Sau, a ntxhia los yog aggregate ntawm cov ntxhia los ntawm qhov uas muaj txiaj ntsig zoo, tshwj xeeb yog a hlau , yuav tau profitably mined los yog rho tawm yog ib tug ore. Hlau -Ib qho hlau ntawm ob lossis ntau dua hlau. Yog li ntawd, Pob zeb muaj cov ntxhia , uas nyob rau hauv loj concentration yog hu ua ore thiab cov no yog mined rau hlau !

Ua kom pom qhov no, puas yog hlau suav tias yog cov ntxhia?

Hlau yog inorganic thiab feem ntau muaj crystalline lug thiab yog khoom. Txhua yam koj xav tau yog rau qhov ntawd hlau tshwm sim lawm ntawm nws haiv neeg daim ntawv rau nws ua ib tug ntxhia . Txawm li cas los xij, muaj cov xwm txheej uas muaj hlau, ib txwm muaj hlau tau pom, feem ntau nyob rau hauv meteorites, yog li Hlau yog ib qho hlau. ntxhia.

Ib yam li ntawd, pob zeb twg muaj hlau nyob hauv nws? Lub pob zeb lossis pob zeb uas tuav cov hlau yog hu ua ib ore . Ib ore yog rhuab nrog tshuaj kom txog thaum nws melts thiab cov ntshiab hlau cais tawm raws li ib tug kua. Cov kua ces txias thiab hardens. Ob peb cov hlau, xws li kub, nyiaj, thiab tooj liab tuaj yeem pom hauv daim ntawv ntshiab raws li cov khoom hlau.

Ib sab saum toj no, lub pob zeb txawv li cas ntawm cov ntxhia?

[edit] A ntxhia yog ib tug tshwm sim, inorganic khoom nrog ib tug meej tshuaj muaj pes tsawg leeg thiab ib tug crystalline qauv tsim los ntawm cov txheej txheem geological. A pob zeb yog kev sib sau ua ke ntawm ib lossis ntau dua cov ntxhia hos a pob zeb kuj tseem muaj cov organic seem thiab mineraloids.

Yog ntsev yog ib qho ntxhia?

Ntsev yog a ntxhia muaj feem ntau ntawm sodium chloride (NaCl), cov tshuaj sib xyaw ua ke ntawm cov ntsev loj dua; ntsev nyob rau hauv nws daim ntawv ntuj raws li ib tug crystalline ntxhia yog lub npe hu ua pob zeb ntsev los yog halite. Ntsev yog tam sim no nyob rau hauv ntau ntau nyob rau hauv seawater, qhov twg nws yog lub ntsiab ntxhia lub hauv paus.
