Ixabiso lediphozithi yobhedu emiselweyo?

Zininzi izinto ekufuneka ziqwalaselwe xa kusenziwa isigqibo sexabiso lediphozithi yolawulo. Phakathi kwezinye izinto, iinkampani kufuneka zithathele ingqalelo iBakala, iindleko zokuhlaziya, izibonelelo zobhedu kunye nokukhululeka kokumbiwa kobhedu. Apha ngezantsi kukho isishwankathelo esifutshane sezinto ezininzi ekufuneka ziqwalaselwe xa kusenziwa isigqibo sexabiso lediphozithi yolawulo.

Zeziphi iintlobo zeediphozithi zobhedu?

Iidiphozithi ze-Perphyry Popper zikwinqanaba eliphantsi kodwa zingumthombo obalulekileyo wobhedu kuba zinokubethwa kwinqanaba eliphezulu ngeendleko eziphantsi. Ngokwesiqhelo baqukethe i-0.4% ukuya kwi-1% yobhedu kunye neemali ezincinci kwezinye izinyithi ezinjenge molybdenum, isilivere negolide. Iidiphozithi ze-porphyry ze-porphyry zihlala zikhulu kwaye zikhutshiwe kwimigodi yemoto evulekileyo.

I-sedarintle ye-sediment ye-sediment ye-sediment yelolona hlobo lubalulekileyo lweediphozithi zobhedu, i-accounting malunga nekota enye yediphozithi yeHlabathi yeHlabathi.

Ezinye iintlobo zeedipozithi zobhedu ezifunyenwe kwihlabathi liphela zibandakanya:

I-VolcaNgenic enkulu ye-SulCanogen Sulfide (VMS) i-vissits yimithombo ye-sulfer ye-calper eyenziwe ngezehlo ze-hydrothermal kwiindawo ezinamatshizi.

I-Iron Axide-Copper-Coper-Gold (iOCG) i-Idibets ixabiseke kakhulu yexabiso lobhedu, igolide kunye ne-Uranium.

Iidipozithi zobhedu, zithetha ngokubanzi, zenziwa ngekhemikhali kunye nokuthathwa komzimba okwenzeka emzimbeni okwenzeka xa zimbini izinto ezahlukeneyo ze-lathologies zinxibelelana.

Ithini inqanaba le-ovaliweyo lezixhobo zobhedu?

Ibakala liyinto ebalulekileyo kwixabiso ledipozithi yeminerali kwaye ngumlinganiselo ophumelelayo wokuguqulwa kwentsimbi. Uninzi lwe-oresper ores iqukethe kuphela inxenye encinci yentsimbi yobhedu kwiiminerals exabisekileyo. Elinye i-ore ye-ore lilitye nje elingafunekiyo.

Iinkampani zokuhlola ziqhuba iinkqubo zokuqhuba ukukhupha iisampulu zamatye abizwa ngokuba yi-cores. I-core ke yohlalutyiwe ngokulinganayo ukufumanisa "iBanga" lediphozithi.

Inqanaba lediphozithi yobhedu ihlala ibonakaliswa njengezisindo kwilitye elipheleleyo. Umzekelo, iikhilogram ezili-1000 ze-oreper ore ineekhilogramu ezingama-300 zensimbi ye-Popper enenqanaba lama-30%. Xa uxinzelelo lwentsimbi lusezantsi kakhulu, lunokuchazwa ngokwemigaqo yenxalenye yesigidi. Nangona kunjalo, iBakala yiNgqungquthela yesiqhelo ukuze yobheduzo, kunye neenkampani zokuhlola ziqikelela umgangatho ngokuzimela kunye ne-assay.

Ibanga eliqhelekileyo lobhedu lwe-ore le-ore kule nkulungwane yama-21 lingaphantsi kwe-0.6%, kunye nenani leeminerali ze-ore kwi-Ore ye-ORE ingaphantsi kwe-2%.

Abatyalomali kufuneka babonelele ngoqikelelo lwebanga elineliso eliqaqambileyo. Xa inkampani ehlolayo ikhupha ingxelo yeBanga, abatyali-mali kufuneka baqiniseke ukuba bathembisa ngokupheleleyo kubunzulu be-rill osetyenziselwa ukumisela ibanga. Ixabiso lebakala eliphezulu kubunzulu obuphantsi lingaphantsi kakhulu kunexabiso lamabanga aphakathi ahambelana ngokulinganayo.

Ixabisa malini kobhedu?

Ezona migodi zoshicilelo zikhulu kwaye uninzi lweemigodi ezivulekileyo, nangona imigodi engaphantsi komhlaba ayiqhelekanga. Eyona nto ibaluleke kakhulu kwi-hin hin i-hin i-hin ngumthombo obonakalayo kufutshane nomphezulu.

Iinkampani zemigodi zinomdla ikakhulu kwinani eligqithisileyo, elililitye elingento yanto kunye nomhlaba ngaphezulu komthombo wobhedu. Ezi zixhobo kufuneka zisuswe ukufikelela kwizixhobo. I-Escondida, ekhankanywe apha ngasentla, inezixhobo ezigutyungelwe zizinto ezibanzi, kodwa idipozithi isenexabiso lezoqoqosho ngenxa yexabiso elikhulu lezixhobo eziphantsi komhlaba.

Zithini iindidi zemigodi yobhedu?

Zimbini iintlobo ezahlukeneyo zediphozithi yobhedu Okwangoku, eyona mthombo uqhelekileyo ye-oreper ore yi-chalfide chalcopcrite, echaza malunga ne-50% yemveliso yobhedu. I-ores ye-sulfide iqhubekiswa ngefloti ye-ruth ukufumana ucofe ugxininiso. I-Oresper ores equkethe i-chalcopcprite inokuvelisa igxile kwi-20% ukuya kwi-30% yobhedu.

The more valuable chalcocite concentrates are usually of higher grade, and since chalcocite contains no iron, the copper content in the concentrate ranges from 37% to 40%. I-Chalcocite incinci kangangeenkulungwane kwaye yenye yezona ziholi zobhedu. Isizathu soku ngumxholo wayo ophezulu, kwaye ubhedu luye lwahlukaniswa ngokulula kwi-sulfure.

Nangona kunjalo, ayisiyonto enkulu yobhedu namhlanje. I-Copper Oxide ihlawulwe nge-sulfuric acid, ukukhupha izimbiwa zobhedu zibe sisisombululo se-acid i-SulFuric sithwele isisombululo se-sulper. Ubhedu emva koko luphakelwe kwisisombululo se-sulfate (ebizwa ngokuba sisisombululo esityebileyo) ngomgaqo we-solvent kunye nenkqubo yokutshona kwezixhobo e-elektroniki, enoqoqosho ngakumbi kunefloti yefreyiti.
