Shaanxi United Chemical: Ukubonelela ngezisombululo zeSodium Cyanide eziluhlaza zeKazakhstan

Kwintsimi yokubonelela ngemveliso yeekhemikhali, uShaanxi United Chemical ibisoloko iphambili kwishishini elinomfanekiso oqeqeshiweyo nonoxanduva. Ngoku, sinelunda kakhulu ukuba sikwazi ukubonelela ngomgangatho ophezulu Isodium cyanide iimveliso zaseKazakhstan.

Sodium i-cyanide, njengesixhobo esibalulekileyo sekhemikhali ekrwada, sisetyenziswa kakhulu kwiindawo ezininzi zoshishino, ngakumbi kwimigodi yegolide kunye neshishini lokuxhamla. Nangona kunjalo, ngenxa yeempawu zayo ezikhethekileyo, ilawulwa ngokungqongqo ngurhulumente waseTshayina. Sikwanolwazi olunzulu ngokwenzakala okunokubakho kwe sodium cyanide kokusingqongileyo. Ukuba i-cyanide - equlathe amanzi amdaka aveliswa kumbiwa wegolide kunye nenkqubo yokuzuza uncedo ayiphathwa kakuhle, iya kuba yingozi enkulu kwindalo esingqongileyo. I-cyanide kumanzi amdaka ezityalo zegolide ze-cyanidation zichongwa ngokubunjwa kwe-ore kunye neemeko zokusebenza. Ukongeza kwi-cyanide, ikwaqulethe izinto zekhemikhali ezifana ne-thiocyanate. Uninzi lwezi thiocyanates zivela kwinkqubo ye-aeration kwimveliso okanye ukusabela phakathi kwe-cyanide kunye ne-athomu yesulfure engazinzanga ngexesha lokuhlamba. Ngaphezu koko, i-cyanide-equlethe amanzi amdaka iqulethe isixa esikhulu se-cyanide yensimbi enetyhefu kakhulu kwaye iicyanides. Ngoko ke, Shaanxi United Chemical ayingomthengisi wemveliso kuphela kodwa ikwayingcali ye Ukukhuselwa kwendalo.

Izinto eziluncedo zokuKhuselwa kokusiNgqongileyo

Ngokuphathelele ukhuseleko lokusingqongileyo, sineenzuzo ezibalulekileyo. Le nkampani ityale imali eninzi kuphando nophuhliso lwetekhnoloji, kwaye inika inkxaso epheleleyo yobugcisa kwiingxaki zokusingqongileyo ezinokuvela ngexesha lokuveliswa, ukuthuthwa, ukugcinwa kunye nokusetyenziswa kweSodium cyanide . Iqela lethu leengcali linokunceda amashishini asekuhlaleni eKazakhstan ukuba aseke inkqubo epheleleyo yolawulo lokusingqongileyo kwaye anciphise ukuveliswa kongcoliseko oluvela kumthombo. Umzekelo, kwinkqubo yemveliso, sisebenzisa ubuchwepheshe obuphambili bokwenziwa koluhlaza ukuphucula ukusetyenziswa kwezinto eziluhlaza kunye nokunciphisa ukukhutshwa kwenkunkuma.

Iindlela zoNyango lweCyanide - equlathe Amanzi amdaka

Kunyango lwe-cyanide-equlathe amanzi amdaka kwimigodi yegolide kunye neshishini lokuxhamla, sinobuchule obuhlukeneyo beendlela ezivuthiweyo nezisebenzayo:

• Indlela ye-Alkaline Chlorination : Le yindlela eqhelekileyo yokutshabalalisa i-Cyanides emanzini amdaka ezityalo ze-gold cyanidation kwaye isetyenziswa kakhulu kunyango lwamanzi amdaka lwezityalo ze-cyanide electroplating, izityalo ze-gold mine cyanidation, izityalo ze-gold cyanidation kunye nezinye iiyunithi. Umgaqo wayo kukusebenzisa i-chlorine engamanzi, igesi ye-chlorine okanye i-bleaching powder ukuze i-oxidize i-cyanide emanzini amdaka ibe zizinto ezingenabungozi ezifana ne-carbon dioxide kunye ne-nitrogen.

• Indlela yeSulfur Dioxide - Air Oxidation : Eyaziwa ngokuba yindlela ye-InCo, yaphuhliswa yi-American InCo Metals Company ekuqaleni kweminyaka yoo-1980. Le ndlela isebenzisa i-sulfur dioxide kunye nomoya njenge-oxidants ukuze i-oxidize i-cyanides emanzini amdaka phantsi kwemeko ye-copper-ion catalyst, ivelise i-bicarbonate kunye ne-ammonium ferrous sulfate. Ayinakususa kuphela ii-ion ze-cyanide zasimahla, i-hydrogen ye-molecular kunye ne-cyanides ezintsonkothileyo, kodwa ikwasusa nee-complexes ze-ferrocyanide ezinzima ukuzisusa ngendlela ye-chlorination, okwenza amanzi amdaka aphathweyo ahlangabezane nemigangatho yokukhupha.

• Indlela yokuOxidation yeHydrogen Peroxide : Ifanelekile ukunyanga amanzi amdaka ane-cyanide ephantsi. Phantsi kwesenzo se-catalyst ye-copper-ion kwixabiso le-alkaline pH le-10 - 11, i-hydrogen peroxide ioxidation kwi-cyanides ukuze ivelise izinto zeekhemikhali ezifana ne-oxides kunye ne-ammonium ferrous sulfate. Phakathi kwazo, ii-ion ze-heavy metal zenza i-hydroxide precipitates, kwaye ii-ion ze-ferrocyanide kunye nezinye ii-ion ze-heavy metal zenza i-ferrocyanide complex salts.

• Indlela yokuOxidation ye-Ozone : Ifanelekile ukunyanga i-cyanide enyibilikisiweyo - equlethe ulwelo olungcolileyo. Kwixabiso le-pH ye-alkaline eliyi-11 - 12, i-ozone i-oxidize i-cyanides ukuze ivelise i-bicarbonate kunye ne-nitrogen. Nangona le ndlela ingenakususa ii-ferrocyanide complexes, ineengenelo zokulula nokulula. Akukho mfuneko yokuthenga nokuthutha iikhemikhali, kwaye kufuneka i-ozone generator kuphela ukunyanga amanzi amdaka aqulethe i-cyanide. Nangona kunjalo, ikwanazo neengxaki zokusetyenziswa kwamandla aphezulu kunye neendleko zonyango eziphezulu. Ukusombulula ingxaki yee-ferrocyanide complexes, iTinker Air Force Base eMelika yaphuhlisa inkqubo edibeneyo ye-ultraviolet photolysis kunye nendlela ye-ozone kwaye yavavanya ngempumelelo. Kamva, kwaphuhliswa nendlela efanayo ye-O3/photolysis.

Ingqinisekiso yezoThutho kunye noGcino

Kwikhonkco lezothutho, sixhotyiswe ngezixhobo zothutho zeekhemikhali ezinobungozi kunye neenkqubo ezingqongqo zolawulo lwezothutho ukuqinisekisa ukuba i-sodium cyanide ifika kwindawo ekuyiwa kuyo ngokukhuselekileyo ngelixa inciphisa impembelelo yokusingqongileyo endleleni. Ngokubhekiselele kugcino, sibonelela ngezisombululo zogcino lwenzululwazi kunye nezibonelelo zokuthintela iingozi ezinjengokuvuza ekungcoliseni umhlaba kunye nemithombo yamanzi. Kwimeko yeemeko ezingalindelekanga, sikwanabo ubuchwepheshe bonyango olungxamisekileyo kunye namaqela anokuthi aphendule ngokukhawuleza kwaye anciphise umonakalo wokusingqongileyo.

Shaanxi United Chemical uzibophelele ekusebenzeni ngesandla kunye namaqabane eKazakhstan ukuphumeza uphuhliso oluluhlaza kunye noluzinzileyo ngelixa ubonelela ngemveliso ephezulu yesodium cyanide. Sikholelwa ukuba ngeenzame zethu, sinokuba negalelo kuphuhliso lweshishini laseKazakhstan kwaye songeze isiqinisekiso sokhuseleko lwendawo yendawo.
