Sodium Cyanide

1.  Kev Taw Qhia General ntawm Sodium Cyanide

Sodium Cyanide saum toj no 98 feem pua ​​​​cov khoom dawb crystalline briquette daim ntawv yog tsuas yog siv los ua leaching tus neeg sawv cev hauv cov mining kub nrog cov txheej txheem leaching, nws tseem hu ua Sodium Cyanide, NaCN, CAS#143-33-9, Cymag, Cyanide ntawm sodium, Cyanide ntsev , cyanosodium, Cyanogran, Cyanobrik, Caswell No. 758. thiab lwm yam Anhui Sanji Chemical Co., Ltd. yog tus neeg sawv cev tshwj xeeb ntawm Hebei ChengXin Co., Ltd. hauv cheeb tsam nominated; Hebei ChengXin yog ib lub chaw tsim khoom loj tshaj plaws Sodium Cyanide nyob hauv lub ntiaj teb, txhua xyoo muaj peev xwm tsim tau nyob ib ncig ntawm 120, 000 metrical tons uas muaj nyob ib ncig ntawm 20 feem pua ​​​​ntawm kev ua lag luam thoob ntiaj teb. Hebei ChengXin tseem yog tus kos npe ntawm ICMI (Lub International Cyanide Management Code), uas tau txiav txim siab tias nws cov Sodium Cyanide tswj cov txheej txheem, cov phiaj xwm thiab cov txheej txheem tau tsim thiab tau ua raws li International Cyanide Management Code rau Kev Tsim, Thauj thiab Siv. ntawm Cyanide hauv kev tsim cov kub.

Sodium Cyanide yog cov tshuaj lom neeg siab thiab muab cais raws li Cov Khoom Muag Khoom Txaus Ntshai: 6.1 thiab UN No.: 1689; uas tuaj yeem siv rau khaws cia, ua, tsim thiab kho cov riam phom tshuaj lom neeg; vim li no, nws yog qhov nruj me ntsis saib xyuas & tswj cov khoom raws li United Nation thiab txhua lub tebchaws, EUC (End User Certificate) thiab cov ntaub ntawv ntsig txog yuav tsum tau xa mus rau kev pom zoo ntawm Export License ua ntej xa khoom. Pom tseeb, txhua lub tuam txhab cuam tshuam txog kev tsim khoom thiab thauj khoom ntawm Sodium Cyanide yuav tsum muaj ntawv tso cai thiab tsim nyog suav nrog Chaw Tsim Khoom, Exporter, Logistic, Cia, Carrier, Importer thiab End Users.

Sodium Cyanide ntau lawm tuaj yeem ua nrog cov txheej txheem sib txawv xws li: ammonia sodium txoj kev, cyanide yaj txoj kev, iS-Ib txoj kev, nplaim txoj kev, lub teeb roj tawg txoj kev, vinyl cyanide by-product method. Nyob rau hauv Hebei Chengxin yog siv lub teeb roj tawg txoj kev, lub teeb roj thiab ammonia yog tov nyob rau hauv kev faib ua feem nyob rau hauv txau phom, 280 DEG C ntawm preheating, scission cov tshuaj tiv thaiv nyob rau hauv hluav taws xob arc rauv, thaum 1450 DEG C ntawm kub, cov tshuaj tiv thaiv generates prussic acid gas, los ntawm desusting , txias rau 280 DEG C tom qab, ces nrog absorbing los ntawm cov kua caustic soda tsim sodium cyanide, nrog rau cov tshuaj tiv thaiv mis C6H 14 ntxiv rau 6NH3 → 6HCN ntxiv rau 13H2, HCN ntxiv NaOH → NaCN ntxiv H2O. Lub teeb roj tawg txoj kev tseem yog cov cuab yeej siv dav tshaj plaws rau kev tsim Sodium Cyanide vim kev siv siab coefficient ntawm lub teeb roj thiab kua ammonia, kuj tseem muaj kev nyab xeeb ntau dua kev cog qoob loo hauv micro tsis zoo siab.

2.  Kev siv Sodium Cyanide

Sodium Cyanide tuaj yeem siv rau fumigation, electroplating, extracting kub thiab nyiaj los ntawm ores, thiab tshuaj tsim tshuaj. Txawm li cas los xij, kev rho tawm kub nrog cov txheej txheem leaching yog nws cov ntawv thov tseem ceeb. Txij li thaum Sodium Cyanide yog soluble heev, kub ore tom qab crushing thiab sib tsoo thiab sodium cyanide (NaCN) tov tov yog pub rau hauv loj mechanically stirred tso tsheb hlau luam qhov twg nws yog agitated nrog huab cua raws li ib tug leaching txheej txheem los tsim cov leachate (kub-cyanide complex). Cov huab cua muab cov pa oxygen rau cov txheej txheem kub leaching rau cov khoom siv nruab nrab nplawm lub zog, uas ua rau muaj kev sib cuag zoo dua ntawm cov reactant thiab xyuas kom meej tias cov pulp hauv qab ntawm lub tank tsis tuaj yeem ua ke. Cov khoom noj muaj pes tsawg leeg simulation tuaj yeem yog ore (Au)=0.15 kg/hr, O2=113.45 kg/hr, CN-=2.9117kg/hr, OH- =0 .9519 kg/hr, Na plus=4.0397 kg/hr thiab H2O=55994 kg/hr, as per process flow diagram below:
