Kungani kukhethwa i-sodium cyanide esikhundleni se-potassium cyanide ekucutshungulweni kwamaminerali?

1Izindleko - i-PriMAi-ry Factor

Esinye sezizathu ezibaluleke kakhulu zokukhetha i-Sodium cyanide ( NaCN ) kune -Potassium cyanide ( KCN ) yizindleko. I-sodium itholakala kakhulu oqweqweni loMhlaba uma iqhathaniswa ne -Potassium . Ukukhiqizwa kwe -Sodium Cyanide kuhilela izinto zokusetshenziswa ezingabizi kakhulu kanye nezinqubo zokukhiqiza ezilula.

Ama-compound e-potassium ngokuvamile adinga izinyathelo zokukhipha nokuhlanza eziyinkimbinkimbi kakhulu. Emisebenzini emikhulu yokucubungula amaminerali , edla inani elikhulu le- cyanide , umehluko wezindleko phakathi kwe -sodium cyanide ne -Potassium cyanide ungaholela ekongeni okukhulu. Isibonelo, uma imayini yegolide icubungula izinkulungwane zamathani e-ore nsuku zonke, ukusebenzisa i-Sodium cyanide ku -TEA ye- Potassium Cyanide kungonga izigidi zamaRandi minyaka yonke ezindlekweni ze-reagent.

2. umhlabathi kanye nokusabela kabusha

solubility

I-Sodium Cyanide inokuncibilika okuhle kakhulu emanzini . Uma kukhulunywa ngokucutshungulwa kwamaminerali , i -cyanide compound encibilika kakhulu ibalulekile njengoba ivumela ukwakheka okuphumelelayo kwe- Cyanide -metal complex edingekayo ekuncibilikiseni izinsimbi eziyigugu . Ezimweni ezijwayelekile, i-Sodium cyanide incibilika kalula emanzini, okuqinisekisa ukuthi ama-ion e-cyanide (CN⁻) atholakala ngobuningi obanele ukuze asabela ngegolide noma isiliva ku -ore.

I-potassium cyanide nayo iyancibilika emanzini , kodwa ukuncibilika kwe -sodium cyanide kwanele kakhulu ekucubungulweni kwezimbiwa eziningi . Akukho nzuzo ebalulekile ekusebenziseni i-potassium cyanide maqondana nokuncibilika, futhi izindleko ezengeziwe ezihambisana nayo azikuvumeli ukusetshenziswa kwayo lapho i-sodium cyanide ingenza i-ACH ibe nezinga elifanayo lokusebenza kahle ekwakheni isixazululo samanzi esidingekayo.

Ukwenza kabusha

Enkambisweni yokuncibilikisa igolide nesiliva lapho kukhona umoya-mpilo, kokubili i-sodium cyanide kanye ne-potassium cyanide kulandela i- Chemical Reaction MEC hanism efanayo. Ama-ion e-Cyanide asabela nensimbi enkambisweni ye-electrochemical, akha ama-complex e-soluble metal - cyanide. Kodwa-ke, ukusabela kwe- Sodium cyanide kufundwe kahle futhi kulungiswa kahle kuma- tin gs ezimboni.

Izinga lokusabela kwe-sodium cyanide ngegolide nesiliva ngaphansi kwezimo ezijwayelekile zokucutshungulwa kwamaminerali (i-pH cishe engu-9 - 11. ukuba khona komoya-mpilo oncibilikisiwe) kucwaningwe kabanzi, futhi amapharamitha enqubo ahlelwe kahle emashumini eminyaka. Lokhu kujwayelana kuvumela ukulawulwa okunembile kwenqubo yokukhipha , ukuqinisekisa isivuno esikhulu sokukhipha izinsimbi eziyigugu . Ukushintshela ku-potassium cyanide kungadinga ukuhlolwa kabusha kanye nokwenza ngcono lezi zimo zenqubo, okuwumzamo obizayo futhi odla isikhathi.

3. ukuzinza

I-sodium cyanide ikhombisa ukuzinza okuhle kwamakhemikhali ngaphansi kwezimo ezivame ukuhlangatshezwana nazo emisebenzini yokucubungula amaminerali . Ayiboli kalula lapho kukhona umoya, umswakama, noma ukungcola okuvamile okutholakala ema-ore. Lokhu Kuzinza kubalulekile njengoba kuqinisekisa ukuthi isixazululo se-cyanide sigcina ukusebenza kwaso ngokuhamba kwesikhathi.

Ngakolunye uhlangothi, i-potassium cyanide ingase isabela kancane ezindaweni ezithile futhi ingase ibole ngesivinini esisheshayo ngaphansi kwezimo ezithile. Isibonelo, lapho kukhona ukungcola okuthile kwe-acidic e-ore noma ezindaweni ezinomswakama ophezulu wensimbi , i-potassium cyanide ingase ithambekele kakhulu ekufakweni kwe-hydrolysis noma kwezinye izindlela zokubola, okuzonciphisa ukugcwala kwama -ion e-cyanide atholakalayo futhi ngaleyo ndlela kusebenze kahle inqubo yokukhipha i-Precious Metal.

4. ukuphatha futhi ukuphepha Ukubhekelwa

Kokubili i-sodium cyanide kanye ne-potassium cyanide kuyizinto ezinobuthi obukhulu . Kodwa-ke, ngenxa yokusetshenziswa kabanzi kwe-sodium cyanide embonini , kunezinqubo zokuphepha ezisungulwe kahle kanye nezinqubo zokuphatha . Izisebenzi ezitshalweni zokucubungula amaminerali ziqeqeshwe ukuphatha i-sodium cyanide ngokuphephile , futhi imishini esetshenziselwa ukugcina , ukuThutha , kanye nokusetshenziswa kwe-sodium cyanide yaklanywa kucatshangelwa ukuphepha.

Imboni ithuthukise Izindlela Zokuphepha eziphelele ze-sodium cyanide, njengezinhlelo zokungenisa umoya ezifanele ezindaweni zokucubungula, Izidingo Zemishini Yokuzivikela Yomuntu Siqu , kanye nezinhlelo Zokuphendula Eziphuthumayo uma kwenzeka kuchitheka noma kuvuza. Ukushintshela ku-potassium cyanide kuzodinga ukuqeqesha kabusha abasebenzi futhi mhlawumbe kuguqulwe ingqalasizinda yokuphepha esitshalweni, okwengeza ungqimba olungadingekile lobunzima kanye nezindleko.

Ekuphetheni, ukukhetha i-sodium cyanide kune-potassium cyanide ekucutshungulweni kwamaminerali kuyisinqumo esinengqondo Ngokusekelwe ezicini zezomnotho, zamakhemikhali, kanye nezokuphepha. Izindleko eziphansi, ukuncibilika okufanele kanye nokusebenza kabusha, ukuzinza okuhle, kanye nezinqubo zokuphepha ezisungulwe ezihambisana ne-sodium cyanide kwenza kube yindlela ekhethwayo yokukhipha izinsimbi eziyigugu kuma-ore.
