Izixazululo Ezithuthukisiwe Zokukhipha Igolide Zomkhakha Wezimayini waseBurkina Faso

Izixazululo Ezithuthukisiwe Zokukhipha Igolide Zomkhakha Wezimayini waseBurkina Faso

IBurkina Faso isizisungule njengendawo ehamba phambili yokumba igolide eNtshonalanga Afrika, eqhutshwa yiBirimian Greenstone Belt echumayo. Kusukela emisebenzini emikhulu yezentengiselwano evulekile eHoundé nase-Essakane kuya kumaphrojekthi athuthuka ngokushesha angaphansi komhlaba, lesi sifunda sithembele kakhulu kumasekethe e-CIL (Carbon-in-Leach) kanye ne-CIP (Carbon-in-Pulp) asebenza kahle kakhulu.

Ukuze kukhuliswe ukubuyiswa kwegolide kuzo zombili izindawo ezi-oxidized kanye nama-sulfide ores ayinkimbinkimbi ajulile, opharetha badinga ama-reagent e-metallurgical aletha ubumsulwa obuqhubekayo kanye nokuzinza. United Chemical ungumlingani ozinikele womhlaba wonke wokuhlinzeka ngabakhiqizi begolide baseBurkina Faso, ohlinzeka ngephothifoliyo ephezulu yamakhemikhali okukhipha asekelwa yimigomo yokuthunyelwa kwamazwe ngamazwe ethembekile eyenzelwe izinto zokuthutha zaseNtshonalanga Afrika ezivaliwe.

Ama-Reagent Ethu E-Flagship Emibuthanweni Yegolide YaseBurkinabe

1. I-AuCyan™ NaCN Sodium Cyanide ≥98.3%

Isisekelo sokucubungula igolide lezimboni. Ezitshalweni ezinkulu ze-CIL/CIP ezidinga i-cyanidation enamandla futhi elawulwa kakhulu, sihlinzeka I-AuCyan™ NaCN Sodium Cyanide ≥98.3% . Yakhiwe ngaphansi kwezindinganiso ze-ISO eziqinile ukuze kuncishiswe ukungcola okungancibiliki, iqinisekisa ukuhamba kahle kokuncibilika. Lokhu kuvumela abaphathi bezitshalo ukuthi bathuthukise i-alkalinity evikelayo kanye nokulinganisa ama-reagent, banciphise ukusetshenziswa okuphelele ngenkathi bekhulisa isivuno sokugcina sokukhipha.

2. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon

Ezitshalweni zanamuhla zokukhipha, ukushukunyiswa komshini okunoboya obuphezulu kuyadingeka ukuze kugcinwe ukungcola kwensimbi kulenga. Kusebenza kalula I-Carbon izowohloka ngaphansi kwalezi zimo ezinzima, ithwale igolide elincibilikayo ngqo ezinsikeni. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon yakhelwe ngqo ukulwa nalokhu, inobulukhuni obuqinisekisiwe obuzimele be-ball-pan ≥ 99% Ukuqina kwayo okumangalisayo ngokomzimba kunciphisa ukubola, okuqinisekisa ukuthi igolide lakho lihlala limuncwa ngokuphephile ngemijikelezo eminingi yokucubungula.

3. I-AuLeach™ I-ejenti Yokuhlanzwa Kwegolide Enobungani Nemvelo (i-GDA)

Ukuthutha amakhemikhali anobuthi obukhulu ngaphesheya kwemingcele eNtshonalanga Afrika kuvame ukudinga izimvume eziningi zeDangerous Goods (DG) futhi, kwezinye izifunda, kudinga abaqaphi bezokuphepha abayinkimbinkimbi. I-AuLeach™ I-ejenti Yokuhlanzwa Kwegolide Enobungani Nemvelo (i-GDA) inikeza enye indlela ehlakaniphile nengeyona ingozi. Yakhelwe njengendawo yokungena eqondile esikhundleni sendlela yendabuko i-cyanide, i-AuLeach™ iyi-ejenti yokukhipha enobungani nemvelo, engenabo ubuthi obuncane. Igcina i-kinetics yokukhipha enhle kakhulu ngenkathi yenza kube lula kakhulu ukuthutha kwamanye amazwe, inciphise izindleko zokuthobela imithetho, futhi inikeze indawo yokusebenza ephephile yabasebenzi bezimboni.

Ukuthunyelwa Kwezinto Ezinobungcweti: Ukuhlinzeka NgeBurkina Faso Evaliwe

Ukusebenzisa imayini ezweni elivaliwe kusho ukuthi ukuthembeka kochungechunge lokuhlinzeka kubaluleke kakhulu njengekhwalithi yamakhemikhali. United Chemical isebenzisa amasango aseNtshonalanga Afrika asevele ekhona ukuze kuqinisekiswe ukuthi ama-reagent ayafika endaweni yakho ngaphandle kokuphazamiseka.

Sinikeza ama-Incoterms aguquguqukayo naqashelwa emhlabeni wonke ukuze avumelane nemodeli yakho yokuthenga:

• I-FOB (Amachweba Amakhulu aseShayina): Siphatha konke ukuthunyelwa kwempahla ngaphakathi ezweni, ukuthunyelwa kwempahla kwamanye amazwe, kanye nokuthunyelwa kwempahla ephephile emikhunjini emikhulu yaseShayina, sikunikeza amadokhumenti aphelele ozakwethu bezokuthutha obathandayo.

• I-CIF (Amachweba aseNtshonalanga Afrika):  Siphatha umshwalense wezimpahla zasolwandle kanye nowasolwandle ezindaweni ezibalulekile zokuhamba ezikhonza iBurkina Faso—ikakhulukazi i- Ichweba lase-Abidjan (Côte d'Ivoire) kanye Ichweba laseTema (eGhana) .

• Ukupakisha Okuhambisanayo Kokuhamba Kwangaphakathi: Uma usufikile echwebeni, umthwalo wakho kumele usinde ohambweni olude oluya ezweni. I-AuCyan™ NaCN Sodium Cyanide ≥98.3% ipakishwe ezigubhu zensimbi eziqinisekiswe yi-UN noma emabhokisini ezinkuni aqinisiwe (ahambisana ne-IMDG) ukuqinisekisa ukuphathwa okuphephile ngesikhathi sokuwela imingcele, kuyilapho izimpahla ezingeyona ingozi njenge I-AuLeach™ futhi I-AuCarb™ ziboshwe ezikhwameni ezinkulu ezisindayo.

Umhlahlandlela Wokukhetha Ama-Reagent Emisebenzini YaseBurkinabe

imibuzo ejwayelekile ukubuzwa 

Umbuzo 1: Yimiphi imizila yokuthumela engcono kakhulu yokulethwa United Chemical imikhiqizo eya eBurkina Faso?

Ngenxa yokuthi iBurkina Faso ivaliwe, sinikeza imigomo yokuthumela i-CIF emachwebeni amakhulu angomakhelwane, ikakhulukazi Ichweba lase-Abidjan (Côte d'Ivoire) futhi Ichweba laseTema (eGhana) Lapho sifika, sinikeza amadokhumenti aphelele okuphepha kwezentengiselwano kanye nezinto ezibonakalayo, okuvumela abathuthi bempahla yakho yendawo ukuthi bakhiphe izimpahla ngendlela ephumelelayo futhi bahlele ukuthutha amaloli ahamba ezweni ngqo endaweni yakho yemayini.

Umbuzo 2: Kungani i-AuLeach™ GDA iyisinqumo esihlakaniphile sokusebenza kwezimayini zaseBurkinabe?

Ukungenisa amakhemikhali anobuthi kakhulu njenge I-Sodium Cyanide kudinga izimvume zokuthutha eziqinile zeDangerous Goods (DG), ezokuthutha ezikhethekile, futhi ngezinye izikhathi abaphelezeli bezokuphepha besuka emachwebeni asogwini beya eBurkina Faso. I-AuLeach™ I-ejenti Yokuhlanzwa Kwegolide Enobungani Nemvelo (i-GDA) kuyindlela ehlukile engenangozi futhi enobuthi obuphansi. Inikeza ukusebenza okufanayo kokukhipha izimpahla ngenkathi idlula ngokuphelele imikhawulo yezokuthutha ye-DG, okwenza izinto zokuhamba ngaphesheya kwemingcele zisheshe, zishibhile, futhi ziphephe kakhudlwana.

UMBUZO 3: Kungani ubulukhuni bekhabhoni obungu-≥ 99% budingeka ekucubunguleni amatshe e-Birimian Greenstone?

Ama-ore avela eBirimian Greenstone Belt avame ukudinga ukugaya kahle kanye nokunyakaza okunamandla kwemishini kumasekethe e-CIL/CIP ukuze kutholakale kabusha kakhulu. Ikhabhoni Esebenzayo uma ingenawo amandla okusebenza, izophuka ibe uthuli olucolekile futhi ithwale igolide elifakwe emanzini iye endaweni yokuthunga. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon ivivinywa ukuze ibe lukhuni ≥ 99% , okunikeza ukuqina okungokomzimba okudingakalayo ukuze ugcine igolide lakho liphuma ngaphansi kwalezi zimo ezinzima.
