Pyrite tuaj yeem pom nyob rau hauv cov av thiab sediments thoob plaws ntiaj teb li myriads ntawm microscopic crystals. Cov pyrite no yog tsim los ntawm kab mob uas tshem tawm cov pa oxygen los ntawm sulfate hauv dej, tsim cov sulfide uas cuam tshuam nrog hlau los ua pyrite. Ntau tshaj 90 feem pua ntawm cov pyrite hauv ntiaj teb yog tsim los ntawm cov txheej txheem microbiological.
Pyrite mined nyob qhov twg thiab ua li cas?
Pyrite yog qhov ntau tshaj plaws thiab ntau sulfide nyob hauv lub ntiaj teb thiab van muaj nyob rau hauv kaum tawm txhiab lub zos nrog loj thiab / lossis zoo siv lead ua yog tsim los ntawm Ltalis ntawm Elba thiab ntawm Piedmont, hauv Spain, Kazakhstan, hauv Tebchaws Meskas los ntawm Colorado, Illinois, Arizona, Pennsylvania, Vermont, Montana, Washington, …
Dab tsi ua rau pyrite tsim?
Cov txheej txheem ntawm pyrite tsim hauv sediments tshwm sim los ntawm kev ua ntawm cov kab mob, uas txo cov sulphate ions (solved hauv dej pore) rau sulphide. Yog tias muaj hlau tam sim no, hlau sulfide crystals pib loj tuaj.
Puas pom pyrite hauv mines?
Pyrite yog ntau nyob rau hauv thee deposits, tab sis hlawv cov thee uas muaj pyrite tso tawm cov sulfur, uas ua ke nrog oxygen los ua sulfur dioxide, huab cua paug. Kev cuam tshuam ntawm pyrite rau huab cua thaum lub sijhawm mining kuj tseem tuaj yeem ua rau cov kua qaub mine.
Puas pyrite tsim ib txwm muaj?
Pyrite yog cov ntxhia zoo nkauj uas naturally forms into cubic crystal structures … Tsis tas li ntawd, nws ua rau pyrite thiab cov khoom lag luam tseem ceeb rau ob qho tib si hlau thiab sulfur.
