Kev paub dav dav txog ore qib
Qib ntawm ore yog hais txog cov ntsiab lus ntawm cov khoom tseem ceeb hauv cov ore.Feem ntau qhia nyob rau hauv huab hwm coj feem pua ​​(%).Vim muaj ntau hom minerals, cov txheej txheem ntawm kev qhia ore qib kuj txawv.Feem ntau cov hlau ore, xws li hlau, tooj liab, txhuas, zinc thiab lwm yam ores, yog qhia los ntawm qhov loj feem pua ​​ntawm cov ntsiab lus hlau;qib ntawm qee cov hlau ore yog qhia los ntawm qhov loj feem pua ​​​​ntawm lawv cov oxides, xws li WO3, V2O5, thiab lwm yam .;Qib ntawm cov khoom siv tsis yog hlau feem ntau yog qhia los ntawm qhov loj feem pua ​​​​ntawm cov khoom siv tseem ceeb lossis cov khoom sib txuas, xws li mica, asbestos, potash, alunite, thiab lwm yam.;Qib ntawm cov hlau muaj txiaj ntsig (xws li kub, platinum) ores feem ntau qhia hauv g / t; Qib ntawm pob zeb diamond ore yog qhia hauv mt / t (los yog carat / ton, sau ua ct / t);Qib ntawm placer ore feem ntau qhia hauv grams ib cubic centimeter lossis kilogram ib cubic meter.
Daim ntawv thov tus nqi ntawm ore yog ze ze rau nws qib.Ore tuaj yeem muab faib ua cov nplua nuj ore thiab cov ore tsis zoo raws li qib.Piv txwv li, yog cov hlau ore muaj qib siab tshaj 50%, nws yog hu ua cov nplua nuj ore, thiab yog tias qib 30%, nws hu ua cov ore tsis zoo.Raws li qee qhov kev lag luam thiab kev lag luam, qib kev lag luam ntawm ore tsim nyog mining feem ntau tau teev tseg, uas yog, qib qis tshaj plaws.Nws cov kev cai muaj feem xyuam nrog qhov loj ntawm qhov tso nyiaj, hom ore, kev siv dav dav, smelting thiab processing technology, thiab lwm yam. Piv txwv li, tooj liab ore tuaj yeem mined yog tias nws ncav cuag 5% lossis tsawg dua, thiab cov leeg kub nce mus txog 1 txog 5 grams / ton.
Cov qib kev lag luam yog hais txog cov khoom siv uas muaj txiaj ntsig zoo (tsawg kawg tuaj yeem lav qhov them rov qab ntawm ntau yam nqi xws li mining, tsheb thauj mus los, kev ua haujlwm thiab kev siv) hauv ib qho kev thaiv ntawm ib qho ore tsim reserves hauv ib qhov project (xws li drilling lossis trenching. ).Cov ntsiab lus nruab nrab qis tshaj ntawm cov khoom siv.Nws yog siv los txiav txim siab txog qib kev lag luam rov qab los yog kev lag luam sib npaug, uas yog, qib thaum cov nyiaj tau los ntawm cov mined ore sib npaug rau tag nrho cov nqi nkag thiab cov txiaj ntsig tsuas yog xoom.Cov qib muaj kev hloov pauv tas li nrog kev txhim kho ntawm kev lag luam thiab kev ua haujlwm thiab qib ntawm kev thov.Piv txwv li, los ntawm lub xyoo pua 19th mus rau tam sim no (2011), qib kev lag luam ntawm tooj liab mines tau nqis los ntawm 10% mus rau 0.3%, thiab txawm tias qib kev lag luam ntawm qee qhov loj qhib-qhov tooj liab deposits tuaj yeem poob mus rau 0. 2%.Tsis tas li ntawd, cov qib kev lag luam muaj cov qauv sib txawv rau ntau hom mineral deposits.
