Sei sodium cyanide yakasarudzwa panzvimbo ye potassium cyanide mumamineral processing?

1. Mutengo - Chinhu Chekutanga

Chimwe chezvikonzero zvakakosha zvekusarudza Sodium cyanide (NaCN) pamusoro Potassium cyanide (KCN) mutengo. Sodium yakanyanya kuwanda muEarth crust kana ichienzaniswa nepotassium. Kugadzirwa kwe Sodium Cyanide zvinosanganisira zvinhu zvinodhura zvisingadhuri uye nzira dzekugadzira dziri nyore.

Potassium makomisheni anowanzo anoda kudhirowa kwakaoma uye matanho ekuchenesa. Kune yakakura - chiyero Mineral processing maoparesheni, ayo anodya huwandu hwakawanda hwe cyanide, musiyano wemari pakati sodium cyanide uye potassium cyanide inogona kushandura mukuchengetedza kwakakosha. Semuyenzaniso, kana mugodhi wegoridhe ukagadzira zviuru zvematani e ore zuva nezuva, kushandisa sodium cyanide pachinzvimbo che potassium cyanide kunogona kuchengetedza mamirioni emadhora pagore mumutengo we reagent.

2. Solubility uye Reactivity

Solubility

Sodium cyanide ine yakanakisa solubility mumvura. Mumamiriro ezvinhu ekugadzirisa zvicherwa, musanganiswa wecyanide wakanyungudika wakakosha sezvo uchibvumira kuumbwa kwakanaka kwecyanide - simbi yakaoma inodiwa pakunyungudutsa simbi dzinokosha. Pamamiriro ezvinhu akajairwa, sodium cyanide inonyungudika mumvura, ichiva nechokwadi chekuti cyanide ions (CN⁻) inowanikwa muhuwandu hwakakwana kuita negoridhe kana sirivheri mune ore.

Potassium cyanide inonyungudika mumvura, asi kunyungudika kwesodium cyanide kunopfuura kukwana kune mazhinji mamineral processing application. Hapana zvakakosha pakushandisa potassium cyanide maererano nekunyunguduka, uye mari yakawedzerwa inobatanidzwa nayo haikodzeri kushandiswa kwayo apo sodium cyanide inogona kuwana chiyero chakafanana chekubudirira mukugadzira mishonga inodiwa yemvura.

Reactivity

Mukunyungudusa goridhe nesirivheri pamberi peokisijeni, ese ari maviri sodium cyanide uye potassium cyanide anotevera yakafanana kemikari reaction mechanism. Iyo cyanide ions inobata nesimbi mu electrochemical process, ichiita soluble metal - cyanide complexes. Nekudaro, iyo reactivity ye sodium cyanide yakanyatso dzidza uye yakagadziridzwa mumaindasitiri ezvirongwa.

The reaction rate of sodium cyanide ine goridhe nesirivha pasi peyakajairika mineral processing conditions (pH kutenderera 9 - 11. kuvapo kweokisijeni yakanyungudika) yakatsvakurudzwa zvakanyanya, uye maitiro ekugadzirisa akave akanaka - akagadziridzwa kwemakumi emakore. Kujairira uku kunobvumira kunyatso kudzora kwekuita leaching, kuve nechokwadi chekuburitsa kwakakwira goho resimbi dzakakosha. Kuchinjira ku potassium cyanide kunoda kuwongororazve uye nekugona kugadziridzazve aya maitiro, inova inodhura uye inopedza nguva kuedza.

3. Kuramba

Sodium cyanide inoratidza kugadzikana kwakanaka kwemakemikari pasi pemamiriro anowanzo sangana mumamineral processing mashandiro. Haiori nyore kana paine mhepo, unyoro, kana tsvina yakajairika inowanikwa mumatombo. Uku kugadzikana kwakakosha sezvo ichivimbisa kuti cyanide mhinduro inochengetedza kushanda kwayo nekufamba kwenguva.

Potassium cyanide, kune rumwe rutivi, inogona kuita zvishoma zvishoma mune dzimwe nzvimbo uye inogona kuora nekukasira pasi pemamwe mamiriro. Semuyenzaniso, pamberi pehumwe husina kuchena hune acidic muore kana munzvimbo dzine mwando wakanyanya, potassium cyanide inogona kunge iri nyore kuita hydrolysis kana kumwe kuparara, izvo zvinoderedza kuwanda kweiyo cyanide ion uye nekudaro kushanda kweiyo yakakosha simbi yekubvisa.

4. Kubata uye Kuchengetedza Kufunga

Zvose sodium cyanide uye potassium cyanide zvinhu zvine chepfu zvikuru. Nekudaro, nekuda kwekushandiswa kwakapararira kwesodium cyanide muindasitiri, kune yakanyatso kusimbiswa kuchengetedza mapuroteni uye maitiro ekubata. Vashandi muzvicherwa zvekugadzira zvicherwa vanodzidziswa kubata sodium cyanide zvakachengeteka, uye midziyo inoshandiswa kuchengetedza, kutakura, uye kushandiswa kwesodium cyanide yakagadzirwa nekuchengetedzeka mupfungwa.

Indasitiri iyi yakagadzira matanho ekuchengetedza akazara e sodium cyanide, senge masystem ekufemesa mhepo munzvimbo dzekugadzirisa, zvinodiwa zvekuzvidzivirira nazvo, uye zvirongwa zvekupindura zvekukurumidzira kana pakaparara kana kubuda. Kuchinjira ku potassium cyanide kunoda kudzidzisazve vashandi uye zvingango gadzirisa zvivakwa zvekuchengetedza muchirimwa, izvo zvinowedzera husina basa hwekuoma uye mutengo.

Mukupedzisa, kusarudzwa kwe sodium cyanide pamusoro pe potassium cyanide mukugadzirwa kwemaminerari isarudzo ine musoro yakavakirwa pahupfumi, makemikari, uye kuchengetedza zvinhu. Mutengo wakaderera, kunyungudika kwakakodzera uye kuitazve, kugadzikana kwakanaka, uye kudzika nzira dzekuchengetedza dzine chekuita nesodium cyanide inoita iyo sarudzo inosarudzika yekubvisa simbi dzinokosha kubva mu ores.
