Cov khoom siv kho tshuab ntawm cov zaub mov xa mus rau ntau yam khoom uas cov zaub mov nthuav tawm thaum raug rau sab nraud. Lub zog ntawm cov ntxhia muaj ntau qhov sib txawv, tab sis cov khoom siv kho tshuab uas cuam tshuam rau kev sib tsoo ntawm cov ntxhia yog feem ntau hardness, toughness, cleavage thiab structural defects.
1, hardness ntawm minerals. Lub hardness ntawm ib tug ntxhia yog hais txog qhov xwm ntawm cov ntxhia tsis kam mus rau sab nraud mechanical quab yuam intrusion. Cov ntsiab lus tseem ceeb ntawm cov pob zeb hauv av - ions, atoms thiab molecules tau teem caij ib ntus hauv qhov chaw nrog cov kev cai geometric, thiab txhua lub sijhawm ua ib lub xov tooj ntawm tes, uas yog lub hauv paus ntawm siv lead ua. Plaub hom kev sib cog lus ntawm cov ntsiab lus: atomic, ionic, metallic thiab molecular bonds txiav txim siab qhov nyuaj ntawm cov pob zeb hauv av. Cov ntxhia pob zeb ua los ntawm kev sib txuas sib txawv muaj cov khoom sib txawv, thiab yog li ntawd kuj qhia txawv hardness. Minerals tsim los ntawm cov ntawv sib txawv ntawm cov ntawv cog lus qhia sib txawv ntxhia hardness.
2, toughness ntawm minerals. Thaum cov ntxhia siab dov, txiav, hammering, dabtsi yog khoov lossis rub thiab lwm yam sab nraud, nws kuj yog hu ua toughness ntawm cov ntxhia. Toughness, nrog rau brittleness, saj zawg zog, ductility, yooj thiab elasticity, yog ib tug neeg kho tshuab yam uas muaj feem xyuam rau lub crushing ntawm minerals.
3, mineral cleavage. Cleavage yog hais txog cov cuab yeej ntawm cov pob zeb tawg rau hauv lub dav hlau du nyob rau hauv ib qho kev taw qhia nyob rau hauv qhov kev txiav txim ntawm sab nraud rog. Lub dav hlau du no hu ua cleavage plane. Cleavage phenomenon yog ib qho tseem ceeb txhua yam uas cuam tshuam rau qhov tsis ua hauj lwm ntawm cov zaub mov. Cov ntxhia sib txawv tuaj yeem muaj qhov sib txawv ntawm qhov sib txawv, thiab cov qib ntawm cleavage nyob rau hauv tag nrho cov lus qhia ntawm tib cov ntxhia kuj tuaj yeem sib txawv. Cleavage yog ib qho tseem ceeb ntawm cov zaub mov, thiab ntau cov zaub mov muaj cov yam ntxwv no. Lub xub ntiag ntawm cleavage yuav txo tau lub zog ntawm cov pob zeb hauv av thiab ua rau cov ntxhia yooj yim crushed.
4. Cov qauv tsis xws luag ntawm cov ntxhia. Cov pob zeb ntxhia hauv cov xwm txheej, vim muaj qhov sib txawv ore-forming geological tej yam kev mob lossis kev paub dhau los, feem ntau ua rau cov khoom sib txawv ntawm tib cov ntxhia ua nyob rau hauv ntau qhov chaw. Qhov tsis xws luag hauv pob zeb thiab ore qauv yog ib qho tseem ceeb ntawm qhov sib txawv no. Qhov kev tsis zoo no hauv cov qauv ntxhia feem ntau ua rau cov pob zeb tawg yooj yim, yog li tus cwj pwm crushing yuav tshwm sim thawj zaug ntawm cov khoom tawg yooj yim.
Cov ore tsim nyob rau hauv cov xwm txheej, tshwj tsis yog rau ob peb ntawm cov ntxhia pob zeb, feem ntau ntawm cov ore nrog ntau cov ntxhia hauv cov ntxhia. Cov cuab yeej cuab tam ntawm ib qho ntxhia pob zeb yog qhov yooj yim. Cov khoom siv kho tshuab ntawm cov pob zeb uas muaj ntau yam minerals yog qhov kev ua tau zoo ntawm cov khoom ntxhia hauv cov khoom ntawm cov khoom. Cov cuab yeej cuab tam ntawm cov ore yog qhov nyuaj heev. Dhau li ntawm cov kev cuam tshuam uas tau hais los saum no, cov khoom siv kho tshuab ntawm cov ore kuj tseem cuam tshuam nrog cov txheej txheem ore-forming geological, mining blasting thiab tsheb thauj mus los, ore crushing theem thiab lwm yam.
