Ukuqonda iiNdlela zeMarike yeSodium Cyanide kwiNgingqi yase-Afrika

Ukwandiswa kweMbango kwiMisebenzi yeMigodi yeGolide

Ishishini lemigodi yegolide belisoloko liyimbangela ephambili yemfuno ye- sodium cyanide eAfrika. I-Afrika kancinci kancinci iba liziko elibalulekileyo lemisebenzi yemigodi yehlabathi. Kwinkqubo yeekhemikhali yokukhupha igolide , i-Sodium Cyanide idlala indima ebalulekileyo kwinkqubo yokukhupha . Kule nkqubo, i-ore iyatyunyuzwa ibe ngumgubo ocolekileyo ize iphathwe ngesisombululo se -Sodium cyanide ukwenza iikhompawundi zegolide ezinyibilikayo emanzini. Xa kuthelekiswa nezinye iindlela zokukhupha ezinye, le nkqubo ithandwa kakhulu ngenxa yokuphila kwayo ngokwezoqoqosho, ukulula kokusebenza, kunye nokuzinza kokusingqongileyo. Ngo-2021, ishishini lemigodi yegolide e-Afrika libonise amandla amakhulu, ngemveliso yegolide yeetoni ezingama-680.3. Phakathi kwazo, iGhana yaba ngumthengisi wesibini ngobukhulu wegolide e-Afrika ngo-2022, ngemveliso yeetoni ezimalunga nama-90.

INtshona Afrika ibe yindawo ephambili yokukhangela igolide. Ngenxa yokuba uninzi lwezixhobo zayo zezimbiwa azikaphuhliswa, itsale utyalo-mali olukhulu lwamazwe ngamazwe. Uphuhliso oluqhubekayo lweziseko zophuhliso lwemigodi kulo mmandla lubonakala kwipotifoliyo yayo emangalisayo yeeasethi zegolide, kubandakanya iiprojekthi ezingama-367 kwinqanaba lokuhlola, iiasethi ezingama-24 eziphantsi kovavanyo loqoqosho, kunye neeasethi ezingama-61 kwisigaba sokuvelisa okanye sokwakha. Imisebenzi emikhulu yokwemba efana nomgodi wegolide waseSouth Deep, umgodi wegolide waseKromdraai, kunye nomgodi wegolide waseMponeng eMzantsi Afrika iqhubeka nokuqhuba imfuno ye-sodium cyanide kwiinkqubo zayo zokukhupha. Ubukho beenkampani ezininzi zemigodi zamazwe ngamazwe kunye nophuhliso oluqhubekayo lweeprojekthi ezintsha zemigodi buqinisa ngakumbi umbono wemfuno yee-reagents zemigodi kushishino lwemigodi yegolide kulo mmandla.

Ukwandiswa kweMfuno yokusetyenziswa kwiMichiza kunye nePolymer Synthesis

Ushishino lwemichiza lubalulekile ekusetyenzisweni kwesodium cyanide, ingakumbi eMzantsi Afrika, apho ishishini lemichiza lithatha malunga nama-25% entengiso yemveliso yelizwe. I-sodium cyanide (NaCN) inoluhlu olubanzi lwezicelo kwiinkqubo ezahlukeneyo zeekhemikhali, kubandakanywa ukuveliswa kweepolymers, i-cyanuric chloride, kunye ne-cyanogen chloride. Iziseko ezingundoqo ezomeleleyo zemizi-mveliso yaseMzantsi Afrika kunye nendawo yawo njengenye yeendawo eziphambili kushishino lweekhemikhali e-Afrika zibonelela ngenkxaso eyomeleleyo kuphuhliso loshishino lokwenziwa kwemichiza. Imithombo yobutyebi ekrwada eninzi kunye nokwanda kotyalo-mali lwangaphandle ngokuqhubekayo kudala inani elikhulu lamathuba okukhula kushishino lwemichiza kweli lizwe.

Ukwanda okuqhubekayo koshishino lweplastiki yokwenziwa kweplastiki e-Afrika kuphakamisa ngakumbi imfuno ye-sodium cyanide kwi-polymer synthesis kunye nezinye iindawo zokusetyenziswa kwemichiza. Ishishini lemichiza, njengecandelo elibalulekileyo elinyukayo kuwo omabini amashishini emigodi nezolimo, lidala isiseko semfuno eyohlukeneyo yeekhemikhali zokusetyenzwa kwegolide. Abavelisi bemichiza abakhulu abanjengoSasol, abasebenzisa amaziko okuvelisa i-sodium cyanide ngokuthobela iKhowudi yoLawulo lweCyanide yaMazwe ngaMazwe, baqhubeleka nokuhlangabezana nemfuno ekhulayo yokusetyenziswa kwemichiza eyahlukeneyo. Ukudityaniswa koshishino lweekhemikhali kunye namanye amacandelo emizi-mveliso, kubandakanywa unyango lwesinyithi, ukwenziwa kwedayi, kunye nokuveliswa kwemveliso ye-agrochemical, kuqhubela phambili ukuqhubela phambili ukusetyenziswa kwee-reagents zemigodi kwizicelo ze-chemical synthesis.

Kuyafaneleka ukukhankanya ukuba kwintsimi yokubonelela nge-sodium cyanide yehlabathi, uShaanxi United Chemical ivelele njengomnye wabavelisi abahamba phambili kunye nabanikezeli besodium cyanide. Inkampani ixhotyiswe ngeefektri zobungcali, ubugcisa bemveliso ephucukileyo, kunye neenkqubo ezingqongqo zokulawula umgangatho, kwaye iyakwazi ukubonelela abathengi ngomgangatho ophezulu kunye neemveliso zesodium cyanide ezifikelelekayo. Nokuba lishishini lemigodi yegolide okanye amasimi ekhemikhali kunye ne-polymer synthesis, Shaanxi United Chemical inokuhlangabezana neemfuno ezahlukeneyo zabathengi abahlukeneyo kunye neemveliso zayo ezikumgangatho ophezulu kwaye inegalelo kuphuhliso lwamashishini ahlukeneyo.
