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

ziviso

Muindasitiri yemigodhi nekuchera goridhe, kukwidziridza mwero wekudzoreredza goridhe kubva kune ores kwakakosha zvakanyanya. Imwe nzira yakaratidza vimbiso ndeye kushandiswa kwakabatanidzwa kwe Sodium cyanide uye Potassium bromide. Iyi blog post inoongorora kuti musanganiswa uyu unoshanda sei uye nemabhenefiti ayo anogona mukuvandudza kupora kwegoridhe.

Basa reSodium Cyanide muKuchera Goridhe

Sodium cyanide yave kwenguva refu iri kiyi reagent mu Kuchera goridhe process. Nzira yecyanidation, iyo yakatanga muna 1887 payakatanga kushandiswa kuchera goridhe nesirivheri, inoramba iri nzira huru muindasitiri yegoridhe pasi rose. Nzira yacho yakananga. Kune yakaderera-giredhi goridhe ores, ore inotanga kupwanyiwa kusvika pakukura kwakakodzera kuti iwedzere nzvimbo yayo, kufambisa maitiro necyanide solution. Zvadaro, cyanide solution (kazhinji Sodium Cyanide yakanyungudika mumvura) inounzwa. Muhupo hweokisijeni, goridhe muore inopindirana neiyo cyanide ions kuumba goridhe rinonyungudika cyanide complexes. Maitiro emakemikari akareruka ndeaya: 4Au + 8NaCN + O₂ + 2H₂O → 4Na(Au(CN)₂) + 4NaOH. Izvi zvinobvumira goridhe kunyungudutswa uye kuparadzaniswa kubva kune ore matrix. Sodium cyanide ine hukama hwepamusoro kune goridhe, zvichiita kuti ikwanise kunyungudutsa goridhe kubva kune ore, kunyangwe iyo goridhe iri pasi. Kusarudzwa uku kwakakosha sezvo kuchibvumira kutorwa kwegoridhe kubva mumatombo uko mamwe mamineral anogona kunge aripo muhuwandu hwakakura. Muzviitiko zvakawanda, zvichienderana nemhando ye ore, cyanidation ne sodium cyanide inogona kuwana mwero wakakwirira wekudzoreredza goridhe, 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.
