Ukuphakamisa ukucutshungulwa kwegolide eHard Rock eSierra Leone: Izinto ezikwaziyo ukumelana nemozulu kwiintaba zaseBaomahun naseSula

Ukuphakamisa i-Hard Rock Gold Processing eSierra Leone: Ii-Reagents eziMelana neMozulu kwiiNtaba zaseBaomahun naseSula eLeone iikhemikhali zeprojekthi yeprojekthi yeekhemikhali Izibuko laseFreetown logistics mountains extraction AuCyan™ Sodium Cyanide NaCN AuCarb™ Recovery Coconut Shell Activated Carbon AuLeach™ Leaching Agent GDA I-arhente ye-leaching engenabungozi I-wet season cyanide storage shell activated carbon CIL Ubumsulwa obuphezulu 98.3% CIF Kangari hills metallurgy adsorption kinetics Ukuthobela imiqathango yendalo Umthengisi weekhemikhali zesodium ngqo kwifektri Abasasazi be-recovery metal No. 1 umfanekiso okhawulezayo

ISierra Leone imi kwindawo engxangxasi yotshintsho olukhulu lwemigodi. Ukuya ngaphaya kokukhutshwa kwemigodi yamandulo, ingqwalasela iye yatshintshela ekumbiweni kwegolide elukhuni, ethengiswa ngamatye aluhlaza kwiintaba zaseSula, iiNtaba zaseKangari, kunye neProjekthi yeGolide yaseBaomahun elindelwe kakhulu . Nangona kunjalo, njengoko iinkampani zemigodi zikhula ukuya kwizityalo zokucubungula iCarbon-in-Leach (CIL) kunye neCarbon-in-Pulp (CIP) ezixabisa izigidi zeetoni, iinjineli zesinyithi ziyangqubana neemeko zasekuhlaleni ezibuhlungu.

Awona manqaku aphambili entlungu? Okokuqala, ixesha lemvula elingapheliyo leenyanga ezi-6 zetropiki eliguqula izinto ezisetyenziswa ngaphakathi elizweni ukusuka kwiPort of Freetown zibe yintlekele yokuthutha, apho iilori zinokubhaqwa eludakeni olunzulu, ziveze iikhemikhali ezibuthathaka kumswakama ophezulu. Okwesibini, ukushukuma okunzima koomatshini okufunekayo kwiisekethe ezintsha zeCIL ezinamatye aqinileyo konakalisa ngamandla iCarbon esebenzayo engaphantsi komgangatho , okubangela ukulahleka kwegolide okubi kakhulu kwiintsalela. Okokugqibela, ukuqinisa iziseko zokusingqongileyo kufuna ulawulo olungcono lwamanzi lweTailings Storage Facility (TSF) ngexesha leziganeko zemvula enkulu.

United Chemical iye yaqulunqa ipotifoliyo ekhethekileyo yee-reagents zesinyithi eziphendula ngokuthe ngqo le mingeni yaseSierra Leone. Sinikezela ngomqolo weekhemikhali ovumela abaqhubi baseNtshona Afrika ukuba bagcine isivuno esiphezulu sokubuyisela, bakhusele uthungelwano lwabo lokubonelela, kwaye baqinisekise ukuthotyelwa ngokupheleleyo kokusingqongileyo.

Iimveliso Zokubuyiswa Kwegolide Eziphambili Ezilungiselelwe iSierra Leone

I-AuCyan™ Sodium Cyanide NaCN (≥98.3%)

Kwixesha lemvula elinzima eSierra Leone, ukupakisha okuqhelekileyo kweSodium Cyanide kuya kusilela, nto leyo ekhokelela ekungeneni komswakama okuyingozi, ukukhutshwa kwegesi enobuthi, kunye nokulahleka okukhulu kweekhemikhali ezisebenzayo ngaphambi kokuba zifike kwitanki yokuxuba. I-AuCyan™ iyawususa lo mngcipheko ngokupakisha okusemgangathweni womkhosi kunye nobunyulu obungenakuguquka.

Imibuzo Ebuzwa Rhoqo: I-Gold Metallurgy eSierra Leone

1. Kutheni i-AuCarb™ ibalulekile ekutshintsheni kweSierra Leone ukuya kwi-CIL ye-hard rock?

Njengoko umgodi utshintsha ukusuka ekuhlanjweni kwe-alluvial ukuya kwizityalo ezinkulu zeCarbon-in-Leach (CIL) (ezifana nezo zicwangciselwe iBaomahun), uludaka oluqinileyo lwamatye atyumkileyo lurhabaxa kakhulu. I-AuCarb™ Coconut Shell Activated Carbon inobunzima obungaphezulu kwe-≥99%, ithintela ikhabhoni ukuba yonakale phantsi koxinzelelo olukhulu kwaye igcina igolide yakho efunxiweyo ukuba ingaphumi iye kwiintsalela.

2. Ingaba kwenzeka njani United Chemical ukukhusela i-NaCN ngexesha leenyanga ezi-6 zemvula yetropiki?

Izinto ezisetyenziswa ngaphakathi eSierra Leone zihlala zijongene neendlela ezinodaka nezingenakugqithwa. Ukulwa noku, i-AuCyan™ NaCN yethu iqiniswe ngaphakathi kweengqimba ezininzi zee-polymer liners ezinzima, ezivalwe ngobushushu. Ezi zikhuselwe ngakumbi ziidrama zentsimbi ezivunyiweyo yi-UN okanye iikreyithi zomthi eziqinisiweyo, ukuqinisekisa ukuba akukho kungena komswakama nokuba ilori ilibaziseka ngenxa yemvula enkulu kangangeeveki.

3. Ngaba i-AuLeach™ GDA ingatshintsha ngokupheleleyo iSodium Cyanide ngaphandle kokutshintshwa kwezityalo?

Ewe, ngokuqinisekileyo. I-AuLeach™ Gold Leaching Agent yindawo ethe ngqo yokufaka i -sodium cyanide . Nokuba usebenzisa iseti ye-Vat Leaching okanye isekethe epheleleyo ye-CIP/CIL kwiintaba zaseSula, ungatshintshela kwi-AuLeach™ ngaphandle kokuchitha nedola enye ekutshintsheni isityalo esikhulu okanye kwizixhobo ezintsha.

4. Ngaba i-AuLeach™ iyawaphucula amaxesha okususwa kwerhafu kwiZibuko laseFreetown?

Ewe, ngokubalulekileyo. Ukususa iikhemikhali zeClass 6.1 ezinobungozi kakhulu ezifana neNaCN ngeFreetown kufuna ukhuseleko oluqinileyo, iimvume zokusingqongileyo, kwaye kudla ngokubangela ukulibaziseka kwexesha elide. Ngenxa yokuba i-AuLeach™ iqinisekisiwe kwihlabathi liphela njengengenabungozi, iyayigqitha le migaqo yeekhemikhali ezinobungozi, ivumela ukususwa ngokukhawuleza kunye nokuthunyelwa kwangoko kwindawo yakho yomgodi.

5. Ubumsulwa obuyi-≥98.3% be-AuCyan™ buyichaphazela njani imiphumo yokubuyisela kwimeko yesiqhelo?

I-cyanide engcolileyo ingenisa ii-carbonates ezingafakwanga kunye nee-base-metal complexing agents ezisebenzisa iikhemikhali zakho ngaphandle kokukhupha igolide. Ubumsulwa obuqinisekisiweyo be- AuCyan™ buqinisekisa ukuba i-cyanide esebenzayo ekhululekileyo (CN-) ifakwa kwi-slurry, nto leyo ekhokelela kwi-kinetics ekhawulezayo yokunyibilika kunye nokusetyenziswa kweekhemikhali okuphantsi ngetoni nganye ye-ore.

6. Zithini iimeko zothutho xa kuhanjiswa impahla eSierra Leone?

Umsebenzi wethu oqhelekileyo eNtshona Afrika yiCIF (Iindleko, i-Inshurensi, kunye nokuThuthwa kwempahla) ukuya kwiZibuko laseFreetown . Siphatha zonke iibhukisho zempahla yolwandle kunye ne-inshurensi yolwandle. Nje ukuba impahla ifike ngokukhuselekileyo eFreetown, iqabane lakho lezothutho lendawo lithatha ulawulo lokususwa kwempahla kunye nokuhanjiswa kokugqibela ukuya kwindawo yeprojekthi.

7. I-AuLeach™ inceda njani kulawulo lweTailings Storage Facility (TSF) ngexesha lemvula enkulu?

Ngexesha leemvula ezinkulu, amanqanaba amanzi e-TSF anokunyuka, nto leyo ebangela umngcipheko wokugcwala okungcoliswe yi-cyanide. Ukusebenzisa i- AuLeach™ engenabungozi kunciphisa kakhulu iprofayili yobuthi kwidama lakho leentsalela. Oku kunciphisa iingozi zentlekele yokusingqongileyo kwaye kunciphisa kakhulu isidingo seenkqubo ezibizayo zokucoca iikhemikhali.

9. Ngaba i-AuCarb™ ifanelekile kwisisombululo soxinzelelo oluphezulu (HPHT)?

Ewe. I-AuCarb™ yikhabhoni yeqokobhe lekhokhonathi esebenza ngobushushu eyilwe ngesakhiwo esiphakamileyo seembobo ezincinci. Ayigcini nje ngokulayisha igolide ngokukhawuleza kodwa ikwayikhupha ngokungenasiphako ngexesha leenkqubo zokususa ubushushu obuphezulu kunye noxinzelelo oluphezulu (elution), iqinisekisa ukuba ikhabhoni yakho inokuhlaziywa kwaye isetyenziswe kwakhona kwimijikelo emininzi ngaphandle kokulahlekelwa ngumsebenzi.

9. Iqela lethu le-metallurgy laseSierra Leone lingazivavanya njani iimveliso zakho?

Sikhuthaza kakhulu uvavanyo lwendawo olusekelwe kwiziphumo zovavanyo. Ungaqhagamshelana nathi ukuze ucele iisampuli zovavanyo zasimahla . Siza kulungiselela ukuthumela ubungakanani besampulu yee-carbon okanye ii-leaching agents zethu ngqo kwilabhoratri yakho eSierra Leone ukuze iqela lakho lenze uvavanyo lwalo lwe-baseline kinetic bottle-roll kunye ne-adsorption.
