapho amaqhugwane egolide enziwa kube kuhlangene futhi akhanya ngendlela engafani (isb., amabhande e-quartz anegolide).

Inqubo Eyisisekelo Yokugeleza:

• Ukuqweqwa kanye nokuhlolwa kwezimbobo zezimayini.
• Ukuhlukaniswa nokukhishwa kwensalela
• Ukugxila komphakathi usebenzisa ama-jigs, amatafula ashukumisayo, izipele zebhande, noma abakhweli bezithuthuki.
• Ukukhishwa kwe-concentrate yemaminerali anheavy

Ezimbonini eziningi zokuhlunga igolide, ukuhlukaniswa kwesikhumbuzo kuhlanganiswe emjikelezweni wokugcotshwa ukuze kutholwe igolide elikhululekile elinobukhulu obukhulu kungakapheli isikhathi eside.

Izinto Eziyinhloko:I-Jaw Crusher, I-Cone Crusher, I-Jig, I-Shaking Table, I-Spiral Chute, I-Centrifugal Concentrator. Lezi zingasetshenziswa ngabodwa noma zixhunywe ndawonye.

Izimpawu Zokusebenza:

• Izinzuzo: Inqubo elula, izindleko eziphansi, akukho ukungcoliswa kwezemvelo, kanye nokusebenza kahle kakhulu ekubuyiseni igolide elikhulu.
• Imikhawulo: Ukubuyiselwa okuphansi kwezinhlayiya zegolide ezincane nezincane kakhulu.
• Uhlelo Olujwayelekile: Ngokuvamile lusebenza njengesinyathelo sokucindezela ngaphambi kokuhlangana, noma ekuqhelaniseni kwensimbi yegolide.

2. Indlela Yokuflothi

Isimiso:Isebenzisa umehluko ezakhiweni zolwandle lwezinsiza zegolide (ikakhulukazi igolide elihambisana ne-sulfides). Ngokuqhuba izithasiselo, insiza ezihlosiwe yenziwa ukuba ixhume kumabhakabhaka omoya futhi ihlale, ifinyelela ekuhlukaniseni nasemncintiswaneni.

Izinhlobo ze-Ore ezisebenzayo:Ikakhulukazi ihlola izinsiza zegolide ezikhona emaphashini lapho igolide ixhunywe edlondlobala (efana ne-pyrite, chalcopyrite), kanye nezinsiza ezinegolide ezahlukene ze-sulfide.

Inqubo Eyisisekelo Yokugeleza:

• Ukuqhumisa nokuhlola okwenziwa ngezinyathelo eziningi kwezimbaqanga ezivela emigodleni.
• Ukwenza imihlaba eluhlaza
• Ukulawulwa kwepulp & Ukwengeza kwe-Reagent (abakhiqizi, abavuthayo)
• Ukuhlukaniswa KweFlotation (Izigaba Zokuhlukanisa, Zokuhlanza, Zokubamba)
• Ukukhiqiza i-Sulfide Concentrate enegolide (idinga ukusebenza okwengeziwe ukuze kutholakale igolide yokugcina).

Imishini Eyinhloko: I-Jaw Crusher, I-Cone Crusher, I-Ball Mill, I-Mechanical Agitation Flotation Cell (eyaziwa kakhulu), I-Flotation Column (ifanele ukuhlukaniswa kwezinhlayiya ezincane).

Izimpawu Zokusebenza:

• Izinzuzo: Umphumela omuhle wokugxila nokubuyiselwa okuphezulu kwegolde elincane, kuvumela ukubuyiselwa okuyinhlanganisela kwemithi eminingi.
• Imikhawulo: Ayikwazi ukukhiqiza ngokusobala umkhiqizo wokugcina wegolide.
• Uhlelo Olujwayelekile: Imvamisa iyunithi eyisisekelo ezinqubweni zohlanganyelo ezifana ne-Flotation-Cyanidation, noma isetshenziselwa ngokuzimela ekwahlukaniseni izinsalela ze-sulfide ezilula.

3. Indlela yeCyanidation (Ukuhluza)

Isimiso:Endaweni ethile enokhahlo, enegesi, isixazululo se-cyanide sithambisa igolide ukuze sibe nomsebenzi wegolide-cyanide. Igolide emva kwalokho ibuyiswa ngokumunca noma ngokufuduka, ivumela ukukhiqizwa okuqondile kwegolide kokugcina.

Izinhlobo ze-Ore ezisebenzayo:Imayini enezinga eliphakeme lokushwabana kanye negolide elitholakala kahle, elinokungcoliswa okuncane noma okungekho njengensimbi ephakathi noma i-arsenic okuthinta ukungena kwe-cyanide.

Inqubo Eyisisekelo Yokugeleza:

Izindlela ezimbili eziyinhloko zikhona:

① Ukucibilikisa i-Ore ngensipho: I-Ore iyaphukula kahle ukuya kokuqashelwa → Ukwehla kwe-Cyanide → Ukuhweziswa/Ukudluliselwa → Ukukhishwa & Ukuhlela kwe-Electrolysis → Ukuhluza kube igolide.

② Ukugxila kwe-Cyanidation: Kuphela ukugxila kokuphakama okwenziwa kabusha ngaphambi kokuba kudlule kulokhu okukhishwa phezulu, okwenza kube kuphumelela ngaphezu kwamandla.

Izinsiza Eziyinhloko: I-Jaw Crusher, I-Cone Crusher, Ama-High-Pressure Grinding Rolls (HPGR), I-Ball Mill, Amathangi Okukhanyisa, Ama-Adsorption Columns, I-Elution & Electrolysis Unit, I-Merrill-Crowe Zinc Precipitation Box. Izinsiza eziyisisekelo ziqinisekisa ukusebenza okuhle nokuzinzile.

Izimpawu Zokusebenza:

• Izinzuzo: Izinga eliphezulu lokuphuma, ubuchwepheshe obumalungelo, ukukhiqizwa kwegolide ngqo.
• Izinkinga: Ukuphazamiseka okuphezulu kwe-cyanide, kudinga ukulawulwa kwezokusebenza kwemvelo nokuphepha okuqinile.
• Ithongo Elizayo: Gxila ekuphakamiseni izithasiselo zokukhupha igolide ezine-toxicity ephansi/ ezingeyona i-cyanide.

4. Ukuhlolwa Kokucubungula Izinsiza Zegolide Ehlanganisiwe

Kwemigudu ye-gold eyinkimbinkimbi, edinga umsebenzi onzima, inqubo eyodwa ivamise ukuba yincane ukuze kuzuze kahle. Ukuhlanganisa izinqubo kukhulisa noma iyiphi inani lokubuyiselwa kanye nezinzuzo zezemali. Ukuhlanganiswa okubili okujwayelekile kuyavame.

(I) Inqubo ehlanganisa i-Gravity-Flotation

Umgomo & Ukusebenza:Ukuhlukaniswa kwe-gravity kubuyisela igolide elikhulu, kanti i-flotation ibuyisela igolide elincane kanye negolide kumaminerali e-sulfide ahlukaniswe nge-gravity. Lokhu kulungiselelwe ama-ores ayinkimbinkimbi anegolide ethokozisayo engakwazi ukuhlukaniswa ngezilinganiso ezihlukahlukene.

Inqubo Eyisisekelo Yokugeleza:Ukuphahlazeka kwensimbi & Ukuhlola → Ukwehlukaniswa kokukhanya (ukuphuma kwegolide okukhulu) → Ukugaya okuhle kwe-tailing → Ukuflotation (ukuphuma kwegolide okuhle) → Lezi zimbili zokugxila zithathwa ngokwehlukana ukuze zibe negolide yokugcina.

Izici:Kuphephula igolide elikhulu nelincane, kuhlinzeka ngesibalo esiphezulu sokuphuma kanye nokugeleza okuguquguqukayo, ngokutshalwa kwemali okuphakeme kancane kodwa kwezezimali okuhle kakhulu.

(Ii) Inqubo ehlanganisa i-Flotation ne-Cyanidation

Umgomo & Ukusebenza:Ukudonsa kuqala kwandisa igolide kube yisixube, esicutshungulwa ngokuqandisiwe. Lokhu kufanelekile kuma-ores ayinkimbinkimbi lapho igolide ikakhulu itholakala kwi-sulfides futhi kuyinqubo ejwayelekile embonini.

Inqubo Eyisisekelo Yokugeleza:Ukuqhumisa & Ukugaya Kwe-ore → Ukuhlangana (ukukhiqizwa kokugxiliselwa kwegolide) → Ukuqoqwa Kwezinto (ukuthuthukiswa kokukhululwa) → Ukuhlwanyela i-Cyanidation & Ukukhishwa Kwegolide → Ukulahla ama-tailings; Uma ukugxiliselwa kubandakanya ukungcola okuphazamisayo, kungadingeka ukwelashwa kwangaphambi kokuphuma njengokushisa.

Izici:I-High comprehensive recovery rate, yehlisa ukusetshenziswa kwe-cyanide nengcindezi yemvelo, ilungele ama-ore e-sulfide aphikisanayo anzima. Kuhilela ukutshalwa kwezimali okuphezulu kwezinqubo nezinsiza kodwa kunikeza ukusebenza kokubuyisela okuzinzile.

Le mapheshana iyenye yezixazululo ezamukelwa kakhulu zokuthuthukisa igolide emashoneni wokucubungula igolide akhona namuhla.

Indlela yokukhetha isixazululo esifanele sokucubungula i-gold ore

Ukukhetha indlela efanele yokucubungula ithambo legolide kudinga ukuhlolwa okuhlelekile kwe:

• Uhlobo lwezathululo zegolide kanye nesakhiwo sambalai.
• Usayizi wezinto zhegazi kanye nezici zokukhululwa
• Iziqondiso zokushintsha umoya kanye nezingxenye ezingcolile
