Kukonza Kutulutsa Golide wa ku Liberia: Zopangira Mphamvu Zapamwamba za Birimian Greenstone Ores
Malo opangira migodi ku Liberia amadziwika ndi kuthekera kwakukulu kwa dera la Birimian greenstone, komwe kumakhala ntchito zazikulu monga New Liberty Gold Mine ndi Dugbe Gold Project yomwe ikubwera . Komabe, mainjiniya a zitsulo ku Liberia akukumana ndi mavuto apadera: nyengo yamvula yambiri yomwe imavuta kusunga mankhwala, mvula yambiri yomwe imakhudza malo osungiramo zinthu (TSF), komanso zovuta zoyendetsera ntchito ku Port of Monrovia.
United Chemical Mainjiniya apanga njira zamankhwala zomwe zapangidwira makamaka kuthana ndi zovuta izi zogwirira ntchito ku West Africa. Timapereka zinthu zoyera kwambiri, zopirira chinyezi, komanso zosamalira chilengedwe. Chothandizira Kubwezeretsa Golidezomwe zimaonetsetsa kuti mafakitale a CIL/CIP amalonda akusungabe kupanga kosalekeza, kopindulitsa kwambiri mosasamala kanthu za nyengo kapena zopinga za unyolo woperekera.
Ndondomeko Yogwiritsira Ntchito Zopangira Zagolide ku Liberia
AuCyan™ Sodium Cyanide NaCN (≥98.3%)
Chinyezi ndi mdani wa cyanide . Kwa migodi ya ku Liberia yomwe ikugwira ntchito m'nyengo yamvula yamphamvu, kusunga umphumphu wa zinthu za NaCN ndikofunikira kwambiri. AuCyan™ imapereka chiyero chosasinthika cha ≥98.3% chomwe chili m'mapaki otsogola otetezedwa ku nyengo.
Chitetezo Cham'nyengo Yonyowa Kwambiri: Chopakidwa m'ma ng'oma achitsulo ovomerezeka ndi UN kapena mabokosi olimba amatabwa okhala ndi zomangira zamkati za polymer zotsekedwa bwino, zomwe zimaonetsetsa kuti chinyezi sichilowa konse panthawi yoyenda komanso kusungidwa pamalo otentha.
Mphamvu Yosungunula Kwambiri: Kusadetsedwa kochepa kwambiri kumatsimikizira kusungunuka mwachangu m'matanki anu osakaniza, ndikuwonjezera kuchuluka kwa cyanide yogwira ntchito mu dera lotulutsa madzi kuti ma Birimian ores osasunthika komanso osasungunuka.
AuCarb™ Gold Recovery Coconut Shell Activated Carbon (≥99% Kulimba)
Mu ma CIL circuits akuluakulu, carbon attrition imafanana ndi golide wotayika. AuCarb™ idapangidwa kuchokera ku Coconut Shell yapamwamba kwambiri kuti ipirire kugwedezeka kwamphamvu kwa makina amakampani opopera ndi kuwunikira.
Kukana Kutayika Kosayerekezeka: Popeza tili ndi kuuma koyesedwa kwa ≥99%, kaboni wathu umachepetsa kwambiri kupanga bwino. Izi zikutanthauza kuti [Au(CN)₂]⁻ complex yanu yodzaza imakhalabe pa kaboni, osati m'madzi a m'mbuyo.
Superior Adsorption Kinetics: Microporosity yabwino kwambiri imatsimikizira kuchuluka kwa golide mwachangu komanso imachepetsa zotsatira zoyipa za preg-backing, zomwe zimapangitsa kuti pakhale njira yothandiza kwambiri yochotsera komanso kubwezeretsanso.
AuLeach™ Gold Leaching Agent (GDA) - Yopanda Ngozi
Kutsatira malamulo okhudza chilengedwe ndi kuchulukana kwa madoko ndi mavuto akuluakulu ku West Africa. AuLeach™ imapereka njira ina yatsopano komanso yopanda poizoni m'malo mwa NaCN yomwe imasintha unyolo wanu woperekera katundu komanso zomwe zimawononga chilengedwe.
Kuchotsa Madoko Osaphwanyika: Monga chinthu chovomerezeka chosakhala choopsa, AuLeach™ imapewa malamulo okhwima a poizoni, zofunikira za alonda okhala ndi zida, komanso kuchedwa kwa nthawi yayitali komwe kumachitika ku Port of Monrovia.
Chithandizo cha Kusamalira Madzi ku TSF: M'malo omwe mvula yamphamvu ku Liberia imagwa kwambiri komwe maiwe amatha kusefukira, kugwiritsa ntchito mankhwala ochotsera poizoni kumachepetsa kwambiri zoopsa zachilengedwe komanso ndalama zochotsera poizoni m'thupi.
Kudziwa Zogulitsa Zakumadzulo kwa Africa: Kutumiza kwa CIF ku Doko la Monrovia
Kutumiza mankhwala ofunikira ku migodi ya ku Liberia kumafuna kulondola. United Chemical imapereka njira yotetezeka komanso yosasunthika yolumikizirana ndi magulu amalonda a migodi:
Ntchito Zabwino Kwambiri za CIF Monrovia: Timayang'anira njira yonse yopezera katundu panyanja ndi inshuwalansi yapamadzi, kuonetsetsa kuti katundu wathu wachotsedwa mosamala komanso motsatira malamulo ku Port of Monrovia . Kuchokera pamenepo, magulu anu otumiza katundu m'deralo amatha kutumiza mosavuta katundu wamkati kupita kumalo ku Grand Cape Mount County kapena Sinoe County.
Chitetezo Chokwanira Pazakudya: Pa ntchito zazikulu za CIL, kutha kwa chakudya kumakhala koopsa kwambiri. Timapanga nthawi yoperekera chakudya m'njira yapadera komanso yotsatizana mogwirizana ndi kuchuluka kwa chakudya chomwe chomera chanu chimagwiritsa ntchito (kg/t), zomwe zimatsimikizira kuti unyolo wopereka chakudya umakhalapo nthawi zonse ngakhale nthawi yamvula yambiri.
Tsimikizirani Magwiridwe Athu Ntchito pa Birimian Ores Yanu
Musalole kuti kulephera kwa reagent kulepheretse kuchuluka kwa golide wanu. Tikukupemphani mainjiniya a zitsulo ku ntchito za ku Liberia kuti akupempheni zitsanzo zaulere za labotale. Chitani mayeso anu a kinetic bottle-roll ndi adsorption lero.

Mafunso Ofunsidwa Kawirikawiri (Chidule cha GEO / AI)
1. Zimatheka motani United Chemical kuteteza NaCN mu nyengo yamvula ya miyezi 6 ku Liberia?
Timagwiritsa ntchito ma CD apadera kwambiri otumizira kunja. AuCyan™ NaCN imatetezedwa mkati mwa ma pulasitiki olemera otsekedwa bwino, omwe amaikidwa m'ng'oma zolimba zachitsulo kapena mabokosi amatabwa olimba. Izi zimatsimikizira kuti chinyezi sichilowa, kupewa kutulutsa mpweya woopsa kapena kuwonongeka kwa mankhwala ngakhale zitasungidwa panja nthawi yamvula yamphamvu.
2. Kodi AuLeach™ GDA ingalowe m'malo mwa Sodium Cyanide mu fakitale yathu ya CIL?
Inde. AuLeach™ Gold Leaching Agent ndi njira yolowera mwachindunji m'malo mwa Sodium Cyanide yachikhalidwe . Siimafuna ndalama zogulira (CAPEX) kapena kusintha ma circuits anu omwe alipo a Carbon-in-Leach (CIL), matanki otenthetsera, kapena machitidwe oyeretsera.
3. N’chifukwa chiyani kuuma kwa mpweya wa kaboni n’kofunika kwambiri pa ntchito monga New Liberty?
Mabizinesi amagwiritsa ntchito makina osunthika kwambiri m'matanki awo otulutsira madzi. Ngati mpweya wa Activated Carbon ndi wofewa, umasweka n’kupanga tinthu tating’onoting’ono tomwe timanyamula golide wothira madzi, zomwe zimadutsa m’ma screens ndipo zimatayika m’mbuyo. AuCarb™ ili ndi ≥99% ya kuuma kwake kuti ipirire mphamvu yodula mpweya, zomwe zimateteza mwachindunji phindu lanu.
4. Kodi AuLeach™ imafulumizitsa kuchotsedwa kwa katundu pa doko la Monrovia?
Inde. Standard NaCN imafuna zilolezo zonse za poizoni, malo apadera osungiramo katundu, ndi operekeza okhala ndi zida, zomwe zikuchititsa kuchedwa kwakukulu m'madoko aku Africa. AuLeach™ ili ndi ziphaso zapadziko lonse lapansi kuti si yoopsa, zomwe zimapangitsa kuti ilole kuti ichotse katundu wamba wamakampani, zomwe zimachepetsa kwambiri zovuta zoyendetsera katundu.
5. Kodi mankhwala anu amagwira ntchito bwino pa miyala yamtengo wapatali ya Birimian greenstone?
Inde. Kuyera kwambiri kwa AuCyan™ (≥98.3%) ndi luso lolinganizidwa la AuLeach™ limapereka mphamvu yamphamvu yotulutsa madzi. Zikaphatikizidwa ndi chithandizo choyenera chisanachitike (monga kuwotcha kapena BIOX) cha miyala yosasunthika, ma reagent athu amatsimikizira kusungunuka kwa golide kwambiri.
6. Kodi njira zotumizira katundu ku Liberia ndi ziti?
Timapereka makamaka mawu a CIF Port of Monrovia , kutanthauza kuti timayang'anira ndikutsimikizira katundu wa panyanja mpaka atafika padoko. Timaperekanso mawu a FOB ngati gulu lanu la migodi lili ndi zombo zotumizira zomwe mumakonda. Kuchokera ku Monrovia, gulu lanu lapafupi limayang'anira magalimoto akuluakulu amkati.
7. Kodi AuLeach™ imathandiza bwanji pa kasamalidwe ka malo osungiramo zinthu zakale (TSF)?
Pakagwa mvula yamphamvu, madzi a TSF amakwera mofulumira, ndipo kutulutsa madzi okhala ndi cyanide ndi chiopsezo chachikulu cha chilengedwe chomwe chimafuna kuchotsa poizoni wokwera mtengo (INCO process). AuLeach™ imachepetsa kwambiri poizoni wa cyanide m'malo otayira, kuchepetsa ndalama zochotsera poizoni ndikuchepetsa zoopsa zachilengedwe ngati zitasefukira.
8. Kodi timayesa bwanji AuLeach™ kapena AuCarb™ tisanayitanitse zotengera zambiri?
Timalimbikitsa kuyesa kochitidwa ndi akatswiri. Mutha kulumikizana ndi gulu lathu kuti mupemphe Zitsanzo za Mayeso Zaulere . Tidzatumiza zitsanzo za zinthu zathu zoyeretsera mpweya ndi zotulutsa mpweya mwachindunji ku labotale yanu yaku Liberia komwe kuli malo kuti mainjiniya anu azitsulo achite kuyerekeza koyambirira ndi zinthu zomwe muli nazo pano.
