Shaanxi United Chemical: Ho Fana ka Litharollo tsa Green Sodium Cyanide bakeng sa Kazakhstan

Sebakeng sa phepelo ea lihlahisoa tsa lik'hemik'hale, Shaanxi United Chemical esale e le ka pele ho indasteri e nang le setšoantšo sa setsebi le se nang le boikarabelo. Joale, re motlotlo haholo hore ebe re khona ho fana ka boleng bo holimo Sodium cyanide lihlahisoa tsa Kazakhstan.

Sodium cyanide, e le lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse tala, li sebelisoa haholo mafapheng a mangata a indasteri, haholo-holo indastering ea merafo ea khauta le ea melemo. Leha ho le joalo, ka lebaka la thepa ea eona e khethehileng, e laoloa ka thata ke 'muso oa Chaena. Re boetse re tseba ka botebo kotsi e ka bang teng ea sodium cyanide tikolohong. Haeba cyanide - e nang le metsi a litšila a hlahisoang merafong ea khauta le ts'ebetsong ea melemo e sa phekoloe hantle, e tla ba kotsi e kholo ea tikoloho. Cyanide ka metsing a litšila a limela tsa khauta tsa cyanidation e khethoa ke ho hlophisoa ha ore le maemo a ts'ebetso. Ntle le cyanide, e boetse e na le lik'hemik'hale tse kang thiocyanate. Boholo ba li-thiocyanate tsena li tsoa ts'ebetsong ea aeration tlhahiso kapa karabelo lipakeng tsa cyanide le liathomo tse sa tsitsang tsa sebabole nakong ea leaching. Ho feta moo, cyanide - e nang le metsi a litšila e na le lisebelisoa tse ngata tse chefo haholo tsa cyanide. li-cyanides. Ka hona, Shaanxi United Chemical ha se feela mofani oa thepa ea lihlahisoa empa hape ke setsebi sa Tšireletso ea tikoloho.

Melemo ea Tšireletso ea Tikoloho

Mabapi le ts'ireletso ea tikoloho, re na le melemo e mengata. Khampani e tsetela chelete e ngata haholo lipatlisisong tsa theknoloji le nts'etsopele, 'me e fana ka tšehetso e felletseng ea tekheniki bakeng sa mathata a tikoloho a ka hlahang nakong ea tlhahiso, lipalangoang, polokelo le ts'ebeliso ea thepa. Sodium cyanide. Sehlopha sa rona sa litsebi se ka thusa likhoebo tsa lehae Kazakhstan ho theha sistimi e felletseng ea taolo ea tikoloho le ho fokotsa tlhahiso e silafatsang e tsoang mohloling. Ka mohlala, ts'ebetsong ea tlhahiso, re sebelisa mekhoa e tsoetseng pele ea theknoloji e tala ho ntlafatsa tšebeliso ea thepa e tala le ho fokotsa ho ntšoa ha litšila.

Mekhoa ea Phekolo ea Cyanide - e nang le metsi a litšila

Phekolong ea cyanide - e nang le metsi a litšila indastering ea meepo ea khauta le melemo, re tseba mekhoa e fapaneng e butsoitseng le e sebetsang hantle:

• Alkaline Chlorination Mokhoa: Ena ke mokhoa o tloaelehileng oa ho senya Li-cyanides ka metsing a litšila a limela tsa khauta tsa cyanidation 'me e sebelisoa haholo ho hloekisa metsi a litšila a limela tsa cyanide electroplating, limela tsa khauta tsa cyanidation tsa khauta, limela tsa khauta tsa cyanidation le lihlopha tse ling. Molao-motheo oa eona ke ho sebelisa metsi a chlorine, khase ea chlorine kapa phofo e soeufatsang ho etsa oxidize cyanide metsing a litšila hore e be lintho tse seng chefo joalo ka carbon dioxide le nitrogen.

• Sulfur Dioxide - Mokhoa oa Oxidation oa Moea: E boetse e tsejoa e le mokhoa oa InCo, e entsoe ke American InCo Metals Company mathoasong a lilemo tsa bo-1980. Mokhoa ona o sebelisa sulfur dioxide le moea e le li-oxidant ho oxidize cyanides metsing a litšila tlas'a boemo ba koporo - ion catalyst, e hlahisang bicarbonate le ammonium ferrous sulfate. E ke ke ea tlosa feela li-ion tsa cyanide tsa mahala, hydrogen ea molek'hule le li-cyanides tse rarahaneng, empa hape e felisa li-complexes tsa ferrocyanide tseo ho leng thata ho li tlosa ka mokhoa oa chlorination, ho etsa hore metsi a litšila a hloekisitsoeng a finyelle litekanyetso tsa ho ntša metsi.

• Hydrogen Peroxide Oxidation Mokhoa: E loketse ho phekola cyanide e tlaase - e nang le metsi a litšila. Tlas'a ketso ea koporo - ion catalyst ka alkaline pH boleng ba 10 - 11. hydrogen peroxide oxidizes cyanides ho hlahisa lintho tsa lik'hemik'hale tse kang oxides le ammonium ferrous sulfate. Har'a tsona, li-ion tsa heavy metal li etsa hydroxide precipitates, 'me li-ion tsa ferrocyanide le li-ion tse ling tse boima li etsa matsoai a rarahaneng a ferrocyanide.

• Mokhoa oa Ozone Oxidation: E loketse ho phekola cyanide e batlang e hlapolla - e nang le mokelikeli o litšila. Ka alkaline pH boleng ba 11 - 12. ozone e oxidize cyanides ho hlahisa bicarbonate le nitrogen. Le hoja mokhoa ona o sitoa ho tlosa li-complexes tsa ferrocyanide, o na le melemo ea ho ba bonolo le ho ba bonolo. Ha ho hlokahale ho reka le ho tsamaisa lik'hemik'hale, 'me ho hlokahala feela jenereithara ea ozone ho phekola cyanide - e nang le metsi a litšila. Leha ho le joalo, e boetse e na le mefokolo ea tšebeliso e phahameng ea matla le litšenyehelo tse phahameng tsa phekolo. E le ho rarolla bothata ba li-complexes tsa ferrocyanide, Setsi sa Sesole sa Moeeng sa Tinker United States se ile sa qapa mokhoa o kopaneng oa ultraviolet photolysis le mokhoa oa ozone ’me oa e hlahloba ka katleho. Hamorao, mokhoa o tšoanang oa O3/photolysis o ile oa boela oa hlahisoa.

Tiisetso ea Lipalangoang le Polokelo

Sehokelong sa lipalangoang, re na le lisebelisoa tsa lipalangoang tsa lik'hemik'hale tse kotsi le lits'ebetso tse thata tsa taolo ea lipalangoang ho netefatsa hore sodium cyanide e fihla moo e eang e bolokehile ha e ntse e fokotsa tšusumetso tikolohong tseleng. Mabapi le polokelo, re fana ka tharollo ea polokelo ea mahlale le lisebelisoa ho thibela likotsi tse kang ho lutla ho silafatsa mobu le mehloli ea metsi. Maemong a sa lebelloang, re boetse re na le litsebi tsa theknoloji ea kalafo ea tšohanyetso le lihlopha tse ka arabelang kapele le ho fokotsa tšenyo ea tikoloho.

Shaanxi United Chemical e ikemiselitse ho sebetsa ka matsoho le balekane ba Kazakhstan ho fihlela nts'etsopele e tala le e tsitsitseng ha ba ntse ba fana ka lihlahisoa tsa boleng bo holimo tsa sodium cyanide. Re lumela hore ka boiteko ba rona, re ka kenya letsoho ntlafatsong ea indasteri ea Kazakhstan hape re eketsa tiisetso bakeng sa ts'ireletso ea tikoloho ea lehae.
