intshayelelo

Kwi Imveliso yegolide ishishini, i Inkqubo ye-cyanidation isetyenziselwa kakhulu ukukhupha igolide kwintsimbi ekrwada. Isodium i-cyanide idlala indima ebalulekileyo kule nkqubo njengoko isenza i-complex enyibilikayo enegolide, evumela ukwahlulwa kwayo kwi-ore matrix. Nangona kunjalo, ukugxila kwe Isodium cyanide kwisisombululo se-leaching kuchaphazela kakhulu ukusebenza kakuhle kokukhutshwa kwegolide, kunye nokusingqongileyo kunye nemiba yokhuseleko. Ukubeka iliso nolawulo oluchanekileyo Isodium cyanide Ugxininiso lubalulekile ekuphuculeni inkqubo yokuvelisa igolide.

Ukubaluleka kweSodium Cyanide Concentration kwiMveliso yeGolide

Impembelelo kwi-Gold Extraction Efficiency

Ugxininiso olufanelekileyo lwe sodium cyanide iqinisekisa ukuba ukusabela phakathi kwegolide kunye ne-sodium cyanide phambi kwe-oksijini ihamba ngokufanelekileyo. Ukuba uxinaniso luphantsi kakhulu, izinga lokunyibilika kwegolide liya kucotha, nto leyo ekhokelela ekutsalweni okungaphelelanga kunye namazinga asezantsi okubuyisela igolide. Ngakolunye uhlangothi, ukuxinana okuphezulu kakhulu kwe-sodium cyanide kunokukhokelela ekusetyenzisweni ngokungeyomfuneko kwee-reagents, ukunyuka kweendleko, kunye nobungozi obunokuthi bube khona. Ngokubanzi, eyona nto iphezulu yesodium cyanide kwisisombululo se-leaching imiselwa ngophando lovavanyo kunye nokusebenza kwemveliso, ngokuqhelekileyo ngaphakathi koluhlu lwe-0.03% - 0.15% kwiimeko ezininzi.

Iingqwalasela zokusiNgqongileyo noKhuseleko

Isodium cyanide yinto enetyhefu kakhulu. Kwinkqubo yokuvelisa igolide, nakuphi na ukuvuza okanye ukulahlwa okungafanelekanga kwezisombululo eziqulethe i-sodium cyanide kunokubangela ukungcoliseka okukhulu kwendalo kwaye kubeke engozini impilo kunye nokhuseleko lwabasebenzi kunye noluntu. Ulawulo oluchanekileyo lokugxininiswa kwayo kunceda ukunciphisa inani le-cyanide elisetyenzisiweyo, ukunciphisa umngcipheko wokuvuza kunye nomthwalo kunyango olulandelayo lwamanzi amdaka. Ngokomzekelo, ekulawuleni i-tailings yemigodi yegolide, kuyimfuneko ukuqinisekisa ukuba i-cyanide concentration kwi-tailings iyancitshiswa kwinqanaba elikhuselekileyo ngokusebenzisa iindlela ezifanelekileyo zonyango. E-China, umgangatho ufuna ukuba i-cyanide concentration kwi-tailings kufuneka ibe ngaphantsi kwe-0.2 mg / L.

Nangona kunjalo, le ndlela ifuna iisampulu kwisiza, ilandelwa yilabhoratri yonyango olusekwe kwisampulu kunye ne-titration. Inkqubo ithatha ixesha, kwaye kukho ixesha phakathi kwesampuli kunye nokufumana iziphumo, ezinokuthi zingakwazi ukunika isikhokelo sexesha lokwenyani kwinkqubo yemveliso.

Indlela yoMbala

Indlela ye-colorimetric isebenzisa ukusabela kwee-ion ze-cyanide kunye ne-reagents ezithile ukuvelisa imveliso enemibala. Ukuqina kombala kuhambelana nokuxinwa kweeyoni ze-cyanide. Ngokomzekelo, iphepha lokuvavanya i-cyanide eliphuhliswe nguBeijing Jinsuokun lisekelwe kulo mgaqo. Iphepha lokuvavanya liqulethe isalathisi esibonakalisa i-cyanide ions kwiqondo lokushisa ukuze utshintshe umbala. Ngokuthelekisa umbala wephepha lokuvavanya emva kokucwiliswa kwisisombululo sesampuli kunye nombala oqhelekileyo - ikhadi lokuthelekisa, ukuxinwa kwee-ion cyanide kwisisombululo kunokugqitywa ngokukhawuleza. Le ndlela ineenzuzo zomthamo omncinci, ukuthwala, ukulungeleka, ixabiso eliphantsi, kunye nokuvavanya ngokukhawuleza. Ikulungele ukubeka esweni ukuxinana kwe-cyanide kwizisombululo zokuvuza, izisombululo zentsalela yeentsalela zezimbiwa, kunye nezinye izisombululo kwiinkqubo zokuvelisa umgodi wegolide ezinje ngemfumba evuzayo, ukuvuzwa kwetanki, kunye ne-ore cyanidation epheleleyo. Uluhlu logxininiso olusebenzayo lwephepha lovavanyo ngokubanzi luyi-0.01% - 1.0%, enokuthi ihlangabezane neemfuno zeziganeko ezininzi zemveliso yegolide.

Iindlela zeSpectroscopic

Iindlela ze-Spectroscopic ezifana ne-ultraviolet - i-spectroscopy ebonakalayo kunye ne-ion - i-electrode spectroscopy ekhethiweyo ingasetyenziselwa ukubeka esweni ukuxinana kwe-sodium cyanide. I-Ultraviolet - i-spectroscopy ebonakalayo ilinganisa ukutsalwa kwesisombululo sesampulu kwi-wavelength ethile. Ekubeni i-cyanide-equlethe ii-complexes zineempawu zokufunxa kwi-ultraviolet - indawo ebonakalayo, ukuxinwa kwe-cyanide kunokumiselwa ngokuseka i-curve calibration. Ion - i-electrode ekhethiweyo ye-spectroscopy isebenzisa i-ion - i-electrode ekhethiweyo ekhethekileyo kwiiyoni ze-cyanide. Xa i-electrode ibhaptizwa kwisisombululo sesampuli, umahluko onokuthi uveliswe ngenxa yempendulo ekhethiweyo ye-electrode kwi-ion cyanide, kwaye ukuxinwa kweeyoni ze-cyanide zingabalwa ngokufanelekileyo. Ezi ndlela ze-spectroscopic zikhawuleza, zichanekile, kwaye zingasetyenziselwa ukubeka iliso kwi-intanethi kwinkqubo yemveliso.

Izicwangciso-qhinga zokuLawula iSodium Cyanide Concentration

UkuPhuculwa kweNkqubo yokuLeaching

Uhlengahlengiso lweNkqubo yokuLeaching

Kwinkqubo ye-leaching, izinto ezifana nexabiso le-pH yesisombululo, ubushushu, kunye nesantya se-aeration nazo zichaphazela ukusabela phakathi kwe-sodium cyanide kunye negolide. Ngokomzekelo, ukugcina ixabiso le-pH yesisombululo se-leaching kuluhlu lwe-10 - 11 kunokuqinisekisa ukuzinza kweeyoni ze-cyanide, ukuthintela ukubola kwe-cyanide kwigesi enetyhefu ye-hydrogen cyanide, kunye nokukhuthaza ukuchithwa kwegolide. Ubushushu besisombululo se-leaching ngokubanzi kunempembelelo kwireyithi yokusabela. Nangona ukwandisa ubushushu kunokukhawulezisa ukusabela, kukwanyusa ukusetyenziswa kwe-sodium cyanide kwaye kunokubangela ezinye iimpendulo ezisecaleni. Ngoko ke, kuyimfuneko ukumisela ubushushu obufanelekileyo ngokusebenzisa imifuniselo. Ukongezelela, i-aeration eyaneleyo inokubonelela nge-oksijini efunekayo ekuphenduleni, kodwa ukugqithiswa kwe-aeration ngokugqithiseleyo kunokukhokelela kwi-oxidation yezinye izinto kwisisombululo kunye nokuchaphazela umphumo we-leaching. Ngokuphucula ngokubanzi le miba kwinkqubo yokuvuza, ukuxinwa kwe-sodium cyanide kunokulawulwa ngokufanelekileyo phakathi koluhlu olufanelekileyo.

Ukulawulwa kweXesha leLeaching

Ixesha le-leaching lihambelana ngokusondeleyo noxinzelelo lwe-sodium cyanide. Kwinqanaba lokuqala le-leaching, i-concentration ye-sodium cyanide iphezulu kakhulu ukuqinisekisa ukuba isantya sokuphendula ngokukhawuleza. Njengoko inkqubo yokucoca iqhubela phambili, ukuxinwa kwe-sodium cyanide kuncipha ngokuthe ngcembe. Ngokulawula ngokuchanekileyo ixesha le-leaching, kunokwenzeka ukuqinisekisa ukuba igolide iyachithwa ngokupheleleyo ngelixa inciphisa ukusetyenziswa okungadingekile kwe-sodium cyanide. Ukumiselwa kwexesha lokucoca kufuneka kuthathelwe ingqalelo izinto ezifana nobume be-ore, ubungakanani besuntswana le-ore, kunye noxinzelelo lokuqala lwe-sodium cyanide. Umzekelo, kwii-ores ezinomxholo ophezulu wegolide kunye ne-cyanide efanelekileyo - iipropati zokucoca, ixesha elifutshane lokucoca linokwanela; ngelixa kwii-ores ezintsonkothileyo, ixesha elide lokucoca linokufuneka.
