Gusobanukirwa no Gukoresha Pyrite (Iron Sulphide)

Iki gitabo cyuzuye kirasesengura imiterere, porogaramu, hamwe nibitekerezo byumutekano bikikije sulphide pyrite, bizwi kandi nka pyrite yicyuma cyangwa zahabu yumupfapfa. Twinjiye mubigize imiti, imikoreshereze yinganda, ingaruka zidukikije, nibishobora guteza ingaruka. Wige gutandukanya sulphide pyrite uhereye ku yandi mabuye y'agaciro kandi ukumva akamaro kayo mubice bitandukanye.

Pyrite (Iron Sulphide) ni iki?

Sulphide pyrite (FeS₂) ni minerval sulfide minerval ifite ibara ry'umuringa-umuhondo hamwe nicyuma. Izina ryayo rikomoka ku ijambo ry'Ikigereki pyr, risobanura umuriro, ryerekana ubushobozi bwaryo bwo gutanga ibishashi iyo bikubiswe. Uyu mutungo, hamwe nuburyo bugaragara, akenshi biganisha ku kwibeshya nka zahabu, bityo izina ryizina rya zahabu. Nyamara, imiterere yacyo ya cubic cyangwa pyritohedral kristaliste ituma habaho kumenyekana neza nabahanga mubumenyi bwa geologiya hamwe nabakunda amabuye y'agaciro. Amabuye y'agaciro aragaragara hose mubice byinshi bya geologiya, bikunze kuboneka mumabuye yaka, metamorphic, nubutayu.

Ibigize imiti nibyiza

Sulphide pyrite igizwe ahanini nicyuma na sulfure, hamwe nibintu bya trike rimwe na rimwe bihari. Ubukomezi bwayo ku gipimo cya Mohs ni 6-6.5, byerekana isano iri hagati yo gushushanya. Amabuye y'agaciro yerekana sisitemu ya cubic sisitemu itandukanye, akenshi yerekana kristu yakozwe neza hamwe nibiranga. Ubucucike bwayo bugera kuri 5 g / cm3, hejuru cyane ugereranije nandi mabuye y'agaciro. Imiti ihamye ya sulphide pyrite biratandukanye cyane bitewe nibidukikije. Oxidation hamwe no kurekura aside sulfurike nimpungenge zikomeye tuzabiganiraho nyuma mubuyobozi.

Inganda zikoreshwa mu nganda za Pyrite

Sulphide pyrite ifite akamaro gakomeye mu nganda. Amateka, yabaye isoko ya sulfuru yo gukora aside ya sulfurike, imiti ikomeye mubikorwa byinshi byinganda. Mugihe imikoreshereze yacyo muri ubu bushobozi yagabanutse bitewe no kubona amasoko meza ya sulferi asukuye, iracyabona gusaba muri:

1. Umusaruro wa Acide ya sulfure

Mugihe bitagaragaye cyane ubu, sulphide pyrite ikomeje kuba isoko ya sulfure yo kubyara aside sulfurike mu turere tumwe na tumwe. Ubu buryo ariko, bukubiyemo gutekereza cyane kubidukikije bitewe no kubyara dioxyde de sulfure, ihumanya ikirere. Uburyo bugezweho bushimangira tekiniki zisukuye kandi zangiza ibidukikije.

2. Ubucukuzi bw'amabuye y'agaciro na Metallurgie

Pyrite ikunze kuboneka hamwe nandi mabuye y'agaciro, kandi kuba ahari bishobora kugira ingaruka mubucukuzi bw'amabuye y'agaciro. Okiside yayo irashobora kugira ingaruka ku gucukura no gutunganya andi mabuye y'agaciro, bisaba gucunga neza no gutekereza ku mabwiriza y’ibidukikije. Ni ngombwa gukora isesengura ry’amabuye y'agaciro no gusuzuma ingaruka ku bidukikije mbere yo gutangira ibikorwa byose by'ubucukuzi.

Ingaruka ku bidukikije no gutekereza ku mutekano

Okiside ya sulphide pyrite irashobora gutuma habaho aside sulfurike, igira uruhare mu kuvoma amabuye ya acide (AMD), ikibazo gikomeye cyibidukikije. Iyi nzira irekura ibyuma biremereye mubidukikije, bigatera kwanduza amazi no kwangiza ibidukikije. Gusobanukirwa no kugabanya ingaruka za AMD ni ngombwa mu bikorwa byo gucukura amabuye y'agaciro no gutunganya amabuye y'agaciro. Uburyo bwo gucukura amabuye y'agaciro, nko gucunga neza imyanda, ni ngombwa mu gukumira cyangwa kugabanya ingaruka z’ibidukikije ziterwa na okiside ya pyrite.

Gutandukanya Pyrite na Zahabu

Amashusho asa hagati sulphide pyrite na zahabu akenshi biganisha ku kutamenya neza. Ariko, itandukaniro ryinshi ryingenzi rirahari. Ubusanzwe Pyrite yerekana kamere yoroheje kandi yububiko bwa kirisiti, mugihe zahabu ishobora kugaragara kandi ikerekana ibara ryumuhondo ryumuhondo ridafite ibara ryumuringa wa pyrite. Ikizamini cyoroshye cyoroshye, kinyunyuza imyunyu hejuru yisahani ya farashi, irashobora gutandukanya byombi. Pyrite itanga umukara wijimye wijimye-umukara, mugihe zahabu isize umurongo wumuhondo.

Umwanzuro

Sulphide pyrite, nubwo ifitanye isano na zahabu yumupfapfa, ifite akamaro kanini mubikorwa byinganda no mubutaka bwa geologiya. Gusobanukirwa imiterere, imikoreshereze, nibidukikije ni ngombwa mugucunga umutungo no kurengera ibidukikije. Ubundi bushakashatsi niterambere ryikoranabuhanga bikomeje kunonosora imyumvire no gukoresha iyi minerval itandukanye. Ukeneye ibisobanuro birambuye kubyerekeranye no gutunganya amabuye y'agaciro no gutekereza kubidukikije, nyamuneka ubaze umutungo wa leta n'inganda bireba.
