Kev paub dav dav txog ore qib

Kev paub dav dav txog ore qib
Cov ແ grade່ ISE yog hais txog cov ntsiab lus ntawm cov khoom siv muaj txiaj ntsig hauv cov ore. Feem ntau qhia tawm hauv cov feem pua ​​(%). Vim muaj ntau hom ntawm cov zaub mov, cov hau kev ntawm cov qib ore kuj sib txawv. Feem ntau cov hlau, xws li hlau, tooj liab, ua, duas, yog qhia los ntawm qhov feem pua ​​ntawm cov khoom siv hlau; Cov qib ntawm qee cov hlau hluav taws xob yog qhia los ntawm cov feem pua ​​ntawm lawv cov oxides, xws li WO3, V2O5, thiab lwm yam; Cov qib ntawm feem ntau tsis yog xim hlau cov ntaub ntawv raw yog qhia los ntawm cov zaub mov muaj txiaj ntsig lossis cov lus sib txuas, xws li mica, asbestos, alunite, thiab lwm yam; Cov qib ntawm cov khoom siv muaj txiaj ntsig (xws li kub, platinum) ores feem ntau qhia hauv g / t; Cov qib ntawm placer ore yog feem ntau qhia nyob rau hauv grams ib cubic centimeter lossis kilogram ib lub cubic ib lub cubic.
Daim ntawv thov tus nqi ntawm ore yog ze ze rau nws qib. Ore tuaj yeem faib ua cov nplua nuj ee thiab pluag ore raws qib. Piv txwv li, yog tias ORE ORE muaj qib ntau dua 50%, yog tias cov qib yog li 30%, nws yog hu ua ib tug neeg pluag ore. Nyob rau hauv qee qhov kev siv thiab kev lag luam, qib kev lag luam ntawm ore tsim nyog mining feem ntau yog teev, yog, qhov tsawg kawg nkaus qib kev lag luam. Nws cov kev cai yog ze rau qhov loj me, ore siv, tooj liab, tooj liab, thiab tsawg dua, thiab cov leeg ntshav nce mus txog 1 txog 5 grams / tuj.
Muaj qib yog hais txog cov ntaub ntawv muaj txiaj ntsig uas muaj cov txiaj ntsig kev lag luam (tuaj yeem lav cov nyiaj them rov qab los ntawm ib qho ore tsim kev khaws cia hauv ib qho kev lim dej (xws li drilling lossis trenching ). Cov ntsiab lus qis tshaj plaws ntawm cov khoom sib xyaw. Nws yog siv los txiav txim siab qhov kev lag luam zoo los yog kev lag luam muaj txiaj ntsig, uas yog, cov nqi nyiaj tau los sib npaug thiab cov nyiaj tsuas yog xoom. Muaj qib muaj kev hloov pauv tas mus li nrog kev txhim kho kev lag luam thiab cov txheej txheem kev ua haujlwm thiab kev xav tau. Piv txwv li, txij li xyoo 19th mus rau tam sim no (2011), qib kev lag luam ntawm 10% rau 0.3%, thiab txawm tias qib tooj liab kev lag luam tuaj yeem poob rau 0. 2%. Ib qho ntxiv, cov qib muaj muaj cov qauv sib txawv rau ntau hom ntxhia tso tawm.
