Kutheni kukhethwe i-sodium cyanide endaweni ye-potassium cyanide kwi-mineral processing?

1. Iindleko - iFactor Primary

Esinye sezizathu ezibalulekileyo zokukhetha Isodium cyanide (NaCN) ngaphezulu Potassium cyanide (KCN) lixabiso. Isodium ininzi kakhulu kuqweqwe loMhlaba xa kuthelekiswa ne potassium. Imveliso ye Isodium cyanide ibandakanya imathiriyeli ekrwada engabizi kakhulu kunye neenkqubo ezilula zokuvelisa.

Iikhompawundi zePotassium ngokubanzi zifuna amanyathelo anzima ngakumbi okutsalwa kunye nokucoca. Ngomlinganiselo omkhulu Ukulungiswa kwezimbiwa imisebenzi, edla izixa ezikhulu ze i-cyanide, umahluko weendleko phakathi sodium cyanide kunye ne-potassium cyanide inokuguqulela kugcino olubalulekileyo. Umzekelo, ukuba umgodi wegolide usebenza amawaka eetoni zentsimbi mihla le, ukusebenzisa i-sodium cyanide endaweni ye-potassium cyanide kunokonga izigidi zeerandi ngonyaka kwiindleko ze-reagent.

2. Ukunyibilika kunye nokuSebenza kwakhona

Umzimba

Isodium cyanide inonyibiliko olugqwesileyo emanzini. Kumxholo wokusetyenzwa kwezimbiwa, ikhompawundi ye-cyanide enyibilikayo kakhulu ibalulekile njengoko ivumela ukwenziwa ngokufanelekileyo kwe-cyanide - i-metal complex eyimfuneko ekunyibilikiseni isinyithi esixabisekileyo. Kwiimeko eziqhelekileyo, i-sodium cyanide iyachithwa ngokukhawuleza emanzini, iqinisekisa ukuba i-cyanide ions (CN⁻) ifumaneka kwi-concentration eyaneleyo yokusabela ngegolide okanye isilivere kwi-ore.

I-Potassium cyanide nayo iyanyibilika emanzini, kodwa ukunyibilika kwe-sodium cyanide kungaphezulu kokwaneleyo kwizicelo ezininzi zokusetyenzwa kwezimbiwa. Akukho nzuzo ebalulekileyo ekusebenziseni i-potassium cyanide ngokubhekiselele kwi-solubility, kwaye iindleko ezongezelelweyo ezihambelana nayo azichazi ukusetyenziswa kwayo xa i-sodium cyanide inokufikelela kwinqanaba elifanayo lokuphumelela ekwenzeni izisombululo ezifunekayo zamanzi.

Ukuphinda usebenze

Kwinkqubo yokunyibilikisa igolide nesilivere phambi kweoksijini, zombini i-sodium cyanide kunye ne-potassium cyanide zilandela indlela efanayo yokusabela kweekhemikhali. Iiyoni ze-cyanide zisabela ngesinyithi kwinkqubo ye-electrochemical, zenza isinyithi esinyibilikayo - i-cyanide complexes. Nangona kunjalo, i-reactivity ye-sodium cyanide ifundwe kakuhle kwaye iphuculwe kwiindawo zoshishino.

Ireyithi yokusabela ye-sodium cyanide ngegolide kunye nesilivere phantsi kweemeko eziqhelekileyo zokusetyenzwa kweeminerali (pH malunga ne-9 - 11. ubukho be-oksijini enyibilikisiweyo) iye yaphandwa kakhulu, kwaye iiparameters zenkqubo ziye zalungiswa - zilungelelaniswa kumashumi eminyaka. Oku kuqhelana kuvumela ulawulo oluchanekileyo ngakumbi lwenkqubo ye-leaching, ukuqinisekisa izivuno eziphezulu zokutsalwa kweentsimbi ezixabisekileyo. Ukutshintshela kwi-potassium cyanide kuya kufuna ukuphononongwa kwakhona kunye nokubanakho ukuphinda kuphuculwe iimeko zenkqubo, nto leyo ebiza imali eninzi kwaye itya ixesha.

3. Uzinzo

I-sodium cyanide ibonisa uzinzo oluhle lweekhemikhali phantsi kweemeko eziqhelekileyo ezidibana nazo kwimisebenzi yokucubungula izimbiwa. Ayiboli lula xa kukho umoya, ukufuma, okanye ukungcola okuqhelekileyo okufumaneka kwintsimbi ekrwada. Olu uzinzo lubalulekile njengoko luqinisekisa ukuba isisombululo secyanide sigcina ukusebenza kwaso ekuhambeni kwexesha.

I-Potassium cyanide, kwelinye icala, inokuphinda isebenze kancinci kwiindawo ezithile kwaye inokubola ngesantya esikhawulezayo phantsi kweemeko ezithile. Umzekelo, kubukho bobumdaka obuthile obuneasidi kwintsimbi ekrwada okanye kwiindawo zokufuma okuphezulu, i-potassium cyanide inokuba lula kwi-hydrolysis okanye ezinye iintshukumo zokubola, ezinokucutha ukuhlangana kwee-ion ze-cyanide ezifumanekayo kwaye ngaloo ndlela ukusebenza kakuhle kwenkqubo yokutsalwa kwentsimbi exabisekileyo.

4. Iingqwalasela kunye noKhuseleko

Zombini i-sodium cyanide kunye ne-potassium cyanide zizinto eziyityhefu kakhulu. Nangona kunjalo, ngenxa yokusetyenziswa ngokubanzi kwe-sodium cyanide kwishishini, kukho iiprothokholi zokhuseleko ezisekwe kakuhle kunye neenkqubo zokuphatha. Abasebenzi kwizityalo zokulungisa izimbiwa baqeqeshelwa ukuphatha i-sodium cyanide ngokukhuselekileyo, kwaye izixhobo ezisetyenziselwa ukugcina, ukuthutha, kunye nokusetyenziswa kwe-sodium cyanide yenzelwe ukhuseleko engqondweni.

Ishishini liye laqulunqa imilinganiselo yokhuseleko olubanzi lwe-sodium cyanide, njengeenkqubo ezifanelekileyo zokungenisa umoya kwiindawo zokucubungula, iimfuno zezixhobo zokukhusela zomntu, kunye nezicwangciso zokuphendula ngokukhawuleza xa kukho ukuchithwa okanye ukuvuza. Ukutshintshela kwi-potassium cyanide kuya kufuna ukuphinda kuqeqeshwe abasebenzi kunye nohlengahlengiso olunokubakho lweziseko ezingundoqo zokhuseleko kumzi-mveliso, nto leyo eyongeza umaleko ongeyomfuneko wobunzima kunye neendleko.

Ukuqukumbela, ukhetho lwe-sodium cyanide phezu kwe-potassium cyanide kwi-mineral processing sisigqibo esinengqiqo esekelwe kwizinto zoqoqosho, iikhemikhali kunye nokhuseleko. Ixabiso eliphantsi, ukunyibilika okufanelekileyo kunye nokusebenza kwakhona, ukuzinza okulungileyo, kunye neenkqubo zokhuseleko ezimiselweyo ezinxulumene ne-sodium cyanide zenza kube yinto ekhethiweyo yokukhupha izimbiwa ezixabisekileyo kwi-ores.
