Sebopeho sa Lik'hemik'hale le Thepa

Iron pyrite (FeS?) ke minerale ea tšepe ea sulfide e nang le sebopeho se ikhethileng sa cubic crystal. Foromo ea eona ea lik'hemik'hale e bontša karolelano ea 1: 2 ea tšepe (II) ho sebabole. Sebopeho sena se hlahisa likarolo tse 'maloa tsa bohlokoa:

Lintho Tsa 'Mele

Mmala: Hangata e mosehla oa koporo, hangata o na le mebala e khanyang. Ho thatafala: Ho batla ho le thata (6-6.5 sekaleng sa boima ba Mohs). Matla a Khoheli: Hoo e ka bang 5.0 g/cm3. Streak: Botala bo botala kapa bo sootho-botšo. Cleavage: Cubic, empa hangata e sa phethahala. Ho robeha: Conchoidal.

Lintho tsa Lik'hemik'hale

Iron pyrite e batla e tsitsitse tlas'a maemo a tloaelehileng, empa e ka itšoara ka oksijene le metsi ho etsa sulfuric acid, mokhoa o tsejoang e le acid mine drainage. Ts'ebetso ena e bohlokoa maemong a tikoloho le ts'ebetsong ea merafo. Karabelo ena e matla haholo 'me e ka hlahisa mocheso o moholo.

Iron pyrite Mefuta e fapaneng maemong a fapaneng a jeoloji, haholoholo ka lits'ebetso tsa hydrothermal, deposition ea sedimentary, le phetoho ea metamorphic. Ke minerale e tlwaelehileng e fumanwang majweng a sedimentary, majwe a sedimentary, le majwe a metamorphic lefatsheng ka bophara. Hangata li-deposit tse bohlokoa li amahanngoa le seams tsa mashala, 'me hangata li fumanoa methapong ea hydrothermal.

Tšebeliso ea Iron Pyrite

Ho latela nalane, tšepe pyrite e ne e fosoa ka khauta (khauta ea leoatla), empa e na le lisebelisoa tse 'maloa tsa bohlokoa:

Lisebelisoa tsa indasteri

Tlhahiso ea Sebabole: Iron pyrite ke mohloli oa bohlokoa oa sebabole bakeng sa indasteri ea lik'hemik'hale, e sebelisoang tlhahisong ea sulfuric acid, e nang le lits'ebetso tse fapaneng. Ts'ebetso ea tšepe pyrite ho hlahisa sebabole ho kenyelletsa ho besa (ho futhumatsa ka pel'a moea). Tlhahiso ea Iron: Le hoja e sa tloaeleha, tšepe pyrite e ka sebelisoa e le mohloli oa tšepe, le hoja litšepe tse ling ka kakaretso li sebetsa hantle haholoanyane.

Lisebelisoa tse ling

Li-pigments: E siiloe hantle tšepe pyrite e 'nile ea sebelisoa historing e le pigment. Merero ea Mokhabiso: Ponahalo ea eona e khahlehang e etsa hore e tšoanelehe ho sebelisoa ho roala mabenyane, le hoja boima ba eona bo batlang bo le tlaase bo bolela hore e loketse ka ho fetisisa bakeng sa lintho tse sa aparoang haholo.

Tšusumetso ea Tikoloho

Oxidation ea tšepe pyrite, haholo-holo mesebetsing ea merafo, e ka lebisa mathateng a bohlokoa a tikoloho. Acid mine drainage (AMD) e bakoang ke oxidation ena e silafatsa litsela tsa metsi, e senya bophelo ba metsing le tikoloho. Maano a sebetsang a tsamaiso ea likhoerekhoere tsa morafo a bohlokoa ho fokotsa tšusumetso ea tikoloho ea tšepe pyrite oxidation.
