Amakhemikhali Okukhipha Igolide eTanzania: Ama-Reagents e-CIL kanye ne-Heap Leaching

Izixazululo Ezihlanganisiwe Zokukhipha Igolide Zomkhakha Wezimayini waseTanzania

ITanzania iyizwe elinamandla amakhulu ekukhiqizweni kwegolide eMpumalanga Afrika, elisekelwe yizindawo zokugcina igolide ezisezingeni lomhlaba eLake Victoria Goldfield. Kusukela emisebenzini emikhulu yezentengiselwano ye-CIL/CIP eGeita naseBulyanhulu kuya kumaphrojekthi amakhulu okukhipha igolide esifundeni saseNorth Mara, ukukhulisa ukutholwa kwegolide ezinhlanganweni ezahlukahlukene ze-ore kudinga ukucubungula ama-reagents anekhwalithi engaguquki kanye nokuvumelana.

United Chemical sibambisana nabasebenzi bezimayini baseTanzania ukuze bathuthukise amasekethe abo okukhipha. Sihlinzeka ngeqoqo eliphelele lamakhemikhali ensimbi asezingeni eliphezulu, asekelwa yi-ocean shipment logistics eqondiswe ngqo esangweni eliyinhloko laseMpumalanga Afrika.

Ama-Reagent Ethu E-Flagship Emibuthanweni Yegolide YaseTanzania

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

Ezitshalweni ze-cyanidation ezisezingeni lezimboni ezidinga ukulawulwa okunembile kanye ne-aggressive leaching kinetics, sihlinzeka nge-AuCyan™ NaCN Sodium Cyanide ≥98.3% . Ngokuqinisekisa ubumsulwa obuyisisekelo obungu-≥98.3%, siqinisekisa ukuthi i-reagent yethu isebenza kahle kakhulu kunezinye izindlela ezijwayelekile zemakethe, ikhiqiza izinsalela ezincane ezinganyibiliki. Lokhu kuhlanzeka okuqinile kuvumela ochwepheshe bezinsimbi zezitshalo eTanzania ukuthi balondoloze i-alkalinity yokuvikela eqinile, banciphise ukusetshenziswa kwamakhemikhali jikelele, futhi bavale amazinga aphezulu okululama kuyo yonke imijikelezo yokukhiqiza eqhubekayo.

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

Ezitshalweni zanamuhla zokukhipha, ukucubungula ama-ore aqinile avela kuma-Greenstone Belts kudinga ukugaya okuqinile kanye nokushukunyiswa okukhulu kwemishini emathangini e-CIL/CIP. Ngaphansi kokucindezeleka okunjalo kokucheba, i-Carbon engaphansi iyaphuka, ithwale igolide elincibilikayo eliyigugu liye endaweni yokususa imfucuza. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon yenzelwe ukuvimbela lokhu. Inobulukhuni obuqinisekisiwe obuzimele be-ball-pan obungu- ≥ 99% , ukumelana kwayo okukhulu kokuncishiswa kuqinisekisa ukuthi igolide lakho lihlala lifakwe ngokuphephile kuyo yonke inqubo, liqinisekisa isivuno sakho sokugcina.

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

Ukuzulazula emasikweni echweba kanye nokuhamba kwangaphakathi kwezwe ukuze uthole izimpahla eziyingozi (DG) kungabangela izindleko ezinkulu zokuphatha kanye nokugcina. I-AuLeach™ Enobungani Nemvelo I-Gold Leaching Agent (GDA) inikeza enye indlela enamandla, engeyona ingozi. Isebenza njengendawo yokufaka ngqo esikhundleni se- cyanide yendabuko , le ndlela yokukhiqiza engeyona ingozi igcina i-kinetics yokukhipha enhle kakhulu ngenkathi idlula ngokuphelele imithethonqubo eqinile ye-DG emasikweni, okuvumela ukusulwa kwechweba okusheshayo kanye nokuphathwa okuphephile endaweni yemayini.

I-Strategic East African Logistics: Ichweba laseDar es Salaam

Ngokungafani nezizwe ezivalekile, iTanzania izuza ngqo engqalasizinda yayo enkulu yogu. United Chemical isebenzisa leli thuba lendawo ukuze ihlinzeke ngochungechunge lokuphakelwa olusebenza kahle kakhulu nolungabizi kakhulu enhliziyweni yeLake Victoria Goldfield.

Sinikeza ama-Incoterms aguquguqukayo, aphesheya kwezilwandle afanela izidingo zakho zokuthenga:

• I-FOB (Amachweba Amakhulu aseShayina): Siphatha yonke imithetho yokukhiqiza yasekhaya, ukukhishwa kwempahla kwamanye amazwe, kanye nokulayisha imikhumbi ephephile emachwebeni amakhulu aseShayina, sinikeza amadokhumenti aphelele ezentengiselwano kumhlinzeki wakho wezokuthutha oqokiwe.

• I-CIF (Ichweba laseDar es Salaam): Siphatha ukuthunyelwa kwempahla olwandle kanye nomshwalense ophelele wasolwandle ngqo echwebeni laseDar es Salaam , okuyisikhungo esiyinhloko sasolwandle eTanzania. Ukusuka lapho, abathumeli bendawo bangahambisa izimpahla kalula ngesitimela esiphakathi noma amanethiwekhi omgwaqo wesimanje baye ezikhungweni zokucubungula ezifundeni zaseMwanza naseShinyanga.

• Ukupakishwa Kwasolwandle Okuhambisana Ne-IMDG: Ukuqinisekisa ukuphepha kolwandle kanye nokuphuma kwechweba ngokushesha, i-AuCyan™ NaCN Sodium Cyanide ≥98.3% ipakishwe ngokuqinile ezigubhuni zensimbi eziqinisekiswe yi-UN noma emabhokisini ezinkuni aqinisiwe afakwe ezitsheni ezivaliwe, okuhambisana ngokugcwele namakhodi e-DG aphesheya kwezilwandle.

Umhlahlandlela Wokukhetha Ama-Reagent Emisebenzini YaseTanzania

imibuzo ejwayelekile ukubuzwa 

Q1: Iyiphi indlela yokuthumela esebenza kahle kakhulu United Chemical imikhiqizo eya ezimayini zaseTanzania?

Indlela ephumelela kakhulu ukusebenzisa imigomo yethu yokuthumela i-CIF ngqo echwebeni laseDar es Salaam . Njengesikhungo esikhulu saseMpumalanga Afrika, ixhunywe kahle eLake Victoria Goldfield ngamanethiwekhi esitimela nemigwaqo asunguliwe. Sihlinzeka ngayo yonke imibhalo edingekayo ehambisana ne-IMDG, okuvumela ama-ejenti akho okuhlanza endawo ukuthi acubungule imithwalo ngokushesha lapho kufika umkhumbi.

Umbuzo 2: Kungani ubumsulwa obuqinisekisiwe obungu-≥98.3% bubalulekile kwi -Sodium Cyanide?

Ukuhlanzeka okuqinisekisiwe okungu- ≥98.3% kusho ukuthi ikhemikhali igcwele kakhulu ukungcola okuncane. Lapho kucutshungulwa amazinga ahlukahlukene e-ore ezimayini zaseTanzania, lokhu kuhlanzeka okuphezulu kunciphisa ukusabela okungekuhle, kuzinzise indawo yokukhipha amanzi, futhi ekugcineni kunciphisa inani eliphelele le-reagent elidingekayo ngethani le-ore elicutshungulwayo, okwehlisa izindleko zokusebenza.

Umbuzo 3: I-AuLeach™ GDA izuzisa kanjani imisebenzi yokususa imithwalo eDar es Salaam?

Ukungenisa i-sodium cyanide yendabuko kusho ukubhekana nezinqubo eziqinile zeDangerous Goods (DG), okungaholela ezikhathini ezengeziwe zokubamba ichweba, izimali zokugcina impahla ezikhethekile, kanye nesidingo sezimvume zokuthutha eziyingozi. Ngenxa yokuthi i-AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) iyikhemikhali engenabungozi, igwema lezi zithiyo zomthetho, okuholela ekususweni kwezimpahla ngokushesha, izindleko zokuthutha eziphansi zangaphakathi, kanye nokuphepha kwendawo okuthuthukisiwe.
