Nei China Yave Mugadziri Anotungamira Pasirose Mugadziri weSodium Cyanide

Munguva kubva 2008 kusvika 2015. China yakaita shanduko inoshamisa munzvimbo ye Sodium Cyanide production. Yakachinja kubva pakuva mutengi wekemikari ine muchetura zvikuru iyi kusvika pakuva mugadziri mukuru wepasi rose, muchengeti, uye mutengesi. Iyi shanduko yakakosha inobvunza mubvunzo: sei China yakabuda senyika inotungamira mu sodium cyanide kugadzirwa?

Global Sodium Cyanide Production Landscape

Japan yaive pakati pevakatanga kupinda Sodium cyanide production domain. Pasinei nekutonga kweUnited States (ine makambani akaita seDuPont anoverengera 43% yehuwandu hwekugadzira kugadzirwa kwepasi rose) uye Western Europe mune yepasi rose sodium. cyanide chiitiko chekugadzira, makambani eJapan akadai saKuraray neNippon Soda, pakati pevamwe, akagonesa Japan kuchengetedza nzvimbo yekukwikwidza. Muna 1999. chikamu che50% chesodium cyanide yakabuda muJapan yakaiswa mukugadzirwa kwemethionine, iyo inonyanya kushandiswa mukugadzira chikafu chemhuka.

Zvisinei, pasi rose, kushandiswa kwekutanga kwe sodium cyanide kuri mukutorwa kwegoridhe. Sezvo tekinoroji yekushandisa sodium cyanide mukuchera goridhe yakatanga muma1980s, yakagamuchirwa zvakanyanya mumaindasitiri egoridhe munyika dzakasiyana. Somuenzaniso, muSouth Africa, 99.5% yekucherwa kwegoridhe inovimba nenzira iyi; muUnited States, nhamba inomira pa88.1%, uye muAustralia, i84.9%. Parizvino, inoshamisa 75% yepasi rose sodium cyanide inopedzwa nechikamu chemigodhi. Maindasitiri ezvicherwa zvegoridhe kuNorth America, South America, Russia, Central Asia, Australia, South Africa, neChina ndiwo ari kunyanya kutenga kemikari iyi.

Kukwira kwemitengo yegoridhe kwave nekukanganisa kwakananga pamutengo we sodium cyanide inoshandiswa mukuchera goridhe. Mukutanga kwe2000s, mutengo wepasi rose we sodium cyanide wakanga wakapoteredza \ (1.600 patani, iyo yakawedzera kusvika \) 2.800 patani. Uku kukwira kwemitengo kwakakurudzira kuwedzera kwekugadzirwa kwesodium cyanide pasi rose. Russia nePeru, semuenzaniso, zvakavaka zvimiro zvekugadzira sodium cyanide zvine simba repagore re40.000 matani esodium cyanide yakasimba. Asi munguva pfupi, vakaputirwa nekukura kweChina munzvimbo iyi.

China's Sodium Cyanide Production Rwendo

Kupinda kweChina mukugadzirwa kwesodium cyanide kwakatanga muma1960, Shanghai ichive nzvimbo yekutanga kugadzira. Pakazosvika ma1980s, indasitiri yepetrochemical iri kuwedzera yakakonzera kuwedzera kwakanyanya kwekuda kwe sodium cyanide. Pamberi pe 2008. China yaivimba nekutengesa kunze kwenyika, ichiunza 10.000 - 30.000 matani e sodium cyanide gore negore.

Nekudaro, masimba maviri ekukura kudiwa kwemumba neyekunze, pamwe nekukwira kwemitengo, kunyanya nekuda kwekuwedzera kwezvinodiwa Gold Mining Indasitiri, yakafambisa kugadzirwa kwe sodium cyanide yekuChina. Pakazosvika 2009. China yakakwanisa kubudirira kuburikidza nekuva mutengesi kunze kwenyika sodium cyanide.

Muna 2011. Kugadzirwa kwepagore kweChina sodium cyanide kwakaswedera pedyo ne400.000 matani. Parizvino, China ine zita remugadziri mukuru pasi rose we sodium cyanide. Pamusoro pekuzadzisa zvinodiwa mudzimba, inotumira kunze kwenyika anopfuura 70.000 matani gore rega rega. Munguva yekuwedzera nekukurumidza kweiyo sodium cyanide indasitiri, mapurovhinzi akaita seAnhui neHebei akabuda senzvimbo huru dzekugadzira.

Kutyaira Mauto Kuseri kweKukwira kweChina

Gold Mining Indasitiri

China haingori mugadziri anotungamira asiwo mutengi mukuru wegoridhe. Kuenderera mberi kwekukura kwekugadzirwa kwegoridhe uye kushandiswa kwakonzera kuwedzera kukuru kwekuda kwe sodium cyanide mukucherwa kwegoridhe. Kubuda kwegoridhe rekuChina kwakagara kuri pakati pepamusoro-soro pasi rose. Kushandiswa kwakawanda kweiyo cyanide - yakavakirwa goridhe nzira yekubvisa, iyo inoshanda zvakanyanya mukubvisa goridhe kubva muore, yakabatsira zvakanyanya mukudiwa kukuru kwesodium cyanide. Sezvo indasitiri yemigodhi yegoridhe iri kuramba ichikura, zvese maererano nemapurojekiti matsva emigodhi uye nekuwedzera kwearipo, kudiwa kwesodium cyanide sechinhu kiyi yekubvisa reagent kwakura zvakaenzana.

Mutengo - kushanda nesimba uye Scale Advantage

Vagadziri veChinese vakaisa mari pahupfumi hwehukuru. Nekugadzirwa kwakakura, vakakwanisa kuderedza mari yekugadzira zvakanyanya. Mutengo uyu - kushanda nesimba kwakaita kuti Chinese - igadzire sodium cyanide iwedzere kukwikwidza mumusika wepasirese. Zvakare, kuvandudzwa kwehunyanzvi hwekugadzira matekinoroji muChina kwakawedzera mashandiro ekugadzira uye kunaka kwechigadzirwa. Iko kugona kugadzira yakakwira-yemhando sodium cyanide nemutengo wakaderera kwakakwezva vatengi vekumba nevekunze, nekudaro vachifambisa kukura kweindasitiri.

Downstream Indasitiri Development

Sodium cyanide inoshanda sechinhu chakakosha mbishi mumaindasitiri akasiyana epasi, kusanganisira kugadzirwa kwemakemikari epakati, mishonga, mishonga yezvipembenene, uye electroplating. Kukura kwemaindasitiri aya muChina kwakagadzira kudiwa kwakasimba kwesodium cyanide. Semuenzaniso, muindasitiri yemishonga, sodium cyanide inoshandiswa mukubatanidza mamwe epakati emishonga. Sezvo indasitiri yemishonga yeChinese ichiwedzera uye ichiwedzera kukwikwidza pasi rose, kudiwa kwesodium cyanide sechinhu chakakosha chekushandisa kwakawedzerawo. Saizvozvo, muindasitiri ye electroplating, iyo inoshandiswa zvakanyanya mukugadzira zvigadzirwa zvemagetsi uye zvekushongedza, sodium cyanide inobata basa rakakosha pakuita kuti yakakwira - yemhando yeplating. Kukura kweaya maindasitiri epasi kwakapa hwaro hwakasimba hwekuvandudza kweChina sodium cyanide kugadzirwa.

mhedziso

Muchidimbu, shanduko yeChina kuita inotungamira pasi rose kugadzira sodium cyanide mhedzisiro yemusanganiswa wezvinhu. Kuwedzera kuri kuda kubva kuindasitiri yemigodhi yegoridhe, mutengo - nzira dzekugadzira dzinoshanda, uye kusimukira kwemaindasitiri epasi zvakakonzera kukura kunoshamisa uku. Nekudaro, nekukura uku kunouya basa rekuona kuchengetedzwa kwakasimba uye matanho ekuchengetedza kwezvakatipoteredza. Tichifunga nezve muchetura wesodium cyanide, kubata kwakaringana, kuchengetedza, uye kutakura kwakakosha zvakanyanya. Sezvo China ichiramba iri pamberi pekugadzirwa kwesodium cyanide, inofanirwawo kutungamira mukuita maitiro akanakisa mukuchengetedza uye kutonga kwezvakatipoteredza kudzikisa njodzi dzinogona kuitika dzine chekuita nekemikari ine njodzi iyi.
