Kuvandudza Goridhe Kudzoreredza Matengo kuburikidza neKusanganiswa Kushandiswa kweSodium Cyanide uye Potassium Bromide.

ziviso

Muindasitiri yekuchera nekubvisa goridhe, kuwedzera huwandu hwegoridhe rinodzoserwa kubva mumatombo anokosha zvikuru. Imwe nzira yakaratidza kuti inoshanda ndeyekushandisa pamwe chete Sodium cyanide nePotassium bromide . Chinyorwa ichi cheblog chichaongorora mashandiro anoita musanganiswa uyu uye mabhenefiti awo mukuvandudza kudzoserwa kwegoridhe.

Basa reSodium Cyanide muKuchera Goridhe

Sodium cyanide yagara iri chinhu chakakosha mukubvisa goridhe . Nzira yecyanidation, iyo yakatanga muna 1887 payakatanga kushandiswa kubvisa goridhe nesirivha, ichiri nzira huru muindasitiri yegoridhe yepasi rose. Maitiro acho ari nyore. Kune goridhe remhando yepasi, dombo rinotanga rapwanywa kusvika pahukuru hwakakodzera kuti riwedzere nzvimbo yaro yepamusoro, zvichiita kuti reaction iite nyore necyanide solution. Zvadaro, cyanide solution (inowanzo nyungudutswa mumvura) inounzwa. Kana paine oxygen, goridhe riri mudombo rinoita reaction nemaion ecyanide kuti rigadzire soluble gold cyanide complexes. Maitiro emakemikari akareruka ndeaya: 4Au + 8NaCN + O₂ + 2H₂O → 4Na(Au(CN)₂) + 4NaOH. Izvi zvinobvumira goridhe kuti rinyungudutswe uye riparadzaniswe neore matrix. Sodium cyanide ine hukama hwakakura negoridhe, zvichiita kuti ikwanise kunyungudutsa goridhe kubva mudombo, kunyangwe kana goridhe rakawanda rakaderera. Kusarudza uku kwakakosha sezvo kuchibvumira kuburitswa kwegoridhe kubva mumatombo ane zvimwe zvicherwa zvakawanda. Kazhinji, zvichienderana nerudzi rwematombo aya, cyanidation ne sodium cyanide inogona kuwana mwero wepamusoro wekudzoserwa kwegoridhe, kazhinji kubva pa50 - 80%, uye mune dzimwe nguva, kusvika pa90%.

Basa rePotassium Bromide

Potassium bromide inoitawo basa rakakosha mukutorwa kwegoridhe. Bromide - yakavakirwa goridhe kutorwa inzira inovimbisa iyo yakadzidzwa zvakanyanya. Kushandisa bromide sechinhu chinotsiva kana kuti chinonatsiridza mukutora goridhe kune zvakati wandei zvakanakira. Yakachipa zvakachipa, ine mwero wakakwira wekubuda (kubvira pa90 - 95% mune dzimwe nguva), kukurumidza kubuda kwemvura, haina-kuora panzvimbo dzakakodzera, uye inogona kunge isiri-chepfu pane yakaderera. Kana ichishandiswa pamwe chete nemamwe mareagents, inogona kuwedzera kushanda kwese kweiyo goridhe kudhirowa maitiro.

Iyo Synergy yeSodium Cyanide uye Potassium Bromide

Kana sodium cyanide uye potassium bromide zvichishandiswa tandem, vanogona kugadzira synergistic mhedzisiro. Iyo bromide ion kubva potassium bromide inogona kudyidzana negoridhe - cyanide complexes inoumbwa ne sodium cyanide. Kudyidzana uku kunogona kutungamirira pakuumbwa kwezvimwe zvakagadzikana kana zvakanyanya soluble complexes, izvo zvinogona kuwedzera kunyunguduka kwegoridhe mune mhinduro. Semuyenzaniso, maion ebromide anogona kutora chikamu mukuita kunogadzirisa chimiro chegoridhe - cyanide complex, zvichiita kuti zvive nyore kuti goridhe riwedzere kugadziriswa nekuparadzaniswa kubva kune mhinduro. Pamusoro pezvo, kuvepo kwebromide kunogona kukanganisawo zvimiro zvepasi pezvimedu zvegoridhe muore. Zvinogona kubatsira kupaza chero machira epamusoro kana tsvina pazvidimbu zvegoridhe, zvichibvumira cyanide ions kubva pasodium cyanide kuti iwane mukana wepamusoro pegoridhe, zvichisimudzira kunyungudika kwegoridhe.

Zvidzidzo uye Migumisiro

Zvidzidzo zvakawanda uye mashandisirwo anoshanda zvakaratidza kushanda kwemubatanidzwa uyu. Mune mamwe maseti ekuyedza, pakurapa ores yegoridhe neyakasanganiswa mhinduro yesodium cyanide uye potassium bromide, iyo goridhe yekudzoreredza mitengo yaive yakakwira zvakanyanya kana ichienzaniswa nekushandisa sodium cyanide chete. Semuenzaniso, mune imwe ongororo, mwero wekudzoreredza goridhe wakawedzera kubva pa70% pakushandisa chete sodium cyanide kusvika pamusoro pe85% apo potassium bromide yakawedzerwa kuhurongwa. Mumabasa ezvicherwa zvepasi rose, mimwe migodhi yakatora kushandiswa kwakabatanidzwa kweaya marejenti maviri yakashuma kuvandudzwa 经济效益. Vakakwanisa kutora goridhe rakawanda kubva pachiyero chakafanana chesimbi, izvo zvisingangokwidzi kukosha kwechishandiso asiwo zvinowedzera purofiti yekushanda kwemigodhi.

Mafungiro Ezvakatipoteredza uye Kuchengetedzwa

Zvakakosha kuziva kuti zvose sodium cyanide uye potasium bromide zvinoda kubatwa nekungwarira. Sodium cyanide chinhu chine muchetura zvakanyanya, uye kushandiswa kwayo uye kutakura kunoenderana nemirairo yakaoma. Chero zvigadziriso zvemarara zvine sodium cyanide zvinofanirwa kubatwa nemazvo kudzivirira kusvibiswa kwezvakatipoteredza. Hydrogen peroxide kurapwa, semuenzaniso, inogona kushandiswa kuita oxidize uye kuderedza sodium cyanide mumarara ezvinwiwa, kugadzira sodium bicarbonate uye ammonia gasi. Potassium bromide, nepo kazhinji isina muchetura kupfuura sodium cyanide, inodawo kubatwa kwakakodzera kuti ive nechokwadi chekuchengetedzwa munzvimbo yebasa. Paunenge uchishandisa musanganiswa weaya mareagents maviri, makambani emigodhi anofanirwa kuita akasimba ekuchengetedza maprotocol uye maitiro ekutonga kwezvakatipoteredza kuti aderedze njodzi.

mhedziso

Iko kushandiswa kwakasanganiswa kwesodium cyanide uye potasium bromide kunopa nzira inovimbisa yekusimudzira mitengo yekudzoreredza goridhe. Nekunzwisisa kupindirana kwemakemikari pakati peaya mareagents maviri uye mabasa avo ega ega mukuita kwekuchera goridhe, makambani emigodhi anogona kukwidziridza nzira dzawo dzekuchera. Nekudaro, zvakakosha kuenzanisa mabhenefiti angangove nematanho akasimba ezvakatipoteredza uye ekuchengetedza. Sezvo kudiwa kwegoridhe kuri kuramba kuchikura uye nepamusoro - giredhi regoridhe dhipoziti richiva shoma, hunyanzvi hwekuita semusanganiswa uyu huchaita basa rakakosha mukusimudzira indasitiri yezvicherwa zvegoridhe.
