Nigute agaciro k'umuringa kubitsa?

Nigute agaciro k'umuringa kubitsa?

Hariho ibintu byinshi ugomba gusuzuma mugihe ugena agaciro k'umuringa kubitsa. Mubindi bintu, ibigo bigomba gusuzuma amanota, gutunganya ibiciro, bigereranya umutungo wumuringa no korohereza gucukura umuringa. Hasi ni incamake yibintu byinshi ugomba gusuzuma mugihe ugena agaciro k'umuringa kubitsa.

Ni ubuhe bwoko bw'umuringa buhari?

PORPHYRY kubitsa ni amanota make ariko ni isoko yingenzi yumuringa kuko ishobora gucukurwa ku rugero runini ku giciro gito. Mubisanzwe birimo 0.4% kuri 1% yumuringa nubundi buryo bwabandi byuma nka molybdenum, ifeza na zahabu. Porogaramu ya porphyry yo kubitsa ni nini nini kandi ikurwa mu bucukuzi bwamabuye.

Umuringa wanditseho umuringa ni ubwoko bwa kabiri bwingenzi bwabitswe, ibaruramari hafi kimwe cya kane cyisi yavumbuwe kwisi.

Ubundi bwoko bwibitsa umuringa buboneka kwisi harimo:

Ikirunga kinini cya sulfide (VMS) kubitsa ni isoko yumuringa wakozwe mubintu bya hydrothermal mubidukikije bya mu nyanja.

Icyuma cya oxide-copper-zahabu (iocg) kubitsa ni byinshi-byibanze byumuringa, zahabu na Uranium.

Umuringa wa Skarn, mu magambo yose, yashyizweho binyuze mu guhindura imyuka mibi n'imiterere ibaho iyo Lithologi ebyiri zitandukanye zizana.

Ni ubuhe buryo bugereranywa bw'umuringa?

Icyiciro nikintu cyingenzi mugihe cyo kubitsa amabuye y'agaciro kandi ni igipimo cyiza cyo kwibanda kubyuma. Imisanzu myinshi yumuringa irimo igice gito gusa cyubwicanyi bwakingiwe mu mabuye y'agaciro. Ibisigaye mu kibuye ni urutare rudashaka.

Amasosiyete yubushakashatsi atwara gahunda yo gucukura kugirango akuremo ingero zitwa cores. Core noneho yasesenguwe na chimique kugirango hamenyekane "icyiciro" cyo kubitsa.

Urwego rwo kubitsa muri Copper ubusanzwe rugaragazwa nkibiro byijana ryurutare rwose. Kurugero, kilo 1000 yumuringa urimo ibiro 300 byibyuma byumuringa hamwe nicyiciro cya 30%. Iyo kwibanda ku icyuma biri hasi cyane, birashobora gusobanurwa mubijyanye n'ibice kuri miliyoni. Nyamara, urwego nimahugurwa rusange ku masosiyete y'umuringa, no gushakisha ibigereranyo binyuze mu gucukura no gusuzuma.

Impuzandengo y'umuringa y'umuringa mu kinyejana cya 21 iri munsi ya 0,6%, hamwe na minerval y'amabuye y'agaciro mu gitabo cyose kitari munsi ya 2%.

Abashoramari bagomba kureba amanota yicyiciro hamwe nijisho rinegura. Iyo isosiyete yubushakashatsi itanga amanota, abashoramari bagomba kumenya neza kugereranya n'imbaraga zose z'inzoga zikoreshwa mu kumenya amanota. Agaciro k'urwego rwo hejuru ku burebure bwo hasi ni munsi cyane kuruta agaciro k'icyiciro cya mediocre gihuye neza.

Bitwara angahe kuri njye umuringa?

Ibicumi binini kandi byunguka cyane ni ibicumi bifunguye, nubwo ibirombe by'umuringa bitari bisanzwe. Ikintu cyingenzi muburyo bwa sano ni umutungo ugereranije hejuru.

Amasosiyete acukura amabuye y'agaciro ashishikajwe cyane cyane na kure cyane, akaba ari ingano y'urutare rudafite agaciro n'ubutaka hejuru y'umuringa. Ibi bikoresho bigomba gukurwaho kugirango ubone ibikoresho. Escondida, yavuzwe haruguru, afite ibikoresho bitwikiriye hejuru cyane cyane, ariko kubitsa biracyafite agaciro k'ubukungu bitewe n'ubutunzi bwinshi.

Ni ubuhe bwoko bw'amabuye y'umuringa?

Hariho ubwoko bubiri butandukanye bwabitswe: sulfide ores na oxide amabuye ya oxide. Kugeza ubu, isoko rusange yumuringa ni sulfide chalcopyrite, zingana na 50% yumusaruro wumuringa. Amabuye ya sulfide atunganijwe binyuze muri flatrotion ya farth kugirango abone umuringa yibanda. Umuringa urimo Chalcopyrite urashobora kubyara kwibanda kubamo 20% kugeza 30% umuringa.

Ikindi gihe cya chalcocite yibanze ni amanota yo hejuru, kandi kubera ko Chalcocite ikubiyemo nta cyuma, ibirimo umuringa mubice byibanda kuri 37% kugeza kuri 40%. Chalcocite yacukuwe mu binyejana byinshi kandi ni imwe mu mabuye y'umuringa yunguka cyane. Impamvu yibi ni ibirimo birindari yumuringa, kandi umuringa urimo utandukanijwe byoroshye na sulfure.

Ariko, ntabwo arinjye ari umuringa ukomeye muri iki gihe. Umuringa ored ore uvanyweho aside sulfuric, irekura amabuye y'agaciro y'umuringa mu gisubizo cya sulfuric gitwara igisubizo cy'umuringa. Umuringa uhita wambuwe igisubizo cy'umuringa (cyitwa igisubizo gikungahaye ku gitambo cyiza) binyuze mu gukuramo ibintu no gukuramo ibintu na electrolytic neza, bikaba bike mu bukungu kuruta frotition ya farration.
