IGold Pool Leaching Method: Umda oSebenzayo kunye nokuHamba kweNkqubo

Indlela yokukhupha amanzi echibini legolide yaziwa ngokulula kwayo, utyalo-mali oluphantsi lwezixhobo, kunye nokusebenza kakuhle kweendleko, okuvumela ukuqalisa imveliso ngokukhawuleza. Nangona kunjalo, le ndlela ifuna indawo enkulu njengoko kufuneka amachibi amaninzi ukuze kugqitywe umsebenzi wokukhupha amanzi. Ngaphezu koko, ayifanelekanga kuzo zonke iintlobo zegolide. Eli nqaku liza kwazisa umda ofanelekileyo, ukuhamba kwenkqubo yendlela yokukhupha amanzi echibini legolide, kunye nemeko yesicelo esisebenzayo.

Umda osebenzayo weNdlela yokuLeaching yePool yeGolide

Intsimbi ekrwada yegolide elungele indlela yokuvuza echibini kufuneka ihlangabezane neendlela ezintathu ngaxeshanye. Okokuqala, iinqununu zegolide kufuneka zibe nobukhulu obuhle bokusabalalisa. Okwesibini, intsimbi ekrwada kufuneka ibe yeyomgangatho ophantsi okanye inqanaba eliphezulu kakhulu. Okwesithathu, intsimbi ekrwada ngokwayo kufuneka ingakwazi ukungena kakuhle. Umzekelo, i-iron oxide cap - uhlobo lwe-ores oluqulethe igolide ecocekileyo kunye ne-oxidized quartz vein ores enegolide ecolekileyo ifaneleke kakhulu kwindlela yokucoca ichibi.

Ireyithi yokufumana inzuzo yendlela yokuvuza echibini inokufikelela kuma-70 - 90%. Xa kuthelekiswa ne-CIL kunye ne-CIP iindlela zokutsalwa kwegolide, indlela yokukhupha i-pool ibonakalisa iindleko eziphantsi, iyenza ibe sisisombululo esisebenzayo sokuphucula uqoqosho lwe-ores yegolide yomgangatho ophantsi. Ukongezelela, ukusebenza kwayo okulula kukhokelela ekunciphiseni iindleko zabasebenzi. Nangona kunjalo, indlela yokuphuma emanzini ingenisa iindleko eziphezulu zokwakhiwa kwangaphambili kwaye ifuna ixesha elide lokuvuza. Oku kungenxa yokuba kuyimfuneko ukwakhiwa kwamachibi avuzayo kunye namachibi angamanzi angamanzi, ukuqinisekisa ukuba ayavuza - angqineke kwaye omile. Emva koko, intsimbi ekrwada ifakwa kwidama le-leaching, kwaye isisombululo se-leaching silungiswa kwi-pool elulwelo oluyinkqantosi ngaphambi kokuba lufakwe kwi-leaching pool ukuze ihlanjululwe. Emva kwexesha elithile, isisombululo esikhulelweyo sikhutshwa ngenxa yokufuduka.

Ukuqukuqela kweNkqubo yeNdlela yeGold Pool Leaching

Ukuvuza kwephuli yegolide ngokuqhelekileyo kwenzeka kwiitanki zokuvuza. La matanki anokwenziwa ngamaplanga, imikhombe yentsimbi, okanye ngesamente. Umzantsi wetanki unokuba tyaba okanye uthambekele kancinane, kwaye banokuba setyhula, uxande, okanye isikwere ngokwemilo. Ngaphakathi kwetanki, i-bottom yobuxoki eyenziwe nge-asidi ene-perforated - iipleyiti ezixhathisayo zifakwe. Ilaphu lokucoca libekwe phantsi kobuxoki, kwaye igridi eyenziwe ngamaplanga okanye i-corrosion - imicu yetsimbi enganyangekiyo ibekwe phezu kwelaphu lokucoca. Ngethuba le-leaching, i-ore ilayishwa kwi-tank, kwaye i-agent agent yongezwa ukusuka phezulu. Isisombululo se-leaching siphuma siphuma phantsi kwezantsi lobuxoki. Umzantsi ongeyonyani usebenzela ukuhluza nokuxhasa intsimbi ekrwada.

Ukuhamba kwenkqubo yokukhuhla ichibi kulandelayo: I-ore ethwele igolide etyunyuziweyo ukuya kubukhulu obuthile besuntswana ifakwa kwitanki yokukhuhla. Isisombululo se-alkaline cyanide songezwa ukuze kukhuhlwe, apho igolide inyibilikiswa kwisisombululo. Emva kokukhuhla ixesha elithile, xa uxinzelelo kunye nomgangatho wolwelo zihlangabezana neemfuno njengoko zifunyenwe, isisombululo se-gold-bearing (isisombululo esikhulelweyo) sikhutshwa ezantsi kwitanki. Igolide ifunyanwa ngokufuduswa ngee-zinc flakes (umgubo) (i-activated Carbon adsorption nayo ingasetyenziswa). Intsalela yokukhuhla ifakwa kunyango lokucoca ngaphambi kokuba ilahlwe. Ukususa i-cyanide kwintsalela yokukhuhla, izinto ezifana ne-sodium bisulfite kunye ne-copper sulfate zingongezwa.

Kufuneka kuqatshelwe ukuba ixesha elifunekayo kwi-tank ye-percolation leaching ayixhomekanga kuphela kwizinga lokuchithwa kwe-solvent kwi-minerals kodwa nakwizinga lokungena kwe-solvent ngokusebenzisa umaleko wezinto eziphathekayo. Izinga lokungena ikakhulu lixhomekeke kwizinto ezifana nobude bezinto ezilayishiweyo, i-porosity yempahla, iqondo lomxholo wentlenga, i-viscosity ye-agent leaching, kunye neempawu zendalo zemathiriyeli ngokwayo.
