Iphando Lokucubungula Ikuhli leNcibilikayo

2025-12-16

Isiphetho:Umhlahlandlela ophelele ophathelene nezinhlobo ze-copper ore, izinhlu zomhlaba, nedatha yokukhiqiza, umkhiqizo wezinhlelo zokucubungula i-copper ore, ukuhamba komsebenzi wokwakha, izindlela ezijwayelekile zokusebenza, kanye nokuphuma kwamandla ngemuva kokucubungula ukuze kukhiqizwe insimbi ephumelelayo.

Ibhokisi, njengenhloko ebalulekile yomhlaba kanye nomsebenzi wezomnotho, kube umgogodla wempilo yabantu kusukela ezikhathini zakudala. Ezinhlelweni zemikhiqizo zanamuhla nezezimali, ibhokisi lisebenza hhayi kuphela njengempahla eyinhloko yokwakha ugesi, izakhiwo, nokukhiqiza kodwa futhi njengesinsiza esiyinhloko sokushintsha amandla, noveli yobuchwepheshe, kanye nentuthuko esimeme.

Ukusebenza kwayo okuhle kakhulu kokudlulisela ugesi, izakhi zofuzo zokushisa, umthamo, nokumelana nokugqwala kuveza ithusi njenge "Khosi Yezinsimbi" engaphuthelwa emsociety yanamuhla, kubonisa kokubili amathuba okukhula kanye nokumelana nezimo zokwehla phakathi kwezinguquko zomnotho omhlaba.

Izinhlobo ze-ore yensimbi yensimbi

Ikhuba likhona emvelweni ikakhulukazi njengezixhumi zom Minerals kwiindawo ezahlukene ze-copper, ngokungajwayelekile kubonakala kokwakhiwa okwenziwe ngensimbi (elemental). Ngokusekelwe ekwakhekeni kwemichiza nasemigqeni ye-crystal, imichiza ye-copper ingahlukaniswa ngezindlela ezilandelayo:

Ithusi le-Sulfide

Uhlobo lwezinto ezisemqoka ezisezitokisini zensimbi, oluthatha ngaphezu kuka-80% wokukhiqiza insimbi yomhlaba jikelele.

【Chalcopyrite (CuFeS2) 】

Ukubonakala:Iwebhu elithambile elinombala we-copper obomvu ohlinzekayo ongenakuvuthwa.

Izici ze-mineralogical:Itholakala kakhulu ezindaweni ze-copper ezikhanyayo. Isebenza ngokwezimali uma igcwele ngokwanele.

Ubuciko Bokuhleleka Kwekhava Emhlabeni Jikelele

Izinsiza zetshe elinama-global zikhombisa "ukuba khona okuphezulu, ukusabalala okukhangayo". Kusukela ngo-2024, ukuveliswa kwesikhathi sonyaka kufinyelele ~22.36 million tonnes nezinqolobane ezingu ~980 million tonnes. Abaphathi be-10 ephezulu bezinqolobane balawula u-75% wezinqolobane zomhlaba, kanti iChile ngokwayo inezinga elingu-19%; abadayisi abathathu abaphezulu (iChile, iPeru, iDRC) bangama-50% okukhiqizwa kwemikhiqizo emhlabeni jikelele. I-Afrika ivela njengephuzu elisha lokutshala izimali emigodini ngenxa yamandla amaminerali nezinqubomgomo ezinhle.
