Ukuqonda iiNdlela zeMarike yeSodium Cyanide kwiNgingqi yase-Afrika

Ukwandiswa kweMbango kwiMisebenzi yeMigodi yeGolide

The ukumbiwa kwegolide ishishini ibisoloko ingumqhubi ophambili wemfuno sodium cyanide eAfrika. I-Afrika ngokuthe ngcembe iba liziko elibalulekileyo lemisebenzi yemigodi yehlabathi. Kwinkqubo yemichiza ye ukutsalwa kwegolide, Isodium cyanide idlala indima ebalulekileyo nge inkqubo leaching. Kule nkqubo, intsimbi ekrwada iyatyunyuzwa ibe ngumgubo ocolekileyo kwaye emva koko iphathwe nge Isodium cyanide isisombululo sokwenza amanzi - iikhompawundi zegolide ezinyibilikayo. Xa kuthelekiswa nezinye iindlela zokutsalwa, le nkqubo ithandwa kakhulu ngenxa yoqoqosho lwayo, ukusebenza ngokulula, kunye nokuzinza kwendalo. Ngo-2021. ishishini lemigodi yegolide e-Afrika libonise ukomelela olomeleleyo, kunye nemveliso yegolide yeetoni ezingama-680.3 zeemetric. Phakathi kwabo, iGhana ibeyesibini - inkulu kumthengisi wegolide e-Afrika ngo-2022. ngemveliso yeetoni ezimalunga ne-90 zeemetric.

INtshona Afrika iye yaba yeyona ndawo iphambili yokuhlola igolide. Ngenxa yokuba uninzi lwemithombo yalo yezimbiwa ingekaphuhliswa, itsale isixa esikhulu sotyalo-mali kumazwe ngamazwe. Uphuhliso oluqhubekayo lweziseko ezingundoqo zemigodi kulo mmandla bubungqina kwisikhundla sayo esimangalisayo sempahla yegolide, kubandakanywa iiprojekthi ezingama-367 ezikwinqanaba lokuhlola, ii-asethi ezingama-24 eziphantsi kovavanyo loqoqosho, kunye nee-asethi ezingama-61 kwizigaba zemveliso okanye zokwakha. Imisebenzi yemigodi emikhulu efana nomgodi wegolide waseSouth Deep, umgodi wegolide waseKromdraai, kunye nomgodi wegolide waseMponeng eMzantsi Afrika uqhuba ngokuqhubekayo imfuno yesodium. i-cyanide kwiinkqubo zabo zokutsalwa. Ubukho beenkampani ezininzi zemigodi zamazwe ngamazwe kunye nophuhliso oluqhubekayo lweeprojekthi zemigodi ezintsha zomeleza ngakumbi imbonakalo yemfuno yezixhobo 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.
