Amakhemikhali Okukhipha Igolide Athuthukisiwe E-Yemeni Metallurgy
Ukunqoba Izinselele Zokuphepha Eziyinkimbinkimbi, Amanzi Ane-Saline, kanye Nediphozithi Evelayo
United Chemical inikeza ubumsulwa obuqinisekisiwe be-AuCyan™ Sodium Cyanide NaCN (≥98.3%), i-AuCarb™ Gold Recovery Coconut Shell Activated Carbon esebenzayo kakhulu (≥99% Ukuqina), kanye ne-AuLeach™ Gold Leaching Agent (GDA) ebalulekile engeyona ingozi ukuze kunikezwe amandla okusebenza kwensimbi okuphephile nokusebenza kahle kuzo zonke izindawo zamaminerali ezinamandla amakhulu zaseYemen.
Indawo Yezimayini YaseYemen: Amandla Aphezulu Phakathi Kwezimo Ezinzima Zokusebenza
IRiphabhulikhi yaseYemen inengcebo enkulu kakhulu, engasetshenziswa kakhulu, kanti ukuhlola komlando kugqamisa amandla amakhulu egolide ezindaweni ezifana neMedden Valley esifundazweni saseHadhramaut. Kodwa-ke, ukuvula lezi zinsiza kudinga ukuhamba kwenye yezindawo zokusebenza eziyinkimbinkimbi kakhulu emhlabeni jikelele. Ngokwezinto zokwakha kanye nokuvikeleka , ukuthutha izinto eziyingozi kakhulu ze-DG Class 6.1 njenge- Sodium Cyanide emizileni yangaphakathi yeYemen kudinga abaphelezeli bezokuphepha abakhulu kanye nokuvunyelwa okuyinkimbinkimbi okunezingqimba eziningi. Ngokwejiyoloji kanye nesimo sezulu , imisebenzi ibhekene nokuntuleka kwamanzi okukhulu, okudinga ukusetshenziswa kwamanzi enqubo enosawoti omningi obambezela i-cyanidation kinetics, kanye nokushisa okukhulu kwasehlane okusongela ukuzinza kwamakhemikhali.
Njengomhlinzeki wokukhiqiza osezingeni eliphezulu othumela ngokuziqhenya ku Amazwe we-77 + emhlabeni jikelele, United Chemical ihlomisa amaphayona aseYemen ngezingqalasizinda zamakhemikhali ezenzelwe ukusinda nokuchuma lapha. Ukuze kugwenywe izithiyo zokuphepha ezinzima kanye nemithetho yezokuthutha eziyingozi, i-AuLeach™ yethu eqinisekisiwe emhlabeni wonke engeyona ingozi inikeza indawo entsha yokungena. Kumasekethe avunyelwe, i-AuCyan™ yethu emsulwa kakhulu kanye ne-AuCarb™ engagugiyo ikhulisa isivuno ezindaweni ezinzima zosawoti.
Ukuze siqinisekise ukuthi iziteshi zokuhambisa ziphephile, aziphazamiseki esifundeni, senza ukuthengiselana ngaphansi kwemigomo ye-FOB (amachweba aseChina) noma ye-CIF ngqo ezindleleni zokuhweba eziyinhloko njengePort of Aden noma iPort of Mukalla . Sisekelwa yi-Minimum Order Quantity (MOQ) ye- 1x20' FCL , sinikeza ukusebenza kahle ngqo kusuka efektri kuya eningizimu ye-Arabian Peninsula, sinike amandla ama-ejenti akho endawo okuthuthwa kwempahla ukuphatha ukulethwa kokugcina ngaphakathi ezweni ngokuphephile.
1. Ukunqoba Izithiyo Zokusebenza zaseYemen
Ukuphathwa Kwezokuphepha Okukhulu
Ukuthutha i-DG Class 6.1 cyanide enobuthi obukhulu ngaphakathi ezweni kusuka emachwebeni asogwini (i-Aden/Mukalla) kuhilela izingozi ezinkulu zokuphepha kanye nezindleko ezinkulu zokuphelezela ezihlomile. Indlela yokususa imfucuza engeyona ingozi futhi enobungani nemvelo iqeda ngokuphelele le nkinga ebalulekile, ivumela ukuthuthwa njengempahla evamile.
Amanzi Anenqubo Enosawoti Oningi
Ukuntuleka okukhulu kwamanzi asehlane kuphoqa ukusetshenziswa kwamanzi angaphansi komhlaba anosawoti omningi. Lokhu kunciphisa kakhulu umoya-mpilo oncibilikisiwe, kubambezele kakhulu i-Elsner dissolving equation futhi kubangele ukukala okukhulu emapayipini ngaphandle kokuthi kulwiswane nama-reagent amsulwa kakhulu, afakwe kahle.
Ukucindezeleka Okukhulu Kokushisa Kwasehlane
Izindawo zasehlane zangaphakathi eYemen zibekezelela ukushisa okukhulu. Ukupakisha kwamakhemikhali okujwayelekile kungabhekana nokwehluleka kokushisa, okuholela ekushayweni okuyingozi ngaphandle kwegesi. Ama-reagent adinga ukupakisha okunzima, okuqinisekiswe yi-UN ukuze kugcinwe ukuzinza okuphelele ngesikhathi sokuthuthwa nokugcinwa.

6. Ingabe zikhona izindleko zezindleko ezinkulu (i-CAPEX) zokushintshela ku-AuLeach™?
Akukho zindleko ze-CAPEX ezidingekayo ngoba i-AuLeach™ yakhelwe esikhundleni se-100% yokungena. Abaphathi bezitshalo akudingeki bathenge amathangi amasha okukhipha amanzi, bashintshe izinhlelo zabo zokunisela nge-Heap leach, noma bashintshe amasekethe abo okususa i-carbon. Umane ufake i-cyanide esikhundleni se-AuLeach™ ngqo enkambisweni.
7. Yiziphi izinhlobo zama-ore ezingacutshungulwa kusetshenziswa i-AuLeach™ Non-Hazardous reagent?
I-AuLeach™ inobubanzi obukhulu bokusetshenziswa. Ngokusho kwe-Technical Data Sheet yayo, isebenza kahle kakhulu kuma-ore ayinhloko, ama-ore e-oxide, ama-ore angama-semi-oxide, ama-ore e-sulfide, ama-gold concentrate, kanye nama-cyanide tailings kuzo zombili imisebenzi ye-Carbon-in-Pulp kanye ne-Heap leaching.
8. Amalabhorethri e-metallurgical ahlola kanjani ukuhlushwa kwe-AuLeach™?
Amalabhorethri ahlola ukuhlushwa kwe-AuLeach™ ngendlela ejwayelekile ye-titration yamakhemikhali. Lokhu kuhilela ukusebenzisa i-analytical grade silver nitrate complexing agent kanye ne-rhodanine indicator. Ngesikhathi se-titration, isixazululo siyashintsha sisuka kophuzi siye kobomvu, kanti ama-milliliters e-complexing agent asetshenziswayo abonisa ngokunembile ukuhlushwa okusebenzayo kwe-reagent.
9. Yiluphi uhla lwe-pH olufanele kakhulu lokusebenzisa i-AuLeach™ kumasekethe okukhipha amanzi?
Ububanzi be-pH yokusebenza obuqinisekisiwe be-AuLeach™ buphakathi kuka-10.5 no-12. Lokhu kuhambisana kahle nezifunda zendabuko ze-cyanidation, okusho ukuthi abaqhubi bezitshalo bangaqhubeka nokusebenzisa i-lime ejwayelekile emanzi ukuphatha i-slurry alkalinity ngaphandle kokushintsha izinqubo zabo zamanje.
10. Ingabe nihlinzeka ngezokuthutha eziwela umngcele ezivela emazweni angomakhelwane?
Cha, sikwenqabela ngokuqinile ukusetshenziswa kwamaloli awela imingcele ukuze sithumele amakhemikhali kwamanye amazwe. Ngenxa yemithetho eqinile yokuphepha yamazwe ngamazwe elawula amakhemikhali ayingozi kanye nobunzima bokuphepha kwesifunda, sivikela uchungechunge lwethu lokuhlinzeka kuphela ngokuthunyelwa kwezitsha zasolwandle (i-FOB noma i-CIF) emachwebeni okuya kuwo.
11. Iyini i-Minimum Order Quantity (MOQ) yokuthumela e-Yemen?
Inani lethu elincane kakhulu le-oda (MOQ) lingu-1x20' FCL (Umthwalo Ogcwele Wesitsha). Le nqubomgomo isebenza kuwo wonke umuntu ku-AuCyan™, AuCarb™, kanye ne-AuLeach™ ukuqinisekisa amanani aqondile embonini, ukuvikela ubuqotho bokupakisha, kanye nokuthuthukisa izindleko zokuthutha zasemanzini.
I-12. Kwenzeka kanjani United Chemical ukuqinisekisa ukuphepha kochungechunge lokuhlinzeka?
Siqinisekisa ukuphepha kweketanga lokuphakelwa ngokufeza zonke izinkokhelo ngaphansi kwemigomo eqinile ye-FOB noma ye-CIF yolwandle. Sisebenza kuphela ngezilinganiso ze-FCL ezingama-1x20' kanye nokupakishwa okuqinisekiswe yi-UN, siqinisekisa ukuthi imithwalo yempahla eyingozi yolwandle iphathwa kuphela yimigqa yokuthumela yamazwe ngamazwe ye-tier-1 ngqo emachwebeni ase-Yemen, sidlulisa ezokuthutha zangaphakathi ezweni ngokuzibophezela kuma-ejenti omthengi asendaweni.
