Cov yam ntxwv ntawm tooj liab minerals
kuv lub teb chaws cov khoom siv tooj liab ntxhia muaj cov yam ntxwv hauv qab no:
Copper ntxhia raw cov ntaub ntawv tsim nyog rau kev pab thiab smelting ntau lawm muaj nyob rau hauv ntau hom deposits. Ntawm lawv, hom deposits nrog ib qho tseem ceeb mining nqi: magmatic tooj liab-nickel sulfide deposits, porphyry tooj liab deposits, skarn-hom tooj liab thiab polymetallic deposits, hydrothermal leeg-hom tooj liab deposits, volcanic sedimentary loj sulfides tooj liab deposits, sedimentary txheej deposits, lwm.
Cov txheej txheem ore yog complex, nrog tsis sib npaug particle loj. Feem ntau ntawm cov ores yog unevenly disseminated. Tseem muaj ntau cov ntxhia sib xyaw ua ke thiab cov qauv nrog cov qauv zoo nkauj, cov txheej txheem nyuaj, thiab ntau cov ores uas nyuaj rau kev sib cais.
Cov ores muaj ntau yam tshuaj muaj pes tsawg leeg, muaj feem xyuam nrog ntau yam muaj txiaj ntsig thiab tsis zoo, thiab cov txheej txheem rau kev hnav khaub ncaws thiab smelting yog complex. Feem ntau ntawm cov chaw mining tsim yog cov khoom siv tooj liab, uas muaj feem xyuam nrog ntau yam muaj txiaj ntsig thiab tsis zoo. Los ntawm kev siv cov mining thiab kev siv dav, kev puas tsuaj tuaj yeem hloov mus rau qhov txiaj ntsig thiab pov tseg rau hauv cov khoom muaj nqis.
