1. Heerka-1 Miinooyinka Shiinuhu Taageero (Kamoa-Kakula, TFM, Sicomines)
Cidda arrintani khusaysa: Agaasimayaasha wax soo iibsiga ee hawlgallada ay lahaanshaha Shiinuhu ka wadaan miinada, laakiin qurba-joogta ku hadasha Ingiriisiga iyo kooxaha farsamada Kongo ayaa maamula warshadda.
Dhibka jira: miinooyinka ay Shiinuhu taageeraan ee DRC ayaa wajahaya isbarbar-dhigga wax iibsiga. Shirkadaha waalidkood (Zijin, CMOC, China Railway) waxay leeyihiin silsilado sahayda qoto dheer ee Shiinaha - laakiin FLSmidth iyo Metso OEM kaydka waxaa laga keenaa Yurub qiimaha Yurub. Beddelka - qaybaha xidhashada summada Shiinaha - badiyaa waxa ka maqan qaabaynta u adkaysta aashitada ee wareegyada Katanga cobalt ay dalbadaan. Hawlgallada soo saarista sabbaynta waxay xidhaan qaybo ka mid ah macdanta cobalt cobalt Katanga Congo beddelka, natiijadu waa wareegga wax iibsiga ee u dhexeeya "qiimihiisu jaban yahay laakiin muddada gaaban" iyo "qaali ah laakiin waara" oo aan lahayn meel dhexe.
OEM-shahaadada qiimaha warshadaha Shiinaha - 40-50% ka hooseeya FLSmidth/Metso European OEM, oo leh polyurethane u adkaysta aashitada
Taageerada wax iibsiga labada luqod - Mandarin ee iibka shirkadda waalidka ee Shiinaha, Ingiriisiga kooxaha farsamada goobta ee DRC
Kaydka Dar es Salaam ee Kamoa/TFM/Sicomines moodooyinka ugu sarreeya - buuxinta 25-maalmood, ma aha 10-usbuuc
Daraasadda Kiis: TFM (Tenke Fungurume Mining) - Kala-guurka Aashitada u adkaysta
Asalkii hore
Marka TFM - oo ay maamusho CMOC (Shiinaha Molybdenum), mid ka mid ah hawlaha ugu weyn ee DRC-cobalt ka baaraandegidda qiyaastii 20,000 tpd iyada oo loo marayo FLSmidth Dorr-Oliver unugyada sabbeynta unugyada - waxay soo saartay hindise rotor stator DRC Copperbelt OEM sahayda, qiimayntu waxay diiradda saaraysaa hal doorsoome: wareegga wareegga kobalt. Hawlgalku wuxuu waddaa wareegyada sabbeynta naxaasta iyo kobalt-ka - wareegga kobaltku wuxuu ku shaqeeyaa pH 3.2-4.0 sababtoo ah ku darida sulfuric acid. Isticmaalka rotor-ka sannadlaha ah: ku dhawaad 45 qaybood oo dhan DO-100 iyo DO-160 nooc.
Caqabadda
Rotors wareegyada Cobalt (DO-100): celceliska nolosha adeegga 9.2 bilood - 35% ka gaaban rotors wareegyada naxaasta ee isku midka ah (14.1 bilood)
Sababta xididka: hydrolysis polyurethane acid-catalysed ayaa lagu xaqiijiyay falanqaynta FTIR oogada oo muujinaysa nabaad-guurka ester-carbonyl
Kharashka rotor-ka sannadlaha ah: USD $378,000 (Qiimaha OEM Yurub, Lubumbashi degay)
Waqtiga hogaaminta OEM: 9-11 usbuuc laga bilaabo Danmark ilaa Lubumbashi iyada oo loo sii marayo Dar es Salaam
Xalkayaga
Acid polyurethane DO-100 iyo DO-160 rotors oo la geeyay wareegga cobalt (unugyada 18) ee Maarso 2024. Wareegga naxaasta wuxuu hayaa qaabaynta caadiga ah ee PU. Isbarbardhigga la xakameeyey: 16-bilood la socodka (Maarso 2024 - Jun 2025), adkaanta Shore bishii kasta iyo cabbirka miisaanka, falanqaynta dusha saddex biloodlaha ah ee FTIR.

Maxaad u doorataa RIOLATEX?
Katanga- Silsilad sahayda oo karti leh
Xarunta isku dhafka ee Dar es Salaam - 1,500 km ilaa Lubumbashi, oo aan 11,000 km u jirta Danmark. Dhalmada 25-35 maalmood, ma aha 10-12 toddobaad. Hawlgallada soo saarista sabbeynta xidho qaybo ka mid ah macdanta cobalt ee Katanga Congo beddelka, kala duwanaanshaha saadka oo keliya ayaa caddaynaya beddelka
Shuraakada kastamka Tansaaniya - waxaanu ka qabanaa waraaqaha laga bilaabo dekedda Dar ilaa albaabka miinada ee Katanga; DDP Lubumbashi ama Kolwezi
Khibrada miinada ee Shiinuhu uu taageeray - soo iibinta laba luqod, dalacsiinta shirkadda waalidka ee Shiinaha, gaarsiinta goobta DRC

FAQ
S: Ma xaqiijin kartaa in FLSmidth-kaagu ku habboon yahay rotor stator unugga sabbaynaya qaybo DRC ah uu daboolayo labada nooc ee Dorr-Oliver iyo Metso TankCell ee laga isticmaalo Kamoa-Kakula, TFM, iyo Sicomines?
J: Haa — FLSmidth Dorr-Oliver DO-50 ilaa DO-300 iyo Metso TankCell OK-20 ilaa OK-200. Kamoa-Kakula waa Metso-ka sarreeya, TFM waa FLSmidth-ka sarreeya, Sicomines-na waa mid isku dhafan - waxaan ka daboolnaa dhammaan saddexda qaabeynta hal xarun wax soo saar. DO-100, DO-160, iyo OK-100 ayaa lagu hayaa kaydka isku-darka Daarusalaam ee soo jiidashada degdega ah. Hawlaha uu Shiinuhu taageero (Zijin, CMOC, shirkadaha kooxda tareenada ee Shiinaha), waxaanu ku dacwayn karnaa waaxda wax iibsiga ee shirkadda waalidkaa ee Shiinaha gudaha RMB anagoo si toos ah ugu soo dirayna albaabka miinada ee DRC.
S: Qaabayntaada aashitada u adkaysata - waxaan u baahanahay dukumeenti si aan u caddeeyo isbedelka qeexida kooxdayada farsamada. Ma bixin kartaa xogta tijaabada isbarbardhigga? J: Waxaan bixinaa xirmo cadeymo farsamo oo rasmi ah oo ay ku jiraan: (1) la dedejiyey xogta tijaabada hydrolysis (ASTM D3137) marka la barbar dhigo PU-da aashitada u adkeysata iyo. heerka PU ee pH iyo heerkulka wareeggaaga; (2) FTIR spectroscopy oo muujinaya haynta ester carbonyl gabowga ka dib; (3) Qalloocyada xajinta adag ee xeebta in ka badan 2,000 saacadood oo tijaabo degdeg ah; iyo (4) xogta daraasadda kiis TFM (aan la magacaabin haddii la codsado). Waxaan sidoo kale ku dari doonaa talo ku saabsan haddii wareeggaaga naxaasta ah uu si dhab ah ugu baahan yahay qaabeynta u adkeysiga aashitada ama ay ku sii socon karto heerka PU - kama jebin doono kiimikada aadan u baahnayn.
