Muaj ob qhov kev faib tawm tseem ceeb ntawm cov zaub mov. Cov zaub mov tseem ceeb yog cov zaub mov uas koj lub cev xav tau nyob rau hauv qhov loj (lossis loj) ntau, thiab cov pob zeb hauv av yog cov zaub mov uas koj lub cev xav tau hauv qhov me me (lossis kab) ntau. Cov zaub mov tseem ceeb muaj xws li sodium, potassium, chloride, calcium phosphorus, magnesium thiab leej faj.

Yog li ntawd, dab tsi yog cov ntxhia kev faib tawm?

Lub Dana system faib cov ntxhia mus rau yim chav kawm yooj yim. Cov chav kawm yog: haiv neeg, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, thiab mineraloids. Daim duab hauv qab no muaj cov duab thiab cov lus piav qhia ntawm txhua chav kawm nrog qhov txuas mus rau cov piv txwv thiab cov ntsiab lus ntxiv.

Tsis tas li ntawd, dab tsi yog qhov sib txawv ntawm cov zaub mov thiab lawv siv? 40 hom minerals & lawv siv

  • Antimony. Antimony yog cov hlau uas siv nrog rau cov hlau los tsim cov roj teeb rau khaws cov phiaj xwm hluav taws xob.
  • Asbestos. Asbestos muaj lub koob npe nrov tsis txaus ntseeg ua rau mob qog noj ntshav hauv cov neeg ua haujlwm nyob ib puag ncig nws.
  • Barium.
  • Columbite-tantalite.
  • Tooj.
  • Feldspar.
  • Gypsum.
  • Halite.

Ib yam li ntawd, nws yog nug, dab tsi yog mineral cais nws nrog piv txwv?

cov ntxhia ua tau cais raws li lawv cov tshuaj muaj pes tsawg leeg. Raws li cov tswv yim no, lawv tau muab faib ua cov chav kawm raws li lawv qhov tseem ceeb anion lossis anionic pawg ( e.g ., halides, oxides, thiab sulfides). Cov ntxhia yog homogeneous ib txwm tshwm sim yam khoom uas muaj cov qauv tsim sab hauv.

Koj tuaj yeem txheeb xyuas cov ntxhia li cas?

Zaj Lus Qhia

  1. Koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov tsos thiab lwm yam khoom.
  2. Cov xim thiab luster piav txog cov tsos ntawm cov ntxhia, thiab streak piav txog cov xim ntawm cov hmoov ntxhia.
  3. Txhua pob zeb muaj ib tug yam ntxwv ceev.
  4. Mohs Hardness Scale yog siv los sib piv cov hardness ntawm cov zaub mov.
