Shaanxi United Chemical: Na-enye Green Sodium Cyanide Solution maka Kazakhstan

N'ọhịa nke ngwaahịa kemịkalụ, Shaanxi United Chemical anọwo na-ebute ụzọ n'ihu ụlọ ọrụ na-eji ihe oyiyi ọkachamara na ọrụ. Ugbu a, a na-asọpụrụ anyị nke ukwuu inwe ike ịnye ihe dị elu sodium cyanide ngwaahịa maka Kazakhstan.

sodium cyanide, dị ka ihe dị mkpa kemịkalụ akụrụngwa, a na-eji n'ọtụtụ ebe n'ọtụtụ ụlọ ọrụ mmepụta ihe, karịsịa na gold Ngwuputa na uru ụlọ ọrụ. Agbanyeghị, n'ihi akụrụngwa pụrụ iche ya, gọọmentị China na-achịkwa ya nke ọma. Anyị makwaara nke ukwuu nke nwere ike imerụ ahụ sodium cyanide na gburugburu ebe obibi. Ọ bụrụ na a naghị emeso cyanide - nwere mmiri mkpofu a na-emepụta na nhazi ọla edo na usoro irite uru, ọ ga-abụ nnukwu ihe egwu gburugburu ebe obibi. A na-ekpebi cyanide na mmiri mkpofu nke osisi cyanidation ọla edo site na nhazi nke ore na ọnọdụ ọrụ. Na mgbakwunye na cyanide, o nwekwara ihe ndị dị ka thiocyanate. Ọtụtụ n'ime thiocyanates ndị a na-abịa site na usoro ikuku na mmepụta ma ọ bụ mmeghachi omume n'etiti cyanide na atom sọlfọ na-adịghị akwụsi ike n'oge leaching. Ọzọkwa, cyanide - nwere mmiri mkpofu nwere nnukwu nnukwu ụlọ cyanide metal na-egbu egbu na cyanides. Ya mere, Shaanxi United Chemical abụghị naanị onye na-eweta ngwaahịa kamakwa onye na-eme ya Environmental Protection.

Uru nchekwa gburugburu ebe obibi

Maka nchekwa gburugburu ebe obibi, anyị nwere nnukwu uru. Ụlọ ọrụ a na-etinye nnukwu ego na nyocha na mmepe teknụzụ, ma na-enye nkwado teknụzụ zuru oke maka nsogbu gburugburu ebe obibi nwere ike ịpụta n'oge mmepụta, njem, nchekwa na ojiji nke Sodium cyanide . Ndị otu ọkachamara anyị nwere ike inyere ụlọ ọrụ mpaghara dị na Kazakhstan aka ịmepụta usoro njikwa gburugburu ebe obibi zuru oke ma belata mmepụta ihe na-emerụ emerụ site na isi iyi. Dịka ọmụmaatụ, n'usoro mmepụta, anyị na-anabata teknụzụ mmepụta akwụkwọ ndụ akwụkwọ ndụ dị elu iji melite ojiji ihe eji emepụta ihe ma belata ikuku mkpofu.

Ụzọ ọgwụgwọ maka Cyanide - mmiri mkpofu nwere

Na ọgwụgwọ nke cyanide - nwere mmiri mkpofu na ụlọ ọrụ na-egwupụta ọla edo na ụlọ ọrụ na-erite uru, anyị na-amụta ụzọ dị iche iche tozuru okè ma dị irè:

• Usoro Nhicha Alkaline Chlorine : Nke a bụ ụzọ a na-ejikarị ebibi Cyanide n'ime mmiri mkpofu nke osisi cyanidation ọlaedo, a na-ejikwa ya nke ọma n'ịgwọ mmiri mkpofu nke osisi cyanide electroplating, osisi cyanidation gold mine, osisi cyanidation gold na ngwaọrụ ndị ọzọ. Ụkpụrụ ya bụ iji mmiri chlorine, gas chlorine ma ọ bụ ntụ ntụ ọcha mee ka cyanide dị n'ime mmiri mkpofu ghara ịdị irè dịka carbon dioxide na nitrogen.

• Sulfur Dioxide - Usoro Oxidation Ikuku : A makwaara ya dịka usoro InCo, ụlọ ọrụ American InCo Metals mepụtara ya na mbido afọ 1980. Usoro a na-eji sulfur dioxide na ikuku dị ka oxidants iji mee ka cyanides dị n'ime mmiri mkpofu dị n'okpuru ọnọdụ nke copper-ion catalyst, na-emepụta bicarbonate na ammonium ferrous sulfate. Ọ bụghị naanị na ọ nwere ike iwepụ ion cyanide efu, hydrogen molecular na cyanides dị mgbagwoju anya, kamakwa ọ na-ewepụ mgbagwoju ferrocyanide ndị siri ike iwepụ site na usoro chlorination, na-eme ka mmiri mkpofu a gwọrọ ruru ụkpụrụ mwepụta.

• Usoro Oxidation Hydrogen Peroxide : Ọ dị mma maka ịgwọ obere mmiri mkpofu nke nwere cyanide. N'okpuru ọrụ nke copper-ion catalyst na alkaline pH nke 10-11, hydrogen peroxide na-eme ka cyanide dị ọcha iji mepụta ihe kemịkalụ dị ka oxides na ammonium ferrous sulfate. N'ime ha, ion metal dị arọ na-emepụta hydroxide precipitates, ferrocyanide ions na ion metal dị arọ ndị ọzọ na-etolite nnu ferrocyanide dị mgbagwoju anya.

• Usoro Oxidation Ozone : Ọ dị mma maka ịgwọ mmiri mkpofu dị nro - nke nwere cyanide. Na uru pH alkaline nke 11-12. ozone na-eme ka cyanide dị ọcha iji mepụta bicarbonate na nitrogen. Ọ bụ ezie na usoro a enweghị ike iwepụ mgbagwoju anya ferrocyanide, ọ nwere uru nke ịdị mfe na ịdị mfe. Ọ dịghị mkpa ịzụta na ibuga kemịkalụ, naanị ihe na-emepụta ozone ka achọrọ iji gwọọ cyanide - nke nwere mmiri mkpofu. Agbanyeghị, ọ nwekwara ọghọm nke oriri ike dị elu na ọnụ ahịa ọgwụgwọ dị elu. Iji dozie nsogbu nke mgbagwoju anya ferrocyanide, Tinker Air Force Base na United States mepụtara usoro jikọtara ọnụ nke photolysis ultraviolet na usoro ozone ma nwalee ya nke ọma. Mgbe e mesịrị, e mekwara usoro O3/photolysis yiri ya.

Ụgbọ njem na nkwa nchekwa

Na njikọ njem, anyị nwere akụrụngwa njem kemịkalụ dị ize ndụ ọkachamara na usoro nlekọta njem siri ike iji hụ na sodium cyanide rutere ebe a na-aga n'enweghị nsogbu ma na-ebelata mmetụta na gburugburu ebe obibi n'ụzọ. N'ihe gbasara nchekwa, anyị na-enye ngwọta nchekwa sayensị na akụrụngwa iji gbochie ihe mberede dị ka ntapu site na imetọ ala na mmiri mmiri. N'ọnọdụ ndị a na-atụghị anya ya, anyị nwekwara teknụzụ ọgwụgwọ mberede ọkachamara na ndị otu nwere ike ịzaghachi ngwa ngwa ma belata mmebi gburugburu ebe obibi.

Shaanxi United Chemical agba mbọ ka ya na ndị mmekọ na Kazakhstan na-arụkọ ọrụ iji nweta mmepe akwụkwọ ndụ akwụkwọ ndụ ma na-adigide ma na-enye ngwaahịa sodium cyanide dị elu. Anyị kwenyere na site na mbọ anyị, anyị nwere ike itinye aka na mmepe mmepụta ihe nke Kazakhstan ma tinyekwa nkwa maka nchekwa gburugburu ebe obibi.
