Kwicandelo lemigodi yanamhlanje, iHeap Leaching ivele njengendlela eyamkelweyo ngokubanzi nengabizi kakhulu yokukhupha igolide kwiintsimbi ezikumgangatho ophantsi. Phakathi kwezinto ezahlukeneyo zale nkqubo, iCyanide , ngakumbi iSodium Cyanide (NaCN), idlala indima ebalulekileyo.
Ukubaluleka kweSodium Cyanide kwi-Gold Extraction
Izibalo zibonisa ukuba i-sodium cyanide isetyenziswa kwiinkqubo zokuNcitshiswa kweGolide ezingaphezu kwama-80% . Eli zinga liphezulu lokusetyenziswa ligxininisa ukubaluleka kwayo kwishishini lezemigodi. Umzekelo, kwimigodi eTanzania, emva kokungeniswa kwe- Sodium cyanide njenge-leaching agent, kwabonwa uphuculo oluphawulekayo. Izinga lokubuyiswa kwe-ore dressing landa ukusuka kwi-60% yokuqala ukuya kwi-85%, kwaye imveliso nayo yanda kakhulu. La manani awabonisi nje kuphela ukusebenza kwe-sodium cyanide kwinkqubo yokuphucula kodwa akwabonisa indima yayo ebalulekileyo ekuphuculeni amazinga okubuyiswa kwegolide kunye nobungakanani bemveliso.
Inkqubo yeSodium Cyanide kwi-Heap Leaching
Kwinkqubo yokukhutshwa kwemfumba, iintsimbi ezikrwada zegolide zodidi oluphantsi okanye iintsalela zezimbiwa ezidadayo zifunjwa kwiphedi eyakhiwe ngokukodwa engenakungeneka. Emva koko, isisombululo se-sodium cyanide sitshizwa phezu kwemfumba ye-ore ngendlela ye-cyclic. Phambi kweoksijini (ngokuqhelekileyo ivela emoyeni), i-sodium cyanide isabela kunye negolide kwi-ore. Ukusabela kweekhemikhali kunokubonakaliswa ngokubanzi ngolu hlobo lulandelayo: 4Au + 8NaCN + O₂+ 2H₂O = 4Na[Au(CN)₂]+ 4NaOH. Ngale ndlela yokusabela, igolide yenza i-soluble complex, i-sodium aurocyanide (Na[Au(CN)₂]), ethi emva koko inyibilike kwisisombululo kwaye inokuphinda ihlawulwe.
Izinto eziluncedo zokusebenzisa iSodium Cyanide kwimfumba yokuLeaching
Ukusebenza Kakhulu : Njengoko kubonisiwe kumzekelo wemigodi yaseTanzania, i-sodium cyanide inokunyibilikisa igolide kwii-ore, nto leyo ekhokelela ekwandeni okukhulu kwesantya sokubuyiselwa. Olu buchule buphezulu ekukhupheni igolide kwii-ore ezikumgangatho ophantsi lwenza ukuba i-heap leaching ene-sodium cyanide ibe lukhetho olufanelekileyo kwimigodi ebingathathwa njengengenaxabiso.
Ukusebenza kakuhle kweendleko : Xa kuthelekiswa nezinye iindlela zokukhupha igolide, ukusetyenziswa kwe-sodium cyanide ekukhupheni igolide kubiza kancinci. Ixabiso lilonke lenkqubo yokukhupha igolide, kuquka nexabiso le-sodium cyanide, lidla ngokuba liphantsi kuneendlela zokukhupha ezintsonkothileyo nezisebenzisa amandla amaninzi. Oku kusebenza kakuhle kweendleko yinto ephambili enegalelo ekusetyenzisweni kwayo ngokubanzi kwishishini lezemigodi.
Imingeni kunye neZilumkiso ezinxulumene neSodium Cyanide
Ubuthi : I-sodium cyanide inobungozi kakhulu. Nakuphi na ukuvuza okanye ukuphathwa kakubi kwesisombululo se-cyanide kunokuba yingozi enkulu kwindalo nakwimpilo yabantu. Ke ngoko, amanyathelo okhuseleko angqongqo kunye neenkqubo zokukhusela indalo kufuneka zibekho ngexesha lokugcina, ukuthuthwa, kunye nokusetyenziswa kwe-sodium cyanide. Imigodi kufuneka ibe neenkqubo zokuqulatha eziyilwe kakuhle ukuthintela ukuchitheka kwe-cyanide kunye neendlela ezisebenzayo zonyango lwezisombululo zenkunkuma ezine-cyanide.
Ukuthobela Imithetho : Ngenxa yobuthi bayo, ukusetyenziswa kwe-sodium cyanide kuxhomekeke kwimigaqo engqongqo kumazwe amaninzi. Iinkampani zemigodi kufuneka zithobele le migaqo malunga nokugcinwa, ukuphathwa, kunye nokulahlwa kwe-cyanide. Oku kuquka ukujonga rhoqo amanqanaba e-cyanide kwinkunkuma engcolileyo kunye nokuqinisekisa ukuba iyahlangabezana nemigangatho evumelekileyo yokusingqongileyo.
Ukuqukumbela, i-sodium cyanide sisixhobo esiyimfuneko kwinkqubo yokukhutshwa kwemfumba yemigodi yegolide. Ukusebenza kwayo okuphezulu kunye neendleko - ukusebenza kakuhle kwenza kube yinto ekhethwayo yokukhupha igolide kwi-ores yomgangatho ophantsi. Nangona kunjalo, ubutyhefu obunxulumeneyo kunye neemfuno zolawulo zifuna ukuphathwa ngononophelo kunye nothotyelo olungqongqo ukuze kuqinisekiswe ukusebenza kwemigodi ezinzileyo nekhuselekileyo.
