Iron Sulfide Pyrite: Tataiso e FeletsengIron sulfide pyrite, eo hape e tsejoang e le khauta ea fool, ke liminerale tse tloaelehileng tse nang le nalane e khahlang le lits'ebetso tse fapaneng. Tataiso ena e shebisisa litšobotsi tsa eona, litšebeliso le bohlokoa ba tikoloho.

Iron Sulfide Pyrite: Tataiso e Pharalletseng

Iron sulfide pyrite (FeS₂), eo hangata e nkoang ka phoso e le khauta ka lebaka la 'mala oa eona o mosehla oa koporo, ke liminerale tse fumanehang hohle tse fumanehang libakeng tse fapaneng tsa jeoloji. Tataiso ena e fana ka kakaretso ea kakaretso ea tšepe sulfide pyrite, e koahelang thepa ea eona, sebopeho, tšebeliso, le phello ea tikoloho. Kutloisiso tšepe sulfide pyrite e bohlokoa ho pholletsa le mafapha a mangata, ho tloha merafong le metallurgy ho ea ho tokiso ea tikoloho esita le maemo a histori.

Lintho tsa 'Mele le Lik'hemik'hale tsa Pyrite

Ponahalo le Sebopeho sa Crystal

Iron sulfide pyrite hangata e hlaha joalo ka likristale tse bosehla bo bosehla tse nang le tšepe e phatsimang. Sebopeho sa eona sa kristale se na le li-cubic, hangata se etsa li-cubes tse fapaneng kapa li-pyritohedron. Leha ho le joalo, e ka boela ea hlaha ka mefuta e meholo, ea granular kapa e hasaneng. Bothata ba tšepe sulfide pyrite ke 6-6.5 sekaleng sa Mohs, ho etsa hore ho be thata haholo.

Sebopeho sa Lik'hemik'hale le Lits'ebetso

Foromo ea lik'hemik'hale ea Pyrite, FeS₂, e bontša sebopeho sa eona: tšepe le sebabole. E batla e tsitsitse tlas'a maemo a tloaelehileng, empa e khona ho ntša oxidize ha e pepesehetse moea le metsi, e hlahisa sulfuric acid le iron hydroxides. Ts'ebetso ena ea oxidation, e tsejoang e le acid mine drainage (AMD), e na le litlamorao tse kholo tsa tikoloho, tse tla tšohloa hamorao. Reactivity ena ea lik'hemik'hale ke ntlha ea bohlokoa lits'ebetsong tsa eona tsa indasteri le mathata a tikoloho.

Ho thehoa le ho etsahala ha Pyrite

Iron sulfide pyrite mefuta e fapaneng ea maemo a jeoloji, hangata a amahanngoa le mafika a sedimentary, methapo ea hydrothermal, le majoe a metamorphic. E ka theha ka lits'ebetso tsa biogenic le abiogenic. Bongata ba tšepe le sebabole tikolohong bo phetha karolo ea bohlokoa ho ajoeng ha eona hohle. Libaka tse ngata tse ruileng ka tšepe sulfide pyrite li-deposit le tsona ke libaka tsa ts'ebetso ea bohlokoa ea indasteri.

Lisebelisoa tsa Indasteri tsa Pyrite

Tlhahiso ea Sulfur Acid

Ho latela nalane, tšepe sulfide pyrite e bile mohloli oa bohlokoa oa sebabole bakeng sa tlhahiso ea sulfuric acid. Le ha mehloli e meng e se e atile haholo, pyrite e ntse e sebetsa libakeng tse ling le lits'ebetsong tsa indasteri. Ho chesoa ha pyrite ho hlahisa sulfur dioxide (SO₂), ebe joale e fetoloa sulfuric acid. Ts'ebetso ena, le hoja e le bohlokoa, e boetse e tlatsetsa tšilafalong ea moea haeba e sa laoloe ka nepo.

Lisebelisoa tse ling

Ntle le tlhahiso ea sulfuric acid, tšepe sulfide pyrite e fumana lintho tse sebelisoang tlhahisong ea tšepe le tšepe, e le 'mala oa lipente le ha ho etsoa lik'hemik'hale tse itseng. Thepa ea eona e ikhethang e etsa hore e be mohloli oa bohlokoa maemong a fapaneng a indasteri.

Tšusumetso ea Tikoloho ea Pyrite

Phallo ea Asiti ea Merafo (AMD)

Oxidation ea tšepe sulfide pyrite ke sesosa se seholo sa acid mine drainage (AMD), bothata bo boholo ba tikoloho. AMD e silafatsa mehloli ea metsi ka tšepe e boima le sulfuric acid, e senya bophelo ba metsing le tikoloho. Maano a phokotso a bohlokoa ho fokotsa phello ea tikoloho ea pyrite oxidation. Tsamaiso e nepahetseng ea mehatla ea merafo le tšebeliso ea mekhoa ea tokiso ke mehato ea bohlokoa ho fokotsa AMD.

Lethathamo: Ho bapisa Pyrite le Li-sulfide tse ling tsa Iron

Lipatlisiso tse ling mabapi le thepa le lits'ebetso tse ikhethileng tsa tšepe sulfide pyrite e ka etsoa ka likoranta tse tsebahalang tsa saense le pokello ea boitsebiso ba jeoloji. Hopola, kamehla tšoara tšepe sulfide pyrite ka hloko ka baka la bokgoni ba yona ba ho ntsha oxidation le ho ntsha dintho tse kotsi.
