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 meholo. Khamphani e tsetela mehloli e mengata lipatlisisong le nts'etsopele ea theknoloji, 'me e fana ka tšehetso e felletseng ea tekheniki bakeng sa mathata a ka bang teng a tikoloho a ka hlahang nakong ea tlhahiso, lipalangoang, polokelo le ts'ebeliso ea 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 ea litšila ho tsoa mohloling. Mohlala, ts'ebetsong ea tlhahiso, re amohela mahlale a tsoetseng pele a ho kopanya botala ho ntlafatsa ts'ebeliso ea thepa e tala le ho fokotsa mesi e tsoang litšilang.

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:

• Mokhoa oa ho Sebelisa Chlorine ea Alkaline : Ena ke mokhoa o tloaelehileng oa ho senya Cyanides metsing a litšila a limela tsa cyanidation tsa khauta 'me o sebelisoa haholo kalafong ea metsi a litšila a limela tsa cyanide tsa electroplating, limela tsa cyanidation tsa morafo oa khauta, limela tsa cyanidation tsa khauta le li-unit tse ling. Molao-motheo oa eona ke ho sebelisa chlorine e metsi, khase ea chlorine kapa phofo ea bleaching ho kopanya cyanide metsing a litšila hore e be lintho tse seng chefo tse kang carbon dioxide le naetrojene.

• Mokgwa wa ho Oxidation ya Sebabole - Mokgwa wa ho Oxidation ya Moya : O tsejwang hape e le mokgwa wa InCo, o ntshetswa pele ke Khamphani ya Amerika ya InCo Metals mathoasong a bo-1980. Mokgwa ona o sebedisa sulfur dioxide le moya e le di-oxidant ho oxidation ya cyanides metsing a ditshila tlasa boemo ba catalyst ya koporo le ion, e hlahisang bicarbonate le ammonium ferrous sulfate. Ha o kgone feela ho tlosa di-ion tsa cyanide tse lokolohileng, haedrojene ya dimolek'hule le cyanides tse rarahaneng, empa hape o ka fedisa di-complex tsa ferrocyanide tse thata ho di tlosa ka mokgwa wa chlorination, e leng se etsang hore metsi a ditshila a phekotsweng a fihlelle maemo a ho ntsha metsi.

• Mokhoa oa ho Oxidation ea Hydrogen Peroxide : E loketse ho phekola metsi a litšila a nang le cyanide e nang le mahloriso a tlase. Tlas'a ts'ebetso ea catalyst ea koporo-ion ka boleng ba alkaline pH ba 10 - 11, hydrogen peroxide e oxidation ea cyanides ho hlahisa lintho tsa lik'hemik'hale tse kang li-oxide le ammonium ferrous sulfate. Har'a tsona, li-ion tsa tšepe e boima li etsa li-hydroxide precipitates, 'me li-ion tsa ferrocyanide le li-ion tse ling tsa tšepe e boima li etsa letsoai le rarahaneng la ferrocyanide.

• Mokhoa oa ho Oxidation oa Ozone : E loketse ho phekola cyanide e nang le mokelikeli o litšila o fokolang. Ka boleng ba pH ea alkaline ea 11 - 12, ozone e oxidation ea cyanides ho hlahisa bicarbonate le naetrojene. Le hoja mokhoa ona o sa khone ho tlosa metsoako ea ferrocyanide, o na le melemo ea ho nolofatsa le ho nolofatsa. Ha ho hlokahale ho reka le ho tsamaisa lik'hemik'hale, 'me ho hlokahala jenereithara ea ozone feela ho phekola metsi a litšila a nang le cyanide. Leha ho le joalo, e boetse e na le mathata a tšebeliso e phahameng ea matla le litšenyehelo tse phahameng tsa kalafo. Ho rarolla bothata ba metsoako ea ferrocyanide, Setsi sa Sesole sa Moeeng sa Tinker United States se ile sa theha mokhoa o kopaneng oa photolysis ea ultraviolet le mokhoa oa ozone 'me sa o leka ka katleho. Hamorao, mokhoa o tšoanang oa O3/photolysis le oona o ile oa ntlafatsoa.

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.
