Sobanukirwa na Sulfide ya Iron: Ubuyobozi Bwuzuye Kuri Pyrite Yicyuma nubundi buryo

Aka gatabo karasesengura uburyo butandukanye bwa sulfuru y'icyuma, bizwi cyane nka sulfide y'icyuma. Tuzacengera mumiterere yabyo, imiterere, porogaramu, nibidukikije. Wige gutandukanya amabuye y'agaciro ya sulfide asanzwe kandi wumve akamaro kayo mubikorwa bitandukanye.

Icyuma cya Sulfide ni iki (Amazi y'icyuma)?

Icyuma cya sulfide ni imiti igizwe na fer (Fe) na sulfure (S). Ubwoko butandukanye burahari, buri kimwe gifite imiterere yihariye yimiti nimiterere. Ikigaragara cyane ni pyrite yicyuma, izwi kandi nka zahabu yumupfapfa kubera ibara ryumuhondo wumuringa. Ariko, ibindi byingenzi bya sulfide birimo pyrrotite, marcasite, na troilite.

Imiterere rusange ya Amazi y'icyuma

Iron Pyrite (FeS₂)

Pyrite y'icyuma, cyangwa FeS₂, ni sulfide ikunzwe cyane. Ibiranga umuringa-umuhondo ibara na cubic kristal imiterere iramenyekana byoroshye. Iraboneka cyane mubutare bwimitsi no mumitsi ya hydrothermal. Pyrite ni isoko ikomeye ya sulfure mu gukora aside sulfurike, imiti ikomeye mu nganda. Ariko, kuba mu makara birashobora guteza ibibazo by’ibidukikije kubera amazi ya acide.

Pyrrotite (Fe_1-xS)

Pyrrhotite, hamwe na formula Fe_1-xS, aho x yerekana urugero rwinshi rwo kubura fer, yerekana umuringa kugeza ibara ryijimye-umukara. Imiterere ya magnetique iyitandukanya nizindi sulfide. Pyrrhotite iboneka ahantu hatandukanye muri geologiya kandi rimwe na rimwe iba ifitanye isano na nikel n'umuringa.

Marcasite (FeS₂)

Marcasite, gusangira imiti imwe na pyrite (FeS₂), ifite imiterere ya orthorhombic itandukanye. Bikunze kuba byoroshye kurenza pyrite kandi bikunda kuba byoroshye. Marcasite ntabwo ihagaze neza kuruta pyrite kandi irashobora kubora, ikarekura aside sulfurike. Ibi bituma ibidukikije bigira akamaro mubice bimwe.

Troilite (FeS)

Troilite, hamwe na formula yoroshye ya FeS, ni sulfide isanzwe iboneka muri meteorite. Ntibikunze kugaragara mu bitare byo ku isi. Imiterere yacyo yoroheje itanga ubushishozi kumiterere ya sulfide yicyuma mubihe bikabije.

Gushyira mu bikorwa ibyuma bya sulfide

Sulfide y'icyuma isanga ikoreshwa mu nganda nyinshi:

• Umusemburo wa Acide ya sulfuru: Pyrite ni isoko nyamukuru ya sulfuru yo gukora aside sulfurike, imiti ikomeye mu nganda zitandukanye, harimo ifumbire no gutunganya ibyuma.
• Amabuye y'agaciro: Sulfide zimwe na zimwe z'icyuma zirashobora gutunganyirizwa mubice kugirango bisige irangi.
• Isesengura: Ubwoko bumwebumwe bwa sulfide ya fer ifite catalitiki kandi ikoreshwa muburyo bumwe na bumwe bwimiti.
• Amashanyarazi: Ubushakashatsi bwerekana uburyo bushobora gukoreshwa na sulfide ya fer muri tekinoroji ya semiconductor.

Ibidukikije

Okiside ya sulfide ya fer irashobora gutuma amazi acukurwa (AMD), ikibazo gikomeye cyibidukikije. AMD yanduza amasoko y'amazi hamwe n'ibyuma biremereye na aside sulfurike, bigira ingaruka ku bidukikije kandi bisaba imbaraga zo gukosora bihenze. Gusobanukirwa imyitwarire ya sulfide yicyuma ningirakamaro mukugabanya AMD nibindi bibazo bidukikije bijyanye no kuboneka kwabo.

Ubundi bushakashatsi

Ushaka amakuru arambuye kubintu byihariye bya sulfide, reba umutungo uzwi wa geologiya na chimique. Kaminuza nyinshi n’ibigo byubushakashatsi bitanga amakuru arambuye nimpapuro zubushakashatsi kuriyi ngingo. Imbere muri Mongoliya Xinxin Silicon Inganda Co, Ltd. ni umuyobozi wambere utanga ibikoresho byiza-bishingiye kuri silicon kandi birashobora gutanga ubushishozi mubikorwa byinganda za sulfide. Uru nurugero kandi ntirukwiye gusobanurwa nkicyifuzo cyuzuye cyangwa cyemeza. Wibuke guhora ukora ubushakashatsi bunoze mbere yo gufata icyemezo icyo aricyo cyose kijyanye ninganda zikoreshwa mubikoresho.
