Ho Tsamaea ka ho Ntša Khauta Burundi: Li-reagent tse Tsoetseng Pele tsa CIP/CIL bakeng sa Li-depositi tsa Maruo a Muyinga le Mabayi

Burundi e emela e 'ngoe ea meeli ea khauta e ka bang teng Afrika Bochabela. Ha sechaba se ntse se ntlafatsa meralo ea sona ea motheo ea merafo tlas'a tlhokomelo ea Office Burundais des Mines et de la Géologie (OBREMA), ho ntšoa ha khauta ho fetoha ka potlako ho tloha mekhoeng ea setso ea matsoho ho ea ho lifeme tse hlophisitsoeng tsa Carbon-in-Leach (CIL) le li-vat leaching. Mabanta a maholo a khauta a fumanehang liprofinseng tse ka leboea joalo ka Muyinga (literekeng tsa Butihinda le Rugari) , liprofinseng tse ka leboea-bophirima joalo ka Cibitoke (masimo a khauta a Mabayi / Cimba) , hammoho le Kirundo le Bubanza, li fana ka monyetla o moholo oa maemo a holimo bakeng sa batseteli le basebetsi ba merafo.

Leha ho le jwalo, batsamaisi ba difeme le boraditaba ba ka sehloohong ba tshepe Burundi ba kopana le mathata a ikgethang a botekgeniki le a tshebetso. Ya pele, Diketane tse Rarahaneng tsa Phepelo tse Koetsweng ke Lefatshe: Kaha ke naha e koetsweng ke lefatshe, mesebetsi ya merafo Burundi e itshetlehile haholo tseleng ya dipalangwang ya Central Corridor ho tloha Koung ya Dar es Salaam Tanzania, e kenang ka dintlha tsa moedi tse kang Kobero. Ho kenya dikhemikhale tse kotsi tsa Sehlopha sa 6.1 jwalo ka Sodium Cyanide ya setso ho kenyeletsa ho tloswa ha dinaha tse ngata, ditefiso tse hodimo tsa thepa, le tieho e kgolo ya lekgetho. Ya bobedi, Saprolite ya Letswai le Letshoa le Leholo le Majwe a Polymetallic: Bongata ba di-depositi tsa kgauta tse sa tebang tsa Burundi di na le diminerale tse boima tsa letsopa (di-slime) tse kwahelang dikarolwana tsa kgauta, tse diehisang ho dutla ha metsi, le Carbon e sebeditsweng ke moya e ditshila . Ho feta moo, di-depositi tse tebileng Mabayi di bontsha dikamano tse rarahaneng tsa polymetallic koporo-kgauta tse jang di-lixiviants tse ngata. Ya boraro, Tshireletso ya Tikoloho ho potoloha Letsha la Tanganyika: Ka tlhokomelo e tiileng ya tikoloho e sireletsang di-catch tsa noka tsa lehae le boteng ba Letsha la Tanganyika, ho tsholoha ka phoso kapa ho dutla ha mesaletsa ho ka baka ho emiswa ha taolo hanghang.

United Chemical e fana ka ditharollo tsa tshepe tse ikgethileng tse entsweng ka ho kgetheha bakeng sa tikoloho ya merafo ya Burundi. Ka mohala wa rona o matla wa dihlahiswa, diphutheloana tse thata, le diprothokholo tse ikgethang tsa dipalangwang tseleng ya Dar es Salaam, re netefatsa phepelo e tshepahalang ya reagent, ho kgutliswa ha kgauta ho hoholo, le kgotso ya kelello e laolang ya 100%.
