Kugonjetsa Mkanda wa Golide wa ku Congo: Zopangira Zopindulitsa Kwambiri & Zogulitsa Zamkati mwa Dziko la DRC

Dziko la Democratic Republic of the Congo (DRC) lili ndi malo ena opezera golide opindulitsa kwambiri padziko lonse lapansi. Lili ndi malo akuluakulu ochitira malonda m'chigawo cha Haut-Uélé (monga mgodi wagolide wa Kibali wapamwamba padziko lonse) pamodzi ndi malo opangira zinthu ku Ituri , South Kivu , ndi Maniema , ndipo DRC imafuna zinthu zambiri zogwirira ntchito bwino. Komabe, chifukwa cha malo ake amkati, ogwira ntchito m'migodi akukumana ndi zopinga ziwiri zazikulu: kukwaniritsa mphamvu zobwezeretsa mphamvu m'matanki amphamvu a CIL/CIP komanso kuyang'anira zinthu zochokera m'malire a mayiko osiyanasiyana kuchokera ku madoko aku East Africa.

United Chemical Timathetsa kusiyana kumeneku ngati malo opangira zinthu mwachindunji. Timapereka Core Trio yathu ya ma reagents ochotsera zinthu omwe amapangidwira makamaka kuti agwiritsidwe ntchito kwambiri, mothandizidwa ndi akatswiri owongolera unyolo wopereka zinthu m'malire.

Matrix a Zaukadaulo ndi Kuyerekeza

1. AuCyan™ NaCN Sodium Cyanide ≥98.3%

Pa mafakitale a CIL/CIP okhala ndi mphamvu zambiri omwe amanyamula matani mamiliyoni ambiri a miyala pachaka, kuyera kwa mankhwala kumatanthauza mwachindunji kugwiritsa ntchito bwino ndalama. Timapanga ndikupereka AuCyan™ NaCN Sodium Cyanide ≥98.3% mu mawonekedwe olimba a briquette. Mwa kusunga kuyera kotsimikizika kwa ≥98.3%, timachepetsa kwambiri zinyalala zosasungunuka. Kuchuluka kumeneku kumalola akatswiri a zitsulo aku DRC kusunga alkalinity yoteteza, kuchepetsa mlingo wa reagent pa tani imodzi ya miyala, ndikutsimikizira kusungunuka kwa golide mwachangu panthawi yonse yopanga zinthu zambiri. (Kumafuna Satifiketi Yovomerezeka Yogwiritsa Ntchito / Chilolezo Cholowera ku Boma).

2. AuCarb™ Gold Recovery Coconut Shell Activated Carbon (Zitsanzo zaulere zoyesera zimapezeka mukapempha)

Kusunthika kwa makina opangidwa ndi chitsulo cholimba kwambiri m'matanki a CIL osalekeza kumatha kuswa mosavuta Carbon yosakwanira , zomwe zimapangitsa kuti golide wamtengo wapatali utayike m'madamu a tailings. AuCarb™ Gold Recovery Coconut Shell Activated Carbon (Zitsanzo zaulere zoyesera zimapezeka mukapempha) zimapangidwa motsatira miyezo yokhwima ya ASTM ndi AARL kuti athetse kutayika kwa kaboni.

• Kutsimikizira Kwaulere kwa Laboratory: Tikulimbikitsa oyang'anira mafakitale aku DRC kuti ayesere momwe timagwirira ntchito. Zitsanzo zaulere zoyesera zimapezeka ngati titapempha kuti titsimikizire kukana kwathu kwa K-value adsorption ndi kukana kwa kutayika kwa K motsutsana ndi omwe akukupatsani ntchito musanayambe kuyitanitsa malonda.

3. AuLeach™ Wothandizira Kuchotsa Golide Wosawononga Zachilengedwe (GDA) (Zitsanzo zaulere zoyesera zimapezeka mukapempha)

Kunyamula cyanide yoopsa yachikhalidwe kudutsa malire osiyanasiyana apadziko lonse lapansi (monga Kenya kapena Tanzania kupita ku Eastern DRC) kumaphatikizapo zilolezo zolimba za Dangerous Goods (DG), kuchedwa kuyang'aniridwa kwa malire, ndi ndalama zapadera zoyendera. AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) (Zitsanzo zaulere zoyesera zomwe zimapezeka mukapempha) ndi reagent ina yosaopsa 100%. Imachotsedwa ndikunyamulidwa pamisonkhano ngati katundu wamba wosaopsa, imapeza kuchuluka kwa golide kofanana ndi cyanide pomwe imachotsa kwathunthu kukangana kwa DG kudutsa malire ndikuchepetsa zoopsa zachitetezo pamalopo.

Kugonjetsa Kayendetsedwe ka Zinthu ku DRC: Ma Corridor a ku East Africa

Kupereka golide ku madera akum'mawa kwa DRC kumafuna kuyendetsedwa bwino m'njira zoyendera zapadziko lonse lapansi. United Chemical imapereka kutumiza konse kwa makontena (MOQ: 1 FCL) motsatira malamulo odalirika a CIF ku zipata zazikulu za m'mphepete mwa nyanja:

• Njira Yakumpoto (CIF Mombasa, Kenya): Ndi yabwino kwambiri pogulitsa migodi ku Haut-Uélé (Kibali) ndi Ituri . Katundu amafika ku Port Mombasa, amachotsa katundu woyendera, ndipo amadutsa mumsewu waukulu kudzera mu Uganda kupita kum'mawa kwa DRC kudzera m'malire a Aru kapena Durba.

• Central Corridor (CIF Dar es Salaam, Tanzania): Akulimbikitsidwa kuti agwire ntchito ku South Kivu (Bukavu) ndi Maniema . Sitima zimafika ku Dar es Salaam, ndipo njira zoyendera zapamtunda zimadutsa ku Rwanda/Burundi kuti zilowe ku DRC kudzera ku Goma kapena Bukavu.

• Chitsimikizo cha Mapaketi a Mafakitale: Kuti apirire makilomita masauzande ambiri paulendo wapamtunda, AuCyan™ NaCN Sodium Cyanide ≥98.3% imasungidwa m'madiramu achitsulo ovomerezedwa ndi UN mkati mwa zotengera zotsekedwa. Zogulitsa za AuCarb™ ndi AuLeach™ zomwe sizili zoopsa zimapakidwa m'matumba a PE olemera a 25kg kapena matumba akuluakulu osanyowa.

Mafunso Ofunsidwa Kawirikawiri 

Q1: Kodi njira yodalirika kwambiri yotumizira mankhwala opita ku migodi ku Haut-Uélé ndi Ituri ndi iti?

Njira yabwino kwambiri yoperekera golide ku madera akumpoto chakum'mawa kwa DRC (monga Kibali ku Haut-Uélé) ndikugwiritsa ntchito mawu athu amalonda a CIF kupita ku Doko la Mombasa (Kenya) . Kuchokera ku Mombasa, katundu amasamutsidwa kudzera mu Northern Corridor kudzera ku Uganda mwachindunji kupita kumalire akum'mawa kwa DRC. Timapereka zikalata zonse zofunika zamalonda (COA, MSDS, TDS) kuti titsimikizire kuti mayendedwe ake ndi abwino.

Q2: Kodi AuCarb™ Activated Carbon imafanana bwanji ndi miyezo yapadziko lonse lapansi monga Jacobi G208AS kapena G210AS?

Kaboni yathu ya AuCarb™ Gold Recovery Coconut Shell Activated Carbon (Zitsanzo zaulere zoyesera zimapezeka mukapempha) (magiredi a AC50, AC55, ndi AC60) ndi yotsika mtengo komanso yofanana ndi Jacobi G208AS, G209AS, ndi G210AS. Yopangidwa motsatira miyezo ya ASTM/AARL, kaboni yathu ili ndi kuuma kwa ≥ 99% ndi mphamvu ya K-value adsorption mpaka ≥ 30 Kg/t , zomwe zimaletsa kutayika kwa golide komwe kumachitika chifukwa cha kuwonongeka kwa kaboni m'matanki akuluakulu a CIL.

Q3: Kodi AuLeach™ GDA imachepetsa bwanji ndalama zoyendetsera zinthu kupita kum'mawa kwa DRC?

Kunyamula cyanide yachikhalidwe kudutsa malire osiyanasiyana apadziko lonse kupita ku DRC kumafuna zilolezo zovuta za Dangerous Goods (DG) ndi maulendo apadera ochokera ku Kenya/Tanzania kudzera m'maiko oyendera. Chifukwa AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) (Zitsanzo zaulere zoyesera zomwe zimapezeka mukapempha) zimaloledwa ndikunyamulidwa ngati katundu wamba wosaopsa, zimapewa kwathunthu malamulo oletsa a DG awa, zomwe zimapangitsa kuti anthu azitha kuwoloka malire mwachangu komanso kuchepetsa ndalama zonse zonyamula katundu.

Q4: Mwa United Chemical kupereka zitsanzo zoyesera ku labotale yathu ku DRC?

Inde, ndithudi. Timapereka zitsanzo za mayeso aulere ngati titapempha kuti tigwiritse ntchito AuCarb™ Gold Recovery Coconut Shell Activated Carbon ndi AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) . Izi zimathandiza gulu lanu la metallurgical kuyesa palokha ndikutsimikizira momwe leaching kinetics, K-values, ndi carbon hardness mu labotale yanu musanayike oda yonse ya chidebe (1 FCL).

Q5: Nchifukwa chiyani kuyera kwa ≥98.3% ndikofunikira pa Sodium Cyanide yomwe imagwiritsidwa ntchito m'mafakitale akuluakulu a DRC CIL?

Mu malo opangira zinthu zazikulu kwambiri omwe amasamalira miyala yagolide yovuta, kusunga kuchuluka kwa reagent kolondola ndikofunikira kwambiri kuti ntchito ikhale yokhazikika. AuCyan™ NaCN Sodium Cyanide ≥98.3% imapereka chiyero chotsimikizika chomwe chimachepetsa zodetsa zosasungunuka, chimakhazikitsa alkalinity yoteteza, komanso chimachepetsa kugwiritsa ntchito mankhwala onse pa tani imodzi ya miyala, zomwe zimapangitsa kuti ntchito yopitilira ikhale yogwira ntchito bwino kwambiri.
