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

Keketseho e Eketsehileng ea Mesebetsi ea Meepo ea Khauta

Indasteri ea merafo ea khauta esale e le eona e susumetsang tlhoko ea sodium cyanide Afrika. Afrika e ntse e fetoha setsi sa bohlokoa sa ts'ebetso ea merafo ea lefats'e. Ts'ebetsong ea lik'hemik'hale ea ho ntša khauta , Sodium Cyanide e bapala karolo ea bohlokoa ts'ebetsong ea ho ntša . Ts'ebetsong ena, lejoe le silakanngoa hore e be phofo e ntle ebe le phekoloa ka tharollo ea Sodium cyanide ho etsa metsoako ea khauta e qhibilihang ka metsing. Ha e bapisoa le mekhoa e meng ea ho ntša, ts'ebetso ena e ratoa haholo ka lebaka la ho phela ha eona moruong, bonolo ba ts'ebetso, le botsitso ba tikoloho. Ka 2021, indasteri ea merafo ea khauta Afrika e bontšitse matla a maholo, ka tlhahiso ea khauta ea lithane tse 680.3. Har'a tsona, Ghana e ile ea fetoha mofani oa bobeli oa khauta ka ho fetisisa Afrika ka 2022, ka tlhahiso ea lithane tse ka bang 90 tsa metric.

Afrika Bophirimela e se e le sebaka se seholo sa ho batlisisa khauta. Ka lebaka la hore boholo ba mehloli ea eona ea liminerale ha e so ntlafatsoe, e hohetse matsete a mangata a machabeng. Nts'etsopele e tsoelang pele ea meralo ea motheo ea merafo sebakeng sena e bonahala ho tsoa ho pokello ea eona e ikhethang ea matlotlo a khauta, ho kenyeletsoa le merero e 367 mohatong oa ho batlisisa, matlotlo a 24 a tlas'a tlhahlobo ea moruo, le matlotlo a 61 mekhahlelong ea tlhahiso kapa kaho. Mesebetsi e meholo ea merafo joalo ka morafo oa khauta oa South Deep, morafo oa khauta oa Kromdraai, le morafo oa khauta oa Mponeng Afrika Boroa e tsoela pele ho khanna tlhoko ea sodium cyanide lits'ebetsong tsa eona tsa ho ntša. Boteng ba lik'hamphani tse ngata tsa merafo tsa machaba le nts'etsopele e tsoelang pele ea merero e mecha ea merafo li matlafatsa tebello ea tlhoko bakeng sa li-reagent 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.
