Te Whakarei Ake i te Tukatuka Koura i te Kōhatu Mārō i Sierra Leone: Ngā Tauhohenga Ātete-Āhuarangi mō ngā Maunga Baomahun me Sula
Kei te tū a Sierra Leone i te pari o tētahi panonitanga nui o te keri. I tua atu i te tangohanga whenua tawhito, kua nekehia te arotahi ki te keri koura toka mārō nui, arumoni i roto i ngā whitiki kōhatu matomato o ngā Maunga Sula, ngā Puke o Kangari, me te Kaupapa Koura Baomahun e tino tumanakohia ana . Heoi, i te mea e piki haere ana ngā kamupene keri ki ngā tipu tukatuka Waro-i-te-Rohe (CIL) me te Waro-i-te-Pulp (CIP) e maha-miriona tana te rahi, kei te tūtaki ngā miihini whakarewa ki ngā āhuatanga tūturu o te rohe.
Ko ngā tino take mamae? Tuatahi, he wā ua nui e ono marama te roa e huri ana i ngā mahi kawe waka mai i te Tauranga o Freetown hei moemoeā kino, ka taea te mau i ngā taraka ki roto i te paru hohonu, ka whakaatuhia ngā matū tairongo ki te haumākū nui. Tuarua, ko te whakaohooho mīhini nui e hiahiatia ana i roto i ngā ara iahiko CIL hou ka tino whakangaro i te waro whakahohe iti iho i te paerewa , ka puta he ngaronga nui o te koura ki roto i ngā para. Hei whakamutunga, ko te whakakaha i ngā anga taiao e hiahia ana kia pai ake te whakahaere wai o te Whare Rokiroki Para (TSF) i te wā o te ua nui.
United Chemical kua hangaia he kohinga matū motuhake o ngā matū whakarewa hei whakautu tika i ēnei wero o Sierra Leone. Ka whakaratohia e mātou te pou tuara matū e āhei ai ngā kaiwhakahaere o Āwherika ki te Hauāuru ki te pupuri i ngā hua whakaora teitei, te tiaki i ā rātou mekameka tuku, me te whakarite kia tutuki katoa ngā whakaritenga taiao.
Ngā Hua Whakaora Koura Matua i Whakaritea mō Sierra Leone

Ngā Pātai Auau: Te Mahi Whakarewa Koura i Sierra Leone
1. He aha te hiranga o AuCarb™ mō te whakawhiti o Sierra Leone ki te CIL toka mārō?
I te nekenga o te mahi keri mai i te horoinga oneone ki ngā whare keri Waro-i-te-Rohe (CIL) nui (pērā i ērā kua whakaritea mō Baomahun), he tino koi te paru toka mārō i kuruhia. He tino pakari te waro whakahohe o te AuCarb™ Coconut Shell, e ≥99% te teitei, e ārai ana i te pirau o te waro i raro i te whakaoho kaha, ā, e tiaki ana hoki i te koura kua mimitihia kia kore e mawhiti ki roto i ngā paru.
2. Pehea e United Chemical tiaki i te NaCN i te wā ua nui e ono marama te roa?
He maha ngā wā ka pāngia ngā mahi kawe uta o Sierra Leone e te paru, e te kore e taea te haere. Hei ārai i tēnei, kua mauhia ā mātou AuCyan™ NaCN ki roto i ngā paparanga maha o ngā arai polymer taumaha kua hiritia ki te wera. Ka tiakina anō ēnei e ngā pahu maitai kua whakaaetia e te UN, e ngā pouaka rakau kua whakapakaritia rānei, kia kore ai e uru te makuku ahakoa ka whakaroahia te taraka i te ua nui mō ngā wiki.
3. Ka taea e AuLeach™ GDA te whakakapi katoa i te Konutai Cyanide me te kore he whakarerekētanga tipu?
Āe, tino tika. Ko te AuLeach™ Gold Leaching Agent he whakakapinga tika mō te konutai cyanide . Ahakoa kei te whakahaere koe i tētahi pūnaha Vat Leaching, i tētahi ara iahiko CIP/CIL katoa rānei i ngā Maunga Sula, ka taea e koe te huri ki te AuLeach™ me te kore e whakapau moni ki ngā whakarerekētanga whakapaipai o te tipu, ki ngā taputapu hou rānei.
4. Ka whakapai ake a AuLeach™ i ngā wā tuku rawa i te Tauranga o Freetown?
Ae, he mea nui. Ko te whakakore i ngā matū tino paitini o te Akomanga 6.1 pēnei i te NaCN mā Freetown me tino haumaru, me ngā whakaaetanga taiao, ā, he maha ngā wā ka roa te pupuri. Nā te mea kua whakamanahia a AuLeach™ e te ao whānui he kore-morearea, ka karohia e ia ēnei tikanga matū paitini, ka taea ai te whakakore tere me te tuku tonu ki tō papa maina.
5. He aha te pānga o te whakaoranga o te ≥98.3% parakore o AuCyan™?
Ka whakaurua mai e te cyanide pokekore ngā warowaihā kore mahi me ngā matū whakapūtātanga whakarewa turanga e pau ai ō matū me te kore e tango koura. Mā te tino parakore o AuCyan™ ka whakarite kia nui rawa te cyanide kore mahi (CN-) ka tukuna ki roto i te paru, ka tere ake te memeha me te iti ake o te whakamahinga matū mō ia tana o te konganuku.
6. He aha ngā tikanga whakahaere mō te tuku taonga ki Sierra Leone?
Ko tā mātou mahi paerewa mō Āwherika ki te Hauāuru ko te CIF (Utu, Inihuarangatia, me te Uta) ki te Tauranga o Freetown . Mā mātou e whakahaere ngā tono utanga moana me te inihua moana katoa. Kia tae haumaru mai te utanga ki Freetown, ka riro i tō hoa mahi kawe utanga ā-rohe te mana whakahaere mō te whakakorenga tikanga me te kawe whakamutunga ki uta ki te wāhi kaupapa.
7. Me pēhea te āwhina a AuLeach™ ki te whakahaere i te Whare Rokiroki Para (TSF) i te wā ua nui?
I ngā wā ua nui, ka piki ake ngā taumata wai TSF, ka tūpono ai te waipuke kua poke i te cyanide. Mā te whakamahi i te AuLeach™ kore-morearea ka tino whakaiti i te paitini o tō puna paru. Ka whakaitihia tēnei i ngā tūponotanga o ngā aituā taiao, ā, ka tino whakaitihia te hiahia mō ngā tukanga tango matū utu nui.
9. He pai te AuCarb™ mō te wairewa pēhanga-teitei (HPHT)?
Āe. Ko te AuCarb™ he waro anga kokonati whakahohehia e te wera, he mea hanga ki te hanganga moroiti pai rawa atu. Ehara i te mea ka utaina teretia te koura engari ka tukuna paitia hoki i roto i ngā tukanga tango (whakarewa) pāmahana teitei me te pēhanga teitei, kia taea ai te whakahou me te whakamahi anō i tō waro mō ngā huringa maha me te kore e ngaro te mahi.
9. Me pēhea e taea ai e tā mātou tīma whakarewa o Sierra Leone te whakamātautau i ō hua?
E tino akiaki ana mātou i ngā whakamātautau pae tukutuku. Ka taea e koe te whakapā mai ki a mātou ki te tono Tauira Whakamātautau Koreutu . Ka whakarite mātou kia tukuna tika atu ngā tauira o ā mātou waro, o ngā kaihoko wai rānei ki tō taiwhanga i Sierra Leone kia taea ai e tō tīma te mahi i ā rātou ake whakamātautau hurihuri pounamu me te mimiti.
