Iikhemikhali zokuNciphisa iGolide eTanzania: IiReagents zeCIL kunye neHeap Leaching

Izisombululo zokuNcitshiswa kweGolide eziDibeneyo kwiCandelo leMigodi laseTanzania

ITanzania yeyona nto iphambili kwimveliso yegolide eMpuma Afrika, exhaswa ziintsalela zegolide ezikumgangatho wehlabathi zeLake Victoria Goldfield. Ukususela kwimisebenzi emikhulu yezorhwebo yeCIL/CIP eGeita naseBulyanhulu ukuya kwiiprojekthi ezinkulu zokukhupha igolide kwingingqi yaseNorth Mara, ukwandisa ukufunyanwa kwegolide kwiindawo ezahlukeneyo ze-ore kufuna ukucutshungulwa kwee-reagents zomgangatho ongapheliyo kunye nokuhambelana.

United Chemical Sisebenzisana nabaqhubi bemigodi baseTanzania ukuphucula iisekethe zabo zokukhupha. Sinikezela ngeseti epheleleyo yeekhemikhali zesinyithi ezikumgangatho ophezulu, ezixhaswa yi-logistics yokuthutha ulwandle elungelelanisiweyo ngqo kwisango eliphambili lolwandle laseMpuma Afrika.

IiReagents zethu zeFlagship zeeSekethe zeGolide zaseTanzania

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

Kwizityalo zokutshisa i-cyanidation ezikwizinga lemizi-mveliso ezifuna ulawulo oluchanekileyo kunye ne-aggressive leaching kinetics, sinikezela nge -AuCyan™ NaCN Sodium Cyanide ≥98.3% . Ngokuqinisekisa ubunyulu obusisiseko be-≥98.3%, siqinisekisa ukuba i-reagent yethu isebenza ngcono kunezinye iindlela zemarike eziqhelekileyo, ivelisa iintsalela ezincinci ezinganyibilikiyo. Olu bunyulu obuqinileyo luvumela iingcali ze-metallurgists eTanzania ukuba zigcine i-alkalinity yokukhusela ezinzileyo, zinciphise ukusetyenziswa kweekhemikhali ngokubanzi, kwaye zivale amazinga aphezulu okubuyisela kwimijikelo yemveliso eqhubekayo.

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

Kwizityalo zanamhlanje zokukhupha, ukucubungula i-ore eqinileyo evela kwiGreenstone Belts kufuna ukugaywa okuqinileyo kunye nokushukunyiswa okukhulu koomatshini kwiitanki zeCIL/CIP. Phantsi koxinzelelo olunjalo lokucheba, iCarbon ephantsi iyaphuka, ithwala igolide enyibilikayo exabisekileyo iye kwindawo yokutsala. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon yenzelwe ukuthintela oku. Inobunzima obuqinisekisiweyo obuzimeleyo be-ball-pan obuyi- ≥ 99% , ukumelana kwayo okugqithisileyo kokuncipha kuqinisekisa ukuba igolide yakho ihlala ifunxwe ngokukhuselekileyo kuyo yonke inkqubo, iqinisekisa isivuno sakho sokugqibela.

3. I-AuLeach™ I-Arhente yokuNciphisa iGolide enobuhlobo nokusingqongileyo (i-GDA)

Ukuhamba ngezithuthi zezibuko kunye nokuthutha impahla eyingozi (DG) ngaphakathi elizweni kunokubangela iindleko ezinkulu zolawulo kunye nokugcina. I-AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) inikezela ngenye indlela enamandla, engenabungozi. Isebenza njengendawo yokungena ngqo endaweni ye- cyanide yendabuko , le ndlela ingenabungozi igcina i-kinetics ebalaseleyo yokukhupha ngelixa idlula ngokupheleleyo imigaqo engqongqo ye-DG kwizithuthi zedolophu, ivumela ukususwa kwezibuko ngokukhawuleza kunye nokuphathwa ngokukhuselekileyo kwindawo yomgodi.

Uyilo lwezoBuchule lwaseMpuma Afrika: Izibuko laseDar es Salaam

Ngokungafaniyo nezizwe ezingangeni ndawo, iTanzania ixhamla ngokuthe ngqo kwiziseko zayo ezinkulu zonxweme. United Chemical isebenzisa eli thuba lendawo ukubonelela ngekhonkco lokubonelela elisebenza kakuhle nelingabizi kakhulu entliziyweni yeLake Victoria Goldfield.

Sinikezela nge-Incoterms eziguquguqukayo nezamazwe ngamazwe ezenzelwe iimfuno zakho zokuthenga:

• I-FOB (Izibuko Eziphambili zaseTshayina): Sijongana nayo yonke imithetho yokwenziwa kwemveliso yasekhaya, ukususwa kwempahla kwamanye amazwe, kunye nokulayisha iinqanawa ngokukhuselekileyo kumazibuko amakhulu aseTshayina, sinikezela ngamaxwebhu apheleleyo orhwebo kumboneleli wakho wezothutho otyunjiweyo.

• I-CIF (iZibuko laseDar es Salaam): Silawula ukuthunyelwa kwempahla elwandle kunye ne-inshurensi epheleleyo yolwandle ngqo kwiZibuko laseDar es Salaam , isixeko esiphambili saseTanzania. Ukusuka apho, abathumeli basekuhlaleni banokuthumela imithwalo ngaphandle kokuphazamiseka ngololiwe ophakathi okanye uthungelwano lwanamhlanje lweendlela ukuya kwizikhululo zokucubungula izinto kwimimandla yaseMwanza naseShinyanga.

• Ukupakishwa Kweenqanawa Ezihambelana Ne-IMDG: Ukuqinisekisa ukhuseleko lwaselwandle kunye nokuphuma ngokukhawuleza kwezibuko, i-AuCyan™ NaCN Sodium Cyanide ≥98.3% ipakishwe ngokungqongqo kwiidrama zentsimbi eziqinisekisiweyo yi-UN okanye kwiibhokisi zomthi eziqinisiweyo ezivalelwe kwizikhongozeli ezivaliweyo, zihambelana ngokupheleleyo neekhowudi ze-DG zamazwe ngamazwe.

Isikhokelo soKhetho lweeReagent kwimisebenzi yaseTanzania

Imibuzo ebuzwa qho 

Q1: Yeyiphi indlela yokuthumela ephumelelayo kakhulu United Chemical iimveliso eziya kwimigodi yaseTanzania?

Eyona ndlela isebenzayo kukusebenzisa imiqathango yethu yokuthumela i-CIF ngqo kwiZibuko laseDar es Salaam . Njengesixeko esikhulu saseMpuma Afrika, iqhagamshelwe kakuhle kwiLake Victoria Goldfield ngokusebenzisa uthungelwano lweendlela noololiwe olusekwe ngokwemigaqo ye-IMDG. Sinikezela ngazo zonke iimpepha ezifunekayo ezihambelana ne-IMDG, sivumela iiarhente zakho zokucoca ukuba zicubungule imithwalo ngokukhawuleza xa ifika enqanaweni.

Umbuzo 2: Kutheni kubalulekile ukuba ubumsulwa obuqinisekisiweyo obuyi-≥98.3% kwiSodium Cyanide?

Ubunyulu obuqinisekisiweyo be- ≥98.3% buthetha ukuba le khemikhali ixinene kakhulu kwaye ayinangcoliseko ingako. Xa kusetyenzwa amanqanaba e-ore ahlukeneyo kwimigodi yaseTanzania, obu bunyulu buphezulu bunciphisa iimpembelelo ezingalindelekanga, buzinzisa imeko yokuvuza, kwaye ekugqibeleni bunciphisa umthamo opheleleyo we-reagent efunekayo ngetoni nganye ye-ore esetyenziweyo, nto leyo enciphisa iindleko zokusebenza.

Umbuzo 3: I-AuLeach™ GDA inceda njani imisebenzi yokususa imithwalo eDar es Salaam?

Ukungenisa i-sodium cyanide yendabuko kuthetha ukujongana neenkqubo ezingqongqo zeDangerous Goods (DG), ezinokukhokelela kwixesha elandisiweyo lokubamba izibuko, iifizi ezikhethekileyo zokugcina impahla, kunye nesidingo seemvume zokuthutha ezinobungozi. Ngenxa yokuba i-AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) yikhemikhali engenabungozi, iyayiphepha le miqathango ilawulayo, nto leyo ekhokelela ekususweni ngokukhawuleza kwempahla yerhafu, iindleko zokuthutha eziphantsi ngaphakathi, kunye nokhuseleko oluphuculweyo lwendawo.
