Ndedzipi mhando dzemhangura mapepa aripo?

Porphyry Copper Confeits yakaderera-giredhi asi yakakosha sosi yemhangura nekuti dzinogona kunge dzinogona kuve dzakakura pane yakakura chiyero pamutengo wakaderera. Ivo vanowanzove ne1.4% kusvika 1% yemhangura uye madiki mimwe simbi dzakadai saMolybdenum, sirivheri nendarama. Porphyry Copper Deposits inowanzo gurwa uye inobviswa kuburikidza neyakavhurika pit mugic.

Copper-kutakura matombo emhando ndeye yechipiri yakanyanya kukosha mhando yemhangura deposits, accounting yeanenge chikamu chimwe chete chemahara yenyika yakawanikwa yemhangura.

Mamwe marudzi emhangura mapepa akawanikwa pasi rese anosanganisira:

Volcanogenic yakakura sulfide (vms) deposits iri masosi emhangura sulfide yakaumbwa kuburikidza neHydrothermal zviitiko nharaunda dzegungwa.

Iron Oxide-Copper-Goridhe (iocg) deposits yakakwirira-yakakosha-kukosha kwekukosheswa kwemhangura, goridhe uye uranium ores.

Copper Skarn deposits, kutaura zvakawanda, kunoumbwa kuburikidza nemakemikari uye mumuviri kushandurwa kwemaminerari zvinoitika kana maviri miviri lithologies inosangana.

Ndeipi iyo average yegiredhi regavhu renhema.

Giredhi chinhu chakakosha mukukosha kwechinguvana dhipoziti uye chiitiko chinoshanda chesimbi. Mazhinji emhangura maronda ane chikamu chidiki chete chesimbi yemhangura yakasungwa mune yakakosha ore zvicherwa. Iyo yese ore ingori dombo risingadiwe.

Makambani ekutsvaga anoitisa zvinomera zvirongwa zvekubvisa matanho emasampula anonzi cores. Iyo Core inozoongororwa nemakemikari kuti ione kuti "giredhi" reSipo.

Copper Deposit Giredhi inowanzoratidzwa sehuremu hwehuwandu hwedombo rakazara. Semuenzaniso, 1000 kilogiramu emhangura ore ine mazana matatu emakirogiramu emarara madiki ane giredhi makumi matatu muzana. Kana kusungwa kwesimbi kuri kuderera, kunogona kutsanangurwa maererano nezvikamu pamamiriyoni. Nekudaro, giredhi igungano rakajairika remhangura, uye makambani ekutsvaga fungidzira giredhi kuburikidza nekukwevera uye kufungidzira.

Avhareji yedanho redanho remhangura ore muzana ramakore rechi21 riri pasi pe 0.6%, uye chikamu che ore zvicherwa mune yakazara ORE vhoriyamu iri pasi pe2%.

Investors inofanirwa kuona giredhi fungidziro ine ziso rinotsoropodza. Kana kambani yekuongorora ichirovera chirevo chegiredhi, maInvesors anofanirwa kuve nechokwadi chekuzvienzanisa nekudzika kwakazara kwekurova kwekurova kwakashandiswa kuona giredhi. Iko kukosha kwegiredhi rakakwira pane yakaderera kudzika kwakadzika kupfuura kukosha kweiyo mediocre giredhi rinoenderana nepakati nepakati.

Zvakawanda sei mutengo kune wangu mhangura?

Iyo yakakura uye yakanyanya kuwana miti yemicheka yakavhurika-gomba-gomba mini, kunyangwe pasi pevhu remavhiri emicheka hazvisi zvisina kujairika. Chinhu chakanyanya kukosha mune yakavhurika gomba yangu ndiyo mari sosi iri padyo nepamusoro.

Makambani emigodhi anonyanya kufarira huwandu hwekunyanyisa, iyo ndiyo huwandu husina kukosha dombo uye ivhu riri pamusoro pemhangura. Izvi zvinyorwa zvinofanirwa kubviswa kuti uwane zviwanikwa. Escondida, ambotaurwa pamusoro, ane zviwanikwa zvakafukidzwa nekuwedzera nekuwedzeredza, asi dhipoziti ichine kukosha kwehupfumi nekuda kwehuwandu hwezviwanikwa pasi pevhu pasi pevhu pasi pevhu.

Ndedzipi mhando dzemavhangu emicheka?

Kune maviri akasiyana marudzi emhando yemhangura: Sulfide ores uye oxide ores. Parizvino, iyo yakajairika sosi yemhangura ore ndiyo sulfide mineral chalcopyrite, iyo inokonzeresa inosvika makumi mashanu muzana yekugadzira mhangura. Sulfide ores inogadziriswa kuburikidza nejasi kuronga kuwana mhangura popper conentrate. Mhangura maOres ane charcopyrite inogona kuburitsa maonomisa ane 20% kusvika 30% yemhangura.

Iyo inonyanya kukosha calcocite inowanzoita seyakakwira giredhi, uye sezvo charcocite isina iron, iyo mhangura mumaronda anobva ku37% kusvika pa40%. Chalcocite yakave yakavezwa kwemazana emakore uye ndeimwe yeiyo inobatsira mhangura yemhangura. Chikonzero cheiyi ndiyo yakakwirira yemhangura yemhangura, uye iyo mhangura yarimo inoparadzaniswa nepamhepo.

Nekudaro, haisi iyo huru yemhangura yangu nhasi. Copper oxide ore inodzoserwa neSulfutic acid, dzosera iyo mhangura mineral mune sulfuric mhinduro mhinduro inotakura mhangura sulfate solid solid solution. Iyo mhangura yakabva yabvisirwa kubva pamhangura sulfate Solution
