Lus Taw Qhia Rau Pyrite Raw Materials

Pyrite raw cov ntaub ntawv yog ib tug complex sulfide ntxhia, lub ntsiab feem ntawm uas yog FeS2. Nws yog lub teeb tooj liab-xim, feem ntau nrog cov xim daj-xim av ntawm qhov chaw, muaj cov xim hlau nplaum, thiab hardness ntawm 6-6.5. Nws yog ib hom hlau ntxhia hauv cov xwm txheej thiab feem ntau nthuav tawm sulfide hauv lub ntiaj teb crust. [1-2] [7]
Pyrite raw cov ntaub ntawv yog tsim los ntawm ntau yam txheej txheem geological thiab tuaj yeem pom nyob rau hauv ntau yam pob zeb thiab ores (xws li coal seams). Lawv muaj cov txiaj ntsig zoo nkauj thiab tuaj yeem siv los ua cov pob zeb pheej yig (feem ntau hu ua "fool's gold"), thiab siv hauv kev lag luam los rho cov sulfur thiab ua sulfuric acid.
