IZambia idume kwihlabathi liphela ngobutyebi bayo obukhulu bekopolo, kodwa icandelo layo legolide liyanda ngokukhawuleza. Ukusuka kwimijikelo emikhulu yokufunyanwa kwegolide kwimveliso engaphantsi kwemveliso kwimishishini emikhulu efana neFirst Quantum's Kansanshi Mine eSolwezi (eMntla-Ntshona wePhondo), ukuya kwiiprojekthi zegolide eziphambili kwizithili zaseMumbwa, eKasenseli, naseRufuna. Nangona kunjalo, ukuvula igolide kwindawo yejoloji yaseZambia kuzisa imiqobo enzima yesinyithi kunye neyothutho efuna amaqhinga akhethekileyo e-reagent.

Kwabachwephesha abaPhambili beMetallurgists kunye nabaLawuli boThengo eZambia, iindawo ezintathu ezibuhlungu kakhulu zilawula imisebenzi yemihla ngemihla. Okokuqala, ii-ore ezinamafutha aqholiweyo kakhulu (ii-copper-gold cyanicides): Uninzi lwegolide yaseZambia lugcinwe kwiimatrices ezinobhedu oluninzi. Iiminerali zeCopper (ezifana neChalcocite, Bornite, kunye neMalachite) zisebenza njenge "cyanicides" enamandla, oko kuthetha ukuba zidla ngokukhawuleza inani elikhulu leemveliso zasimahla. i-cyanide ngaphambi kokuba inyibilikise igolide. Oku kwandisa iindleko ze-reagent kwaye kunciphisa isivuno segolide. Okwesibini, iiNkqubo zoLogistics eziValekileyo kunye neeNgxaki zeMida: Njengelizwe elingangeniswanga manzi, ukungeniswa kweekhemikhali kufuneka kudlule kwiZibuko laseDar es Salaam (eTanzania), eBeira (eMozambique), okanye eDurban (eMzantsi Afrika). Ukususa iiMpahla eziyingozi zeKlasi 6.1 (NaCN) ngeendawo zemida ezidumileyo ezifana neNakonde/Tunduma okanye iKasumbalesa kudla ngokubangela ukulibaziseka kweeveki. Okwesithathu, Imigaqo Engqongqo ye-ZEMA: I-Arhente yoLawulo lweNdalo yaseZambia (i-ZEMA) inyanzelisa imithetho engqongqo ngakumbi malunga nokukhutshwa kwe-cyanide kunye nokugcinwa kweekhemikhali eziyingozi, ifuna imigaqo ebizayo yokuthobela imithetho evela kubasebenzi bemigodi.

United Chemical iye yaqulunqa i-reagent matrix eyenzelwe ngokukodwa ukusombulula imingeni ye-ore ebukhali yaseZambia kunye nemingeni yezothutho. Ngokudibanisa izinto ezinyibilikisa ulwelo oluphezulu kakhulu, iyasebenza ICarbonkunye nezinye iindlela zokukhupha amanzi ezingezizo eziyingozi, sixhobisa imigodi yaseZambia ukuba inciphise iindleko zokusebenza, isuse ukulibaziseka kwimida, kwaye ifezekise ukubuyiselwa okuphezulu kwesinyithi.

Imibuzo Ebuzwa Rhoqo: Iikhemikhali Zokwemba Igolide eZambia

1. I-AuCyan™ ijongana njani neentsimbi zegolide ezityebileyo (ezityebileyo ngobhedu) ezixhaphakileyo eZambia?

Iiminerali zeCopper zisebenza njenge-cyanicides, zifunxa i-cyanide ngokukhawuleza ngaphambi kokuba igolide inyibilike. I-AuCyan™ (ubumsulwa obuyi-≥98.3%) inika uxinaniso olukhulu lwee-ion ze-CN⁻ zasimahla. Ngokusebenzisa amaqhinga afana nokutsalwa kwe-ammonia-cyanide okanye ukugcina amanqanaba aphezulu e-cyanide asimahla asebenzayo, i-AuCyan™ iqinisekisa ukuba impendulo yokunyibilika kwegolide ayithintelwa kukuphazamiseka kobhedu.

2. Ukusebenzisa i-AuLeach™ kusombulula njani ukulibaziseka kwezothutho oluwela umda kumda waseNakonde?

Ukuthutha iSodium Cyanide (Class 6.1) ukusuka eDar es Salaam ukuya eZambia kufuna iimvume ezingqongqo ze-hazmat kunye nee-escorts, nto leyo edla ngokubangela ukulibaziseka kweeveki kwizikhululo zemida ezifana neNakonde/Tunduma. I-AuLeach™ GDA ayinobungozi kwaye ayichazwanga. Ihlawula imithwalo njengemithwalo eqhelekileyo, inciphisa amaxesha okuhamba kwaye inciphisa kakhulu iindleko zokuthutha impahla.

3. Ngaba i-AuLeach™ iyahambelana nemigangatho ye-Zambia Environmental Management Agency (ZEMA)?

Ngokuqinisekileyo. I-AuLeach™ ayinayo i-cyanide kwaye inobuhlobo nokusingqongileyo. Inciphisa kakhulu ubuthi kwiindawo zokugcina iingceba (TSF), ihambelana ngokugqibeleleyo nemiyalelo engqongqo yokhuseleko lokusingqongileyo ye-ZEMA kwaye yenza kube lula uhlolo lokuthobela imithetho yomgodi wakho.

4. Kutheni i-AuCarb™ coconut carbon ingcono kune-carbon yamalahle yasekuhlaleni kwizityalo zaseZambia zeCIP?

Iisekethe ze-CIP zaseZambia zihlala ziquka ulusu oluxineneyo, olunamandla aphezulu okukhupha ulwelo olunamandla amakhulu okusika kwiinxalenye zekhabhoni. Ikhabhoni esekwe kumalahle ithambile kwaye iyaphuka lula, nto leyo ebangela ukulahleka kwegolide. I-AuCarb™ (ubulukhuni obuyi-≥99%) yenziwe ngamaqokobhe ekhokhonathi axineneyo, nto leyo eyenza ukuba ingabi nakuqhekeka xa isetyenziswa kakhulu ekuphembeleleni iintsholongwane.

5. Ingaba i-AuLeach™ iyahambelana nezityalo zegolide ezikhoyo kwizithili zaseSolwezi okanye zaseRufuna?

Ewe, yinto yokutshintsha indawo yokungena. I-AuLeach™ GDA isebenzisa iitanki ezifanayo zokutsala amanzi, amanqanaba e-pH (10.5-11.5), kunye Ikhabhoni esebenzayo iisekethe ze-adsorption/elution njenge Isodium cyanideAkukho nkcitho inkulu okanye utshintsho lwezityalo olufunekayo.

6. Zeziphi iindlela ezicetyiswayo zokuhambisa iikhemikhali kwiCopperbelt yaseZambia?

Iindlela ezisebenzayo kakhulu zeCopperbelt (eNdola, eKitwe) kunye nephondo laseMntla-Ntshona (eSolwezi) zidlula kwiZibuko laseDar es Salaam (eTanzania) zisebenzisa umgaqo omkhulu weTANZAM, okanye zidlula kwiZibuko laseDurban (eMzantsi Afrika) zisiya emantla zidlula eZimbabwe (umda weChirundu).

7. Imvula enkulu yexesha lonyaka eZambia iyichaphazela njani indawo yokugcina i-AuCyan™?

IZambia inexesha lemvula elinamandla. I-AuCyan™ ipakishwe kwiidrama zentsimbi ezivalwe ngokuqinileyo, eziqinisekiswe yi-UN ezineengxowa zePVC eziqinileyo, ezingangeni manzi. Ukuba zigcinwe kwindawo yokugcina impahla egqunyiweyo, eyomileyo, nengenamoya, azichaphazeleki kwaphela kukufuma okungqongileyo kunye neemvula zexesha lonyaka.

8. Ngaba i-AuCarb™ ingakwazi ukuhluba igolide ngokufanelekileyo kwiisekethe zombane zeZadra?

Ewe. Kuba I-AuCarb™ inenkqubo yokuvula elawulwa ngononophelo, igcina isakhiwo esiqinileyo seembobo zangaphakathi. Oku kuyivumela ukuba ifunxe igolide ngokukhawuleza kwisigaba se-CIL, kodwa ikwayikhulula ngokupheleleyo ngexesha lokususwa koxinzelelo oluphezulu (iinkqubo zeZadra okanye ze-AARL).

9. Abasebenzi bemigodi abangoochwephesha nabaphakathi eZambia batshintshela njani ekusebenziseni i-AuLeach™?

Ukuze kukhuliswe imisebenzi ye-ASM ejonge ukumisela nokwamkela izityalo ezincinci ze-vat leaching okanye ze-CIP, I-AuLeach™ yeyona ndawo ikhuselekileyo yokungena. Isusa iingozi ezibulalayo ezinxulumene nokuphatha i-cyanide ngaphandle kwezixhobo zokhuseleko eziphambili, nto leyo evumela ukwandiswa okukhuselekileyo kwemveliso yegolide.

10. Iingcali zesinyithi zaseZambia zingazifumana njani izixhobo zesampulu zovavanyo lwelebhu?

Abaqhubi bemigodi baseZambia banokuqhagamshelana nathi kwiwebhusayithi yethu ukuze bacele Ikhithi yeSampuli yeLebhu yasimahlaSiza kulungiselela ukuhanjiswa kwe-AuCyan™, AuCarb™, okanye i-AuLeach™ ngqo kwilebhu yakho yesinyithi eZambia ukuze kuhlolwe ngokuzimeleyo i-bottle-roll okanye i-column leach.
