Ukuphakamisa Ukubuyiswa Kwegolide eMadagascar: Izixazululo Zamakhemikhali Ezilungiselelwe
Imboni yezimayini zegolide yaseMadagascar inamandla amakhulu, ebonakala ngamasimu egolide acebile ngokomlando njengeMaevatanana , iBetsiaka , kanye nezindawo eziyinhloko ezishintshayo esifundeni saseDabolava . Isizwe esiyisiqhingi okwamanje sidlula ekuguqukeni okubalulekile, sisuka ekufakweni kwe-alluvial okungakahleleki siye ezitshalweni zokucubungula ezihlelekile, ezisebenzisa imishini kanye nokusebenza okusemthethweni kwe-CIL/CIP. Kodwa-ke, lolu shintsho luhlangatshezwana nezinselele ezihlukile zensimbi kanye nezendawo.
Kubasebenzi Bezimayini kanye Nabasebenza Ngensimbi eMadagascar, kunezithiyo ezintathu eziyinhloko. Okokuqala, Ama-Ore E-Lateritic Anebumba Eliphezulu: Ingxenye enkulu yegolide laseMadagascar igcinwe enhlabathini ye-lateritic, okuholela ekuqhekekeni okukhulu kakhulu kwama-liscosity emathangini okukhipha amanzi. Le ndawo e-viscous ibangela ukuguguleka okukhulu ngokomzimba ku -Carbon esebenzayo , okuholela ekulahlekelweni okukhulu kwegolide. Okwesibili, Ukuthunyelwa Kweziqhingi Nomswakama Wezindawo Ezishisayo: Zonke izinto ezifakwayo zamakhemikhali kumele zifike ngemithwalo yolwandle. Ukuhlanganiswa komswakama omkhulu wezindawo ezishisayo kanye nokuhamba olwandle okuyinkimbinkimbi kudinga ama-reagents ukuthi abe nokupakishwa okungenaphutha, okumelana nesimo sezulu. Okwesithathu, Ukulungiswa Okuphephile Kwezinto Zokusebenza: Njengoba uhulumeni ekhuthaza amaqembu Ezokusebenza kanye Nezokumbiwa Ezincane (ASM) ukuthi asebenze ngokusemthethweni, ukwamukelwa kwezindlela zokukhipha eziphephile, ezingenabungozi kubalulekile ukuvikela ukuhlukahluka okuhlukile kweMadagascar.
United Chemical uklame isethi ekhethekile kakhulu yama-reagent okucubungula igolide aklanyelwe ngqo izimo ezinzima zaseMadagascar. Kusukela ekuqineni kakhulu Ikhabhoni Esebenzayo Yenzelwe ama-slurries amakhulu e-laterite, ama-lixiviants angewona ingozi ukuze kukhuliswe ngokuphepha, sinikeza i-matrix yamakhemikhali ephelele ukuze kwandiswe inzuzo yakho yokusebenza.
I-Reagent Matrix Engcono Kakhulu Yezitshalo Zegolide ZaseMalagasy
I-AuCyan™ Sodium Cyanide NaCN (≥98.3%)
Ukusebenza kahle kokugeleza kwamanzi kuqala ngobumsulwa obungaguquki kanye nokupakishwa okuphephile kwemithwalo yolwandle okukwazi ukumelana nesimo sezulu saseMadagascar esishisayo.
Okungalingani ≥98.3% Ubumsulwa: Yenziwe ngezindinganiso eziqinile, i-AuCyan™ inikeza ukuhlushwa okukhulu kwama -ion e-cyanide yamahhala . Lokhu kuqinisekisa i-kinetics yokuncibilika kwegolide okusheshayo, okuvumela izitshalo eMaevatanana ukuthi zilondoloze amazinga aphezulu okululama ngisho nalapho zicubungula ama-ore ayinkimbinkimbi noma aphikisayo kancane.
Ukuqina Kwasolwandle Nasezindaweni Ezishisayo: Ukuze kulwiwe nomswakama ophezulu woLwandlekazi i-Indian kanye nokugcinwa isikhathi eside, i-AuCyan™ ipakishwe ezigubhuni zensimbi eziqinisekiswe yi-UN ezinezikhwama ze-PVC eziqinile neziqinile ezivalwe kahle. Lolu hlelo olunezithiyo eziningi luvala ngokuphelele umswakama, luqinisekisa ukuthi ikhemikhali ihlala yomile futhi inamandla ngokugcwele lapho ifika endaweni yakho.

I-AuLeach™ Gold Leaching Agent (GDA) - Ayiyona Ingozi
Ukuze imisebenzi efuna izindlela zokukhipha eziphephile noma ukuzulazula ekumisweni kwezimayini zobuciko, kubalulekile ukusebenzisa i-lixiviant ethembekile nephephile.
Imisebenzi Ephephile Nengeyona Eyingozi: I-AuLeach™ iyi-ejenti yokukhipha igolide engenangozi, engenayo i-cyanide. Iqeda ngokuphelele izingozi ezinkulu zokuphatha ezihlobene namakhemikhali endabuko. Lokhu kunikeza indawo yokusebenza ephephile kubasebenzi bezimayini futhi kunciphisa kakhulu ubunzima bokugcinwa nokuphathwa kwamakhemikhali.
Ukuhlanganiswa Kwezitshalo Okungenamthungo: Yakhelwe njengokufaka esikhundleni sokufaka ngqo, i-AuLeach™ isebenza kahle emazingeni ajwayelekile e-alkaline pH (10.5-11.5) isebenzisa imishini yakho ekhona yokukhipha i-vat noma i-CIL/CIP, okudinga ukutshalwa kwezimali okungekho nhlobo ukuze ishintshe.
Ukulethwa Kwezimpahla Zasolwandle Okuthembekile Nokuthengwa Kwasechwebeni (CIF Toamasina)
Ukuhlinzeka ngempahla ezweni eliyisiqhingi kudinga ulwazi olujulile kwezokuthutha olwandle. United Chemical isebenza ngokunamathela ngokuqinile ezindinganisweni zokuhweba zamazwe ngamazwe, igxile ekuletheni izinto zakho ngokuphephile echwebeni lesango.
Izinsizakalo Zochwepheshe be-CIF kanye ne-FOB: Sinikeza kuphela imigomo yobungcweti ye -CIF (Izindleko, Umshuwalense, kanye Nokuthutha) kanye ne-FOB (Ukungena Kwamahhala Esikebheni) . Sisebenzisana nezinkampani ezihamba phambili zokuthutha olwandle ukuqinisekisa ukuthi imigqa yokuthumela eqondile nephephile iya echwebeni laseToamasina (eTamatave) , ichweba eliyinhloko lezentengiselwano laseMadagascar.
Ukudluliselwa Kwechweba Okusebenzayo: Sihlinzeka ngemibhalo yokuthumela ngaphandle ephelele neqediwe ngokuphelele (kufaka phakathi ukuthobela imithetho eqinile ye-hazmat ye-NaCN). Lokhu kunika amandla abathengisi bamasiko baseMalagasy kanye nabathumeli bempahla ukuthi bakhiphe ngokushesha futhi bahlele ukuthuthwa okuphephile kwangaphakathi ezweni ukuya endaweni yakho yemayini.
Qinisekisa Ukusebenza Kuma-Ore Akho
Ingabe ama-ore e-laterite anobumba oluningi abangela ukuwohloka kwekhabhoni noma ukubuyiselwa kabi? Simema ochwepheshe bensimbi kanye nabaphathi bezitshalo kulo lonke elaseMadagascar ukuthi bacele amasampula wamahhala e-AuCarb™, noma i-AuLeach™ ukuze kuhlolwe elebhu ngokuzimela.
