Ho utloisisa Mekhoa ea 'Maraka ea Sodium Cyanide Lebatooeng la Afrika

Keketseho e Eketsehileng ea Mesebetsi ea Meepo ea Khauta

The meepo ea khauta indasteri esale e le mokhanni ea ka sehloohong oa tlhokahalo ea sodium cyanide Afrika. Afrika butle-butle e fetoha setsi sa bohlokoa sa mesebetsi ea merafo lefatšeng ka bophara. Ts'ebetsong ea lik'hemik'hale tsa ho ntsha kgauta, Sodium cyanide e bapala karolo ea bohlokoa ka ho mokhoa oa leaching. Ts'ebetsong ena, ore e siloa hore e be phofo e ntle ebe e phekoloa ka Sodium cyanide tharollo ea ho etsa metsi - metsoako ea khauta e qhibilihang. Ha ho bapisoa le mekhoa e meng e meng ea ho ntša, ts'ebetso ena e ratoa haholo ka lebaka la ts'ebetso ea eona ea moruo, ts'ebetso e bonolo, le ho tšoarella ha tikoloho. Ka 2021. indasteri ea merafo ea khauta Afrika e bontšitse matla a matla, ka tlhahiso ea khauta ea 680.3 metric tons. Har'a bona, Ghana e ile ea e-ba mofani oa bobeli - e moholo ka ho fetisisa oa khauta Afrika ka 2022. ka tlhahiso ea hoo e ka bang 90 metric tons.

Afrika Bophirimela e se e le sebaka se ka sehloohong sa ho batlisisa khauta. Ka lebaka la hore boholo ba mehloli ea eona ea lirafshoa e ntse e tla ntlafatsoa, ​​e hohetse matsete a mangata a machaba. Nts'etsopele e tsoelang pele ea meralo ea motheo ea merafo sebakeng sena e bonahala ho tsoa ho potefolio ea eona e tsotehang ea thepa ea khauta, ho kenyeletsoa merero e 367 boemong ba lipatlisiso, thepa e 24 tlas'a tlhahlobo ea moruo, le thepa e 61 mekhahlelong ea tlhahiso kapa ea kaho. Mesebetsi e meholo ea merafo e kang ea South Deep gold mine, Kromdraai gold mine, le Mponeng gold morafo Afrika Boroa li tsoela pele ho tsamaisa tlhokahalo ea sodium. cyanide mekhoeng ea bona ea ho ntša. Boteng ba lik'hamphani tse ngata tsa merafo tsa machaba le nts'etsopele e tsoelang pele ea merero e mecha ea merafo e matlafatsa le ho feta tebello ea tlhokahalo ea lisebelisuoa tsa merafo indastering ea merafo ea khauta sebakeng sena.

Tlhokahalo e Eketsehileng ea Tšebeliso ho Lik'hemik'hale le Polymer Synthesis

Indasteri ea lik'hemik'hale ke eona e susumetsang tšebeliso ea sodium cyanide, haholo-holo Afrika Boroa, moo indasteri ea lik'hemik'hale e etsang karolo ea 25% ea thekiso ea tlhahiso ea naha. Sodium cyanide (NaCN) e na le lisebelisoa tse ngata tse fapaneng lits'ebetsong tse fapaneng tsa lik'hemik'hale, ho kenyelletsa le ho etsa lipolymers, cyanuric chloride le cyanogen chloride. Mafaratlhatlha a a nonofileng a madirelo a Aforika Borwa le maemo a ona jaaka nngwe ya mafelo a magolo a intaseteri ya dikhemikale mo Aforika a tlamela ka tshegetso e e nonofileng mo tlhabololong ya intaseteri ya tlhagiso ya dikhemikale. Mehloli e mengata e tala le matsete a ntseng a eketseha a tsoang kantle ho naha a ntse a theha palo e kholo ea menyetla ea kholo bakeng sa indasteri ea lik'hemik'hale naheng ena.

Keketseho e tsoelang pele ea indasteri ea tlhahiso ea polasetiki Afrika e tsoela pele ho khothaletsa tlhokahalo ea sodium cyanide ho polymer synthesis le masimo a mang a ts'ebeliso ea lik'hemik'hale. Indasteri ea lik'hemik'hale, e le karolo ea bohlokoa e ka holimo ho liindasteri tsa merafo le tsa temo, e theha motheo oa tlhokahalo e fapaneng ea lik'hemik'hale tse lokisang khauta. Baetsi ba lik'hemik'hale tse kholo joalo ka Sasol, e sebetsang lits'ebetsong tsa tlhahiso ea sodium cyanide ho latela Khoutu ea Machaba ea Tsamaiso ea Cyanide, e tsoela pele ho fihlela tlhoko e ntseng e hola ea ts'ebeliso ea lik'hemik'hale tse fapaneng. Ho kopanngoa ha indasteri ea lik'hemik'hale le likarolo tse ling tsa indasteri, ho kenyeletsoa kalafo ea tšepe, tlhahiso ea dae, le tlhahiso ea lik'hemik'hale tsa temo, e tsoela pele ho khanna tšebeliso ea li-reagents tsa merafo lits'ebetsong tsa motsoako oa lik'hemik'hale.

Ho bohlokoa ho bolela hore tšimong ea phepelo ea sodium cyanide, Shaanxi United Chemical e hlahella e le e mong oa baetsi le barekisi ba ka sehloohong ba sodium cyanide. Khamphani e na le lifeme tsa profeshenale, mahlale a tsoetseng pele a tlhahiso, le litsamaiso tse thata tsa taolo ea boleng, 'me e khona ho fa bareki lihlahisoa tsa sodium cyanide tsa boleng bo holimo le tse theko e tlaase. Ebang ke indasteri ea meepo ea khauta kapa masimo a lik'hemik'hale le polymer synthesis, Shaanxi United Chemical e ka fihlela litlhoko tse fapaneng tsa bareki ba fapaneng ka lihlahisoa tsa eona tsa boleng bo holimo mme ea kenya letsoho ntlafatsong ea liindasteri tse fapaneng.
