Impembelelo yoZinzo kuShishino lwezeMigodi

I-COP26, i-net-zero ekujoliswe kuyo, kunye nokutshintsha okukhawulezileyo ukuya kuzinzo olukhulu kuneempembelelo ezinzulu kushishino lwemigodi. Kuluhlu lwee-Q&As, sixoxa ngemingeni enxulumene namathuba. Siqala ngokujongisisa ubume bomhlaba obukhoyo kweli shishini libaluleke kakhulu kwihlabathi, kunye no-Ellen Thomson, iPGNAA kunye neNgcali yeSicelo esiPhezulu seMineral eThermo Fisher Scientific.

Asisoloko sibona iithagethi ezihambelana ngokuthe ngqo nemigodi, ngaphaya kwenjongo ekwabelwana ngayo ye-net-zero. Ngaba kukho izibophelelo ezithile ezivela kwi-COP26 eziya kubachaphazela abasebenzi-mgodini?

Ndicinga ukuba kulungile ukutsho ukuba, ngokubanzi, kukho uxabiso olungaphantsi kwendlela engundoqo ngayo imigodi kwiinzame zethu ezihlangeneyo ezisingise kwihlabathi lamandla azinzileyo, acocekileyo.

Thatha izibophelelo ze-COP26 malunga nezothutho - ukunqunyulwa kuka-2040 kuzo zonke iintengiso zeemoto ezintsha zibe yi-zero-emissions (2035 kwiimarike eziphambili)1. Ukufezekisa ezo thagethi kuxhomekeke ekonyuseni kakhulu ukuhanjiswa kwe-cobalt, i-lithium, i-nickel, i-aluminiyam, kwaye, ngaphezu kwayo yonke, ubhedu. Ukurisayikilishwa kwakhona akuyi kuhlangabezana nale mfuno ‒ nangona ukurisayikilisha okusebenzayo ngakumbi kubalulekile ‒ ngoko ke kufuneka sikhuphe iintsimbi ezininzi emhlabeni. Kwaye libali elifanayo elinamandla avuselelekayo, elijikeleze ngokuphindwe kahlanu ngaphezulu kobhedu kunolunye oluqhelekileyo2.

Ngoko ewe, abavukuzi bajongene nemingeni efanayo njengamanye amashishini ngokubhekiselele ekubetheni i-net-zero ekujoliswe kuyo, ukunciphisa impembelelo yokusingqongileyo, kunye nokuphucula ukuzinza, kodwa ngokuchasene ne-backdrop yeemveliso zabo zibaluleke kakhulu ekuphunyezweni kwezinye iithagethi ezininzi zokuzinza.

Kuya kuba lula kangakanani ukumisa izixhobo zentsimbi ukuhlangabezana nemfuno ekhulayo?

Sithetha ngokunyuka okukhulu kunye nokuzinzileyo, ngoko akuyi kuba lula. Ngobhedu, umzekelo, kukho uqikelelo lokunqongophala kwe-15 yezigidi zeetoni ngonyaka ngo-2034, ngokusekelwe kwimveliso yangoku yasemgodini3. Imigodi emidala kuya kufuneka ixhatshazwe ngokupheleleyo, kwaye iidiphozithi ezintsha zifunyenwe kwaye ziziswe kumlambo.

Nokuba yeyiphi na indlela, oku kuthetha ukusetyenzwa komgangatho ophantsi we-ore ngokufanelekileyo ngakumbi. Iintsuku zentsimbi ekrwada ene-2 ​​okanye i-3 % yoxinaniso lwentsimbi ziphelile ubukhulu becala, njengoko ezo ntsimbi ziphelile ngoku. Abasebenzi basemgodini wobhedu ngoku baqhele ukujongana noxinzelelo lwe-0.5 %. Oku kuthetha ukucubungula amatye amaninzi ukufikelela kwimveliso efunekayo.

Abasebenzi basezimayini bakwajongana nokuphononongwa okukhulayo ngokubhekiselele kwilayisensi yentlalontle yokusebenza. Kukho ukunyamezelwa okuncinci kokuhla kwemigodi - ukungcoliseka okanye ukuphela kokunikezelwa kwamanzi, impembelelo engabonakaliyo kwaye enokuthi ibe yingozi ye-tailings, kunye nokuphazamiseka kokunikezelwa kwamandla. Uluntu ngokungathandabuzekiyo lujonge kushishino lwezimayini ukuhambisa isinyithi esifunekayo kodwa ngaphakathi kwendawo esebenza nzima. Ngokwesiko, imigodi ibe lishishini elilambele amandla, amanzi amaninzi kunye nokungcola, kunye neendawo ezinkulu zokusingqongileyo. Ezona nkampani zigqwesileyo ngoku zenza izinto ezintsha ngesantya sokuphucula kuzo zonke iinkalo.

Ngawaphi amacebo ocinga ukuba aya kuba luncedo kakhulu kubasebenzi-mgodini xa kufikelelwa ekuhlangabezaneni nemingeni abajongene nayo?

Nangona kungekho mathandabuzo okuba abasebenzi basezimayini bajongene nemingeni enzima, enye imbono yeyokuba imbonakalo yomhlaba yangoku inika amathuba awodwa otshintsho. Ngemfuno ekhuselekileyo, kukho amandla amakhulu okuphucula, ngoko akuzange kube lula ukuthethelela uphuculo kwiindlela ezingcono zokusebenza. Itekhnoloji ekrelekrele ngokungathandabuzekiyo iyindlela eya phambili, kwaye kukho umdla wayo.

Ifanelekile, ithembekileulwazi lwedijithali lilitye lembombo lokusebenza ngokufanelekileyo kwaye kaninzi liyasilela. Ngoko ke ndingagxininisa utyalo-mali kuhlalutyo olusebenzayo noluqhubekayo njengesicwangciso esingundoqo sempumelelo. Ngedatha yexesha langempela, abasebenzi basezimayini banakho a) ukwakha ukuqonda okuqinileyo kokuziphatha kwenkqubo kunye b) nokuseka phambili, ulawulo lwenkqubo oluzenzekelayo, ukuqhuba uphuculo oluqhubekayo ngokusebenzisa ubuchule bokufunda ngomatshini. Le yenye yeendlela eziphambili esiya kuthi sitshintshele kwimisebenzi ehambisa ngakumbi ‒ ukukhupha isinyithi esingakumbi kwitoni nganye yamatye - ukunciphisa amandla, amanzi, kunye negalelo lekhemikhali.

Yeyiphi ingcebiso jikelele onokuthi uyinike abasebenzi basezimayini njengoko beqala inkqubo yokuchonga itekhnoloji kunye neenkampani ezinokubanceda?

Ndingathi ujonge iinkampani ezibonisa ukuqonda okuneenkcukacha kwimiba yakho kunye nendlela itekhnoloji yabo enokunceda ngayo. Khangela iimveliso ezinerekhodi elisekiweyo, esongelwe ngobuchule. Kwakhona, khangela abadlali beqela. Ukuphucula ukusebenza kakuhle kwemigodi kuya kuthatha i-ecosystem yababoneleli beteknoloji. Ababoneleli kufuneka baqonde igalelo labo elinokubakho, kunye nendlela yokunxibelelana ngokufanelekileyo nabanye. Kwakhona kubalulekile ukuba babelane ngemilinganiselo yakho. Inyathelo lokuJonga eliSekwe kwiNzululwazi (i-SBTi) sisiqalo esilungileyo ukuba ujonge iinkampani ezimisela izindlu zazo ngolungelelwaniso lozinzo, ngokusebenzisa imigangatho enokumetwa nefuna ngamandla.

Iimveliso zethu zabasebenzi basezimayini zimalunga nesampulu kunye nomlinganiselo. Sinikezela ngeesampulu, i-cross-belt kunye ne-slurry analyzers, kunye nezikali zebhanti ezihambisa umlinganiselo we-elemental kunye nokulandeleka ngexesha langempela. Ezi zisombululo zisebenza kunye, umzekelo, ukunika ulwazi olufunekayo ekugxininiseni kwentsimbi kwangaphambili okanye ukuhlela. Ukuhlela intsimbi ekrwada kuvumela abasebenzi basezimayini ukuba baxube intsimbi ekrwada engenayo ngokunempumelelo ngakumbi, baphumeze ulawulo lwenkqubo yokutya phambili, kunye nendlela yemathiriyeli yodidi olusezantsi okanye olukwinqanaba elisezantsi kude nesigxininisi ngokukhawuleza. Uhlalutyo lwexesha lokwenyani luxabisekile ngendlela ehambelana ne-concentrator ye-metallurgical accounting, ulawulo lwenkqubo okanye ukulandelela ukungcola okuxhalabisayo.

Ngezisombululo zokulinganisa ixesha lokwenyani, kuyenzeka ukuba kwakhiwe iwele ledijithali lomsebenzi wokumbiwa kwemigodi - ingqikelelo esidibana nayo ngokunyuka rhoqo. Iwele ledijithali yinguqulelo yedijithali epheleleyo, echanekileyo yesigxininisi. Nje ukuba unayo, ungazama ukulungelelanisa, kwaye ekugqibeleni, ukulawula ukude i-asethi kwidesktop yakho. Kwaye mhlawumbi ngumbono olungileyo wokukushiya ukusukela oko kuzenzekela, imigodi engenabantu ngokuqinisekileyo ingumbono wekamva. Ukufumana abantu emigodini kubiza imali eninzi, kwaye ngobugcisa obunobulumko nobuthembekileyo obuxhaswa lulondolozo olukude, akusayi kuba yimfuneko kumashumi eminyaka ezayo.
