Ukoyisa Imingeni ye-VMS Ore kwiPhondo le-Afrika: IiReagents zeGolide eziPhambili ze-Eritrea
I-Eritrea iqinisa ngokukhawuleza isikhundla sayo njengendlu enamandla kwicandelo lezemigodi kwiPhondo le-Afrika. Ngemisebenzi ekumgangatho wehlabathi efana nomgodi weBisha polymetallic (i-zinc-copper-gold-silver) kunye ne-Koka gold deposit (iZara Mining Share Company), ubutyebi bejoloji yelizwe abunakuphikiswa. Nangona kunjalo, i-metallurgy yase-Eritrea ayinazo iingxaki zobugcisa ezigqithisileyo. Ii-volcanogenic Massive Sulfide (VMS) deposits eziphambili kunye nokusingqongileyo okungqongqo kwengingqi zifuna izisombululo zeekhemikhali ezikhethekileyo kakhulu.
Iingcali zesinyithi ezisebenza e-Eritrea zijongene nemingeni emithathu eyahlukileyo nenzima. Okokuqala, i-mineralology: Iidipozithi ze-VMS zidume ngokugxila okuphezulu kwe-copper kunye ne-zinc enyibilikayo. Ezi zinyithi zesibini zisebenza njenge-"cyanicides" ezinamandla, zitya izixa ezininzi zeSodium Cyanide ngaphambi kokuba igolide ikhutshwe, zifutha kakhulu i-OPEX. Okwesibini, imida yokusingqongileyo: Imozulu eyomileyo yase-Eritrea ithetha ukuba amanzi axabisekile. I-Eritrean National Mining Corporation (ENAMCO) inyanzelisa imigaqo-nkqubo enzima engenabungozi malunga neZixhobo zokugcina iiTailings (TSF) ukukhusela amanzi angaphantsi komhlaba anqabileyo. Okwesithathu, ukuhanjiswa kwempahla eLwandle oluBomvu: Impahla efika kwiPort of Massawa ijongene namaqondo obushushu asehlotyeni angaphezulu kwama-45°C. Uthutho olulandelayo oluya ngaphakathi elizweni olunqumla umhlaba oqinileyo, onentaba ukuya kwiindawo zeemigodi ezikude lufuna ukupakishwa kweekhemikhali okungenakutshatyalaliswa kwaye okumelana nobushushu kakhulu.
United Chemical iyile ipotifoliyo ethile yee-reagents zokukhupha igolide ukuze yoyise le mingeni yase-Eritrea. Ngokunciphisa ukuphazamiseka kwesinyithi esisisiseko, ukuqinisekisa uthutho oluphezulu, kunye nokubonelela ngezinye iindlela ezihambelana nendalo, sixhobisa umzi-mveliso wakho ukuba ufikelele kumanqanaba aphezulu okubuyisela ngelixa unciphisa kakhulu ukusetyenziswa kweekhemikhali iyonke.
