Ezona zinto ziluncedo kwiSodium Cyanide Heap Leaching kwiGold Extraction

Ukucocwa kwe -sodium cyanide heap leaching yindlela esetyenziswa kakhulu kwishishini lemigodi yegolide ekukhupheni igolide kwi-ore ezikumgangatho ophantsi. Le nkqubo ibandakanya ukuqokelela i-ore zegolide ezikumgangatho ophantsi okanye i-flotation tailings kwi-pad material kunye nokutshiza isisombululo se-cyanide phezu kwe-heap ukuze kunyibilikiswe igolide nesilivere, kwenze isisombululo esinegolide sokubuyiselwa emva koko. Nazi iingenelo eziphambili zale ndlela:

Iindleko - ukusebenza kakuhle

1. Utyalo-mali oluphantsi: Enye yezona nzuzo zibalulekileyo ze- Sodium cyanide heap leaching kukufuna kwayo imali encinci. Xa kuthelekiswa neendlela ezintsonkothileyo zokukhupha igolide ezifana nokusila nokunyibilikisa igolide ngokwesiko, ezifuna iziseko zophuhliso nezixhobo ezinkulu, i-heap leaching ifuna kuphela izixhobo ezisisiseko ezifana ne-leaching pad, inkqubo yokuqokelela isisombululo, kunye neendlela zokujikeleza isisombululo. Akukho mfuneko yokwakha izityalo ezinkulu nezibizayo zokucubungula, nto leyo eyenza ukuba ibe lukhetho olunomtsalane, ngakumbi kwimisebenzi yokwemba emincinci ukuya kwephakathi okanye kwiindawo zokwemba ezinemithombo embalwa.

2.Ukunciphisa iindleko zokusebenza:

• Ukusetyenziswa kwamandla aphantsi: Inkqubo yokukhupha i-heap leaching inemfuno ephantsi yamandla. Ayibandakanyi imisebenzi enamandla kakhulu efana nokugaya i-ore ibe ngumgubo ocolekileyo kwi-ball mill, into eqhelekileyo kwezinye iindlela zokukhupha. Ukusebenza okulula kokutshiza isisombululo kunye nokugqobhoza i-ore heap kufuna amandla amancinci kakhulu, nto leyo ekhokelela ekunciphiseni iindleko zamandla.

• Iindleko eziphantsi ze-reagent (xa kuthelekiswa nezinye iindlela): Nangona i-cyanide iyi-reagent ephambili kwaye ukuphathwa kwayo kufuna amanyathelo angqongqo okhuseleko, ngokwenkqubo yokukhupha igolide iyonke, ubungakanani be-cyanide efunekayo ekukhupheni igolide bunokulungiswa. Xa kuthelekiswa nezinye ii-agents ezikhupha igolide, i-cyanide inokusebenza kakuhle kwiimeko ezithile, ingakumbi xa ucinga ngomthamo omkhulu wee-ore ezikumgangatho ophantsi ezinokucutshungulwa kusetyenziswa le ndlela.

Ukufaneleka kwe-ores yomgangatho ophantsi

1. Ukukhupha ngokwezoqoqosho kwiidiphozithi ezikumgangatho ophantsi: Ukukhupha i-sodium cyanide heap leaching kulungele kakhulu ukunyanga ii-ore zegolide ezikumgangatho ophantsi, ngokuqhelekileyo ezo zinemigangatho ephakathi kwe-0.5 - 3g/t. Oku kuye kwandisa kakhulu uluhlu lwezixhobo zegolide ezisebenza kakuhle ngokwezoqoqosho. Ngaphambili, iidiphozithi ezininzi ezikumgangatho ophantsi zazithathwa njengezingenaxabiso ukumbiwa. Nangona kunjalo, ngophuhliso lwetekhnoloji yokukhupha i-heap leaching, ezi diphozithi ngoku zingasetyenziswa ngenzuzo. Umzekelo, kwezinye iindawo apho iidiphozithi zegolide ezinkulu nezikumgangatho ophezulu zinqabile, ukukhupha igolide kwii-ore ezikumgangatho ophantsi ngokusebenzisa i-heap leaching kuye kwaba ngumthombo omkhulu wemveliso yegolide.

2. Ukusetyenziswa kwezixhobo ezingasetyenziswanga ngaphambili: Kuvumela ukusetyenziswa kweentlobo ngeentlobo zezixhobo ezingasetyenziswanga ngaphambili, ezifana nezinto ezilahliweyo zemigodi, kuquka neentsalela zemisebenzi yokwemba yangaphambili kunye neentsimbi ezikumgangatho ophantsi ezashiywa ngexesha lenkqubo yokwemba. Ngokusebenzisa ezi zinto, igolide eyongezelelweyo ayinakufunyanwa kuphela, kodwa ikwanceda ekunciphiseni umngcipheko wokusingqongileyo onxulunyaniswa nokugcinwa kwenkunkuma eninzi.

Inkqubo elula

1. Ukulula kokusebenza: Inkqubo yokukhupha i-heap ilula kakhulu ekusebenzeni kwayo. Nje ukuba i-ore pile yakhiwe kwi-leaching pad elungiselelwe kakuhle, umsebenzi ophambili ubandakanya ukutshiza rhoqo isisombululo se-cyanide phezu kwe-heap. Le nkqubo ayifuni basebenzi abanobuchule obuphezulu kwimisebenzi yemihla ngemihla. Abasebenzi banokuqeqeshwa ngokukhawuleza ukwenza imisebenzi efana nokutshiza isisombululo, ukujonga amazinga okuhamba kwesisombululo, kunye nokuqokelela iisampulu. Olu lula lukwanegalelo ekunciphiseni iindleko zomsebenzi ezinxulumene noqeqesho kunye nokuqesha abasebenzi abanolwazi oluphezulu.

2. Amanyathelo okucubungula ambalwa: Xa kuthelekiswa neenkqubo zokukhupha igolide ezintsonkothileyo, ukucocwa kwe-heap kuneendlela ezimbalwa zokucubungula. Akukho mfuneko yeenkqubo zokwahlula izimbiwa ezintsonkothileyo ezifana nokuqunjelwa kwefroth, okubandakanya amanyathelo amaninzi okongeza ii-reagents ezahlukeneyo ukwahlula izimbiwa ezithwele igolide kwi-gangue minerals. Kwi-heap leaching, isisombululo se-cyanide siqhagamshelana ngqo ne-ore ekwi-heap, sinyibilikise igolide nesilivere, nto leyo eyenza kube lula inkqubo yokukhupha iyonke.

Inkqubela phambili yezobuchwephesha iphucula impumelelo

1. Iindlela zokudibanisa eziphuculweyo: Uphuhliso lweendlela zokudibanisa eziphuculweyo luye lwaphucula kakhulu ukusebenza kwe -Sodium cyanide heap leaching . Kwiintsimbi ezingenanto yokungena kakuhle okanye umxholo wodongwe ophezulu, i-agglomeration ingasetyenziselwa ukuphucula ukuhamba kwesisombululo se-cyanide kwi-ore heap. Ngokongeza izibophelelo ezifana nelayimu okanye isamente yasePortland kwi-ore uze emva koko umanzise kwaye udibanise umxube ngoomatshini, ukwakheka kweendlela zokuxuba isisombululo kuyakhuthazwa. Oku kuphumela ekunxibelelaneni okusebenzayo phakathi kwesisombululo se-cyanide kunye neeminerali ezinegolide, okukhokelela ekunyukeni kwamazinga okubuyisa igolide.

2. Ukusetyenziswa kwezongezo ukuphucula ukuvuza: Ukongezwa kwezongezo ezithile kunokuphucula ngakumbi inkqubo yokuvuza. Umzekelo, ukusetyenziswa kwee-agents ezikhupha ioksijini ezifana ne-oxygen ecocekileyo okanye i-calcium peroxide kunokunyusa amandla okuvundisa isisombululo sokuvuza, kuphucule ukunyibilika kwegolide. Ukongeza, ii-agents ezisebenzayo kumphezulu zingongezwa ukuphucula ukumanzisa kwamasuntswana e-ore yisisombululo se-cyanide, kuphucule ukusebenza kakuhle kokuvuza. Olu phuculo lwetekhnoloji lwenze ukuvuza kwe -Sodium Cyanide heap kusebenza ngakumbi kwaye kusebenze ngakumbi ekukhupheni igolide kwiintlobo ezahlukeneyo zee-ore.
