Izisombululo zeCIL kunye neLeaching eziSebenza ngokuPhezulu kwiMigodi yeGolide yaseBurkina Faso

Izisombululo zeGolide eziPhambili kwiCandelo leMigodi laseBurkina Faso

IBurkina Faso izibonakalise njengendawo ephambili yokumba igolide eNtshona Afrika, iqhutywa yiBirimian Greenstone Belt echumayo. Ukusuka kwimisebenzi emikhulu yorhwebo evulekileyo eHoundé nase-Essakane ukuya kwiiprojekthi ezikhula ngokukhawuleza phantsi komhlaba, lo mmandla uxhomekeke kakhulu kwiisekethe ze-CIL (Carbon-in-Leach) kunye ne-CIP (Carbon-in-Pulp) ezinefuthe eliphezulu.

Ukuze kuphuculwe ukufunyanwa kwegolide kwiindawo ezixilisweyo kunye nee-sulfide ores ezinzulu, abaqhubi bafuna ii-reagents ze-metallurgical ezinika ubunyulu kunye nozinzo oluhambelanayo. United Chemical liqabane elizinikeleyo kwihlabathi liphela kubavelisi begolide baseBurkina Faso, linikezela ngepotifoliyo yexabiso eliphezulu yeekhemikhali zokukhupha ezixhaswa yimigaqo yokuthunyelwa kwempahla yamazwe ngamazwe ethembekileyo eyenzelwe uthutho olungena kwiNtshona Afrika.

IiReagents zethu zeFlagship zeBurkinabe Gold Circuits

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

Isiseko sokwenziwa kwegolide kwimizi-mveliso. Kwizityalo ezinkulu zeCIL/CIP ezifuna i-cyanidation enamandla nelawulwa kakhulu, sinikezela nge -AuCyan™ NaCN Sodium Cyanide ≥98.3% . Yenziwe phantsi kwemigangatho ye-ISO eqinileyo yokunciphisa ukungcola okunganyibilikiyo, iqinisekisa i-kinetics yokunyibilika okuzinzileyo. Oku kuvumela abaphathi bezityalo ukuba baphucule i-alkalinity yokukhusela kunye ne-reagent dosing, benciphisa ukusetyenziswa ngokubanzi ngelixa bekhulisa isivuno sokugqibela sokukhutshelwa.

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

Kwizityalo zanamhlanje zokukhupha, ukushukunyiswa koomatshini okucociweyo kakhulu kuyimfuneko ukugcina amatshe esinyithi emile. I-Carbon ethambileyo esebenzayo iya konakala phantsi kwezi meko zinzima, ithwale igolide enyibilikayo ngqo kwiintsalela. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon yenzelwe ngokukodwa ukulwa noku, inobunzima obuqinisekisiweyo obuyi- ≥ 99% . Ukuqina kwayo okumangalisayo kunciphisa ukuguguleka, iqinisekisa ukuba igolide yakho ihlala ifunxwa ngokukhuselekileyo kwimijikelo emininzi yokucubungula.

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

Ukuthutha iikhemikhali ezinobungozi kakhulu ngaphaya kwemida eNtshona Afrika kudla ngokufuna iimvume ezininzi zeDangerous Goods (DG) kwaye, kwezinye iindawo, abantu abakhuselekileyo abanzima. I-AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) ibonelela ngenye indlela enobuchule, engenabungozi. Yenzelwe njengendawo yokungena ngqo endaweni ye- cyanide yendabuko , i-AuLeach™ yiarhente yokukhupha enobuhlobo nokusingqongileyo, enobuhlobo nokusingqongileyo. Igcina i-kinetics egqwesileyo yokukhupha ngelixa inciphisa kakhulu ukuhanjiswa kwempahla, inciphisa iindleko zokuthobela imithetho, kwaye ibonelela ngendawo yokusebenza ekhuselekileyo kubasebenzi bezityalo.

Uyilo lwezoBuchule: Ukubonelela ngeBurkina Faso evaliweyo

Ukusebenza kwemigodi kwilizwe elingangeniswanga manzi kuthetha ukuba ukuthembeka kwekhonkco lokubonelela ngempahla kubaluleke kakhulu njengomgangatho weekhemikhali. United Chemical isebenzisa amasango aseNtshona Afrika aselwandle asele emiselwe ukuqinisekisa ukuhamba okungapheliyo kwee-reagents kwindawo yakho.

Sinikezela ngee-Incoterms eziguquguqukayo neziqatshelwa kwihlabathi liphela ukuze zihambelane nemodeli yakho yokuthenga:

• I-FOB (Izibuko Eziphambili zaseTshayina): Silawula zonke izinto ezithunyelwayo zasekhaya, ukususwa kwempahla kwamanye amazwe, kunye nokulayisha iinqanawa ngokukhuselekileyo kwiindawo ezinkulu zaseTshayina, sikunika amaxwebhu apheleleyo amaqabane akho othutho akhethwayo.

• I-CIF (Izibuko zaseNtshona Afrika): Sijongana ne-inshurensi yokuthutha impahla elwandle kunye neyolwandle kwiindawo ezibalulekileyo zokuthutha ezikhonza iBurkina Faso—ngakumbi iPort of Abidjan (eCôte d'Ivoire) kunye nePort of Tema (eGhana).

• Ukupakisha Okuhambelanayo Nokuhamba Ngaphakathi: Wakufika echwebeni, umthwalo wakho kufuneka uhlale uphila uhambo olude emhlabeni. I-AuCyan™ NaCN Sodium Cyanide ≥98.3% ipakishwe kwiidrama zentsimbi eziqinisekisiweyo yi-UN okanye kwiibhokisi zomthi eziqinisiweyo (ezihambelana ne-IMDG) ukuqinisekisa ukuphathwa ngokukhuselekileyo ngexesha lokuwela imida, ngelixa iimpahla ezingengobungozi ezifana ne -AuLeach™ kunye ne-AuCarb™ zigcinwe kwiingxowa ezinkulu.

Imibuzo ebuzwa qho 

Q1: Zeziphi iindlela ezilungileyo zokuhambisa impahla United Chemical iimveliso eziya eBurkina Faso?

Ngenxa yokuba iBurkina Faso ivaliwe, sinikezela ngemigaqo yokuthumela i-CIF kwiindawo ezinkulu ezikufutshane, ikakhulu iPort of Abidjan (Côte d'Ivoire) kunye nePort of Tema (Ghana) . Xa sifika, sinikezela ngamaxwebhu apheleleyo okhuseleko lwezorhwebo kunye nezinto eziphathekayo, sinika amandla abathuthi bempahla basekuhlaleni ukuba bakhuphe ngokufanelekileyo irhafu kwaye balungiselele ukuthunyelwa kweelori emhlabeni ngqo kwindawo yakho yomgodi.

Umbuzo 2: Kutheni i-AuLeach™ GDA ilukhetho olucwangcisiweyo kwimisebenzi yokwemba imigodi yaseBurkinabe?

Ukungenisa iikhemikhali ezinobungozi kakhulu ezifana neSodium Cyanide kufuna iimvume zokuthutha ezingqongqo zeDangerous Goods (DG), ezothutho ezikhethekileyo, kwaye ngamanye amaxesha abakhweli bezokhuseleko besuka kumazibuko aselunxwemeni besiya eBurkina Faso. I-AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) yindlela engenabungozi nengenatyhefu ingako. Inika ukusebenza okufanayo kokuleaching ngelixa idlula ngokupheleleyo imiqathango yokuthutha ye-DG, yenza uthutho oluwela imida lube lula, lungabizi, kwaye lukhuselekile ngakumbi.

Umbuzo 3: Kutheni kufuneka ubulukhuni bekhabhoni obuyi-≥ 99% ekucutshungulweni kweentsimbi zeBirimian Greenstone?

Iintsimbi ezivela kwiBirimian Greenstone Belt zihlala zifuna ukugaywa kakuhle kunye nokushukunyiswa ngamandla koomatshini kwiisekethe zeCIL/CIP ukuze kuphuculwe ukubuyiswa. Ukuba i- Activated Carbon ayinawo amandla oomatshini, iya kuqhekeka ibe luthuli olucolekileyo kwaye ithwale igolide efakwe kwi-tailings facility. I-AuCarb™ Gold Recovery Coconut Shell Activated Carbon ivavanywa ukuya kubunzima obuyi- ≥ 99% , inika ukuqina okugqithisileyo okufunekayo ukugcina igolide yakho phantsi kwezi meko zinzima.
