Izimayini

Ukusetshenziswa Kobuchwepheshe Bamuva Ekuhloleni Izimayini Ukuhlola izimayini kuyisigaba esibalulekile ngaphambi kokuba kuqale ukumba. Phakathi nalesi sigaba, izinkampani zilwela ukuthola, ukulinganisa, nokuhlola ngokunembile amandla ezimayini noma izinsiza zamalahle. Izinselele zibalulekile: izindawo ezinkulu, izimo zomhlaba ezimbi kakhulu, ukungaqiniseki kwezakhi zofuzo, izindleko zokusebenza eziphakeme, kanye nesidingo semisebenzi ephephile... Funda kabanzi

Amasu Okumba Emigodini Yegolide Engaphansi Komhlaba Ukumba igolide engaphansi komhlaba kuwukukhipha amaminerali ekujuleni okuthile ngaphansi kobuso boMhlaba, ngokuvamile ngenxa yokuthi amadiphozithi egolide atholakala emithanjeni emincane, emizimbeni yensimbi eqinile, noma ezimweni zejiyoloji ezenza ukumba imigodi evulekile kungabi nenzuzo. Ezinhlelweni zokumba ngaphansi komhlaba, ukumba kuba… Funda kabanzi

Izimiso Nezindlela Zokumba Ezimweni Ezinzima Kakhulu Zokumba Ukumba ezimweni ezimbi kakhulu zokumba kuyinselele enezici eziningi edinga ukunemba kobuchwepheshe, ukuziphatha okuphephile okuphezulu, kanye nokuzivumelanisa nobuchwepheshe okusheshayo. Igama elithi "ukumba okukhulu" libhekisela ezindaweni zamadwala kanye nezakhiwo zokumba ezibeka izingozi ezinkulu ekuzinzeni kwemithambeka, ukuphepha kokuvulwa kwemigodi, ukuqhubeka kokusebenza, kanye nemiphumela yemvelo. Izibonelo zifaka phakathi… Funda kabanzi… Funda kabanzi

Ukuhlaziywa Nokuqapha Ikhwalithi Yomoya Ezindaweni Zezimayini Izindawo zezimayini ziyizikhungo zomsebenzi wezimboni ezinamandla amakhulu okuthinta ikhwalithi yomoya. Ukuhlanzwa komhlaba, ukubhoboza, ukuqhumisa, ukulayisha nokuthutha izinto, kanye nokucubungula amaminerali kungadala ukukhishwa kwezinhlayiya negesi okuthinta impilo yabasebenzi, imiphakathi ezungezile, kanye nemvelo. Ngakho-ke, ukuhlaziywa nokuqapha… Funda kabanzi

Izidingo Zamandla Ekucubungulweni Kwamaminerali Ukucubungulwa kwamaminerali uchungechunge lwezinqubo zokuhlukanisa amaminerali abalulekile ekungcoleni (i-gangue), ukwandisa izinga lawo, nokukhiqiza imikhiqizo ehlangabezana nezimfuneko zezimboni. Ngemuva kwale migomo, kunesici esisodwa esinqumayo esivame ukunakwa: amandla. Izidingo zamandla ekucubungulweni kwamaminerali azithinti nje kuphela izindleko zokusebenza kodwa futhi... Funda kabanzi

Amasu Okunciphisa Umthelela Emvelweni Emisebenzini Yezimayini Imisebenzi yezimayini idlala indima ebalulekile ekuhlinzekeni ngezinto zokusetshenziswa emikhakheni eyahlukene, kusukela kumandla nokwakha kuya kubuchwepheshe. Kodwa-ke, naphezu kwalezi zinzuzo zomnotho, ukumbiwa kwezimayini nakho kunezingozi ezinkulu zemvelo. Imiphumela efana nokuwohloka komhlaba, ukungcola kwamanzi nomoya, ukulahlekelwa yizinto eziphilayo, kanye nokuphazamiseka komphakathi kungenzeka uma... Funda kabanzi

Ukuphathwa Kokudonswa Kwemigodi Yezimayini Ezine-asidi Emisebenzini Yezimayini Ukudonswa kwemigodi yezimayini ezine-asidi (i-AMD) kungenye yezinkinga ezibaluleke kakhulu zemvelo emisebenzini yezimayini, ikakhulukazi ezimayini zamalahle nasezimayini zensimbi eziqukethe inani elikhulu lamaminerali e-sulfide. I-AMD yakheka lapho amaminerali e-sulfide—njenge-pyrite (FeS₂)—evezwa emoyeni (i-oxygen) nasemanzini, bese ebhekana nokusabela kwe-oxidation okukhiqiza i-sulfuric acid. Lesi simo sibangela… Funda kabanzi

Amasu Nezindlela Zokucubungula Igolide Ezivela Ku-Ore Ukucubungula igolide kusuka ku-ore kuwuchungechunge lwezinqubo zobuchwepheshe zokuhlukanisa nokuhlanza igolide ezintweni zamatshe eziqukethe amaminerali ayigugu. Ngenxa yokuthi igolide ngokuvamile alitholakali ngesimo "esimsulwa" esitholakala kalula emvelweni, kudingeka izindlela eziqondile—kusukela ekulungiseleleni i-ore, ukuhlukaniswa ngokomzimba, ukuhlanzwa, kuya ekuhlanzweni kokugcina. Lesi sihloko… Funda kabanzi

Izinqubo Zokuphepha Emsebenzini Ezindaweni Zokumba Ukuphepha nempilo emsebenzini (OHS) ezindaweni zokumba kuyisici esiyisisekelo futhi esingaxoxiswana ngaso. Imisebenzi yokumba ihilela ukusetshenziswa kwemishini esindayo, ukuqhumisa, ukumba, ukuthuthwa kwezinto, kanye nokucubungula kokuqala, konke okunezinga eliphezulu lezingozi ezingaba khona. Ngaphezu kwalokho, izimo zezwe ezinzima, isimo sezulu esibi kakhulu, kanye nokuchayeka othulini namakhemikhali kwenza... Funda kabanzi

Indima Yezinhlelo Zolwazi Lwendawo Ezimbiweni Izimayini ziwumkhakha othembele kakhulu kudatha: kusukela endaweni, indawo, izindawo zokugcina, indawo ezungezile, ingqalasizinda, kanye nemisebenzi yansuku zonke yokusebenza. Phakathi kwezidingo zokusebenza kahle, ukuphepha, kanye nokuhambisana nemithethonqubo yezemvelo, izinkampani zezimayini zidinga izindlela ezinembile zokuphatha, ukuhlaziya, kanye nokwethula lolu lwazi.
