Umuringa nicyuma gikomeye, kirwanya ruswa kandi nticyoroshye kwangirika.Ibikorwa bya chimique bikurikirana ni bike cyane, gusa birenze ibya feza, platine na zahabu, imikorere yayo rero irahagaze neza.Mu kirere, umuringa nawo uteza imbere umuringa wawo wa oxyde y'umuringa kugirango wirinde okiside no kwangirika.Mugihe ibikoresho byinshi byicyuma kuva mugihe kimwe byangiritse ndetse bikabyara oxyde nivu, umuringa uracyakora neza.Umuringa umara igihe kinini kuruta ibiti kandi birwanya ikirere kuruta amabuye.
Umuringa nawo ni ibikoresho bitangiza ibidukikije, kandi ubunini bwacyo buri gihe bugarukira kumutekano wibidukikije.Umuringa urashobora gukoreshwa neza nta myanda.Ndetse n'umuringa wongeye gukoreshwa ugumana imiterere yumuringa wambere.Umuringa uzwi kandi nka "icyuma cyumuntu" kubera imiterere karemano n'ibiranga abantu biranga ubukire, uburambe, ibirori n'ubushyuhe.
Umutako wumuringa wakoreshejwe cyane mubwubatsi nibyiza byihariye.Ingazi z'umuringa nizo zijya guhitamo inyubako zo mu rwego rwo hejuru, cyane cyane amazi n'ubushyuhe.
Umuringa uramba kandi urashobora gukoreshwa.Umuringa wagiye uhinduka patina nziza cyane ifite ibara ryiza, irwanya kwangirika kwikirere, hamwe nikirere gisanzwe.Irashobora kandi gutunganyirizwa mumabara atandukanye ashimishije hamwe nuburabyo.
Nkibikoresho bishushanya, umuringa ufite urukurikirane rwimiterere yuburanga nkimbaraga nyinshi, isura nziza, kuramba gukomeye, kurwanya umuriro, kubungabunga igihe, kubungabunga byoroshye, gushiraho byoroshye, no kongera gukoreshwa.Hano haribisabwa byinshi kandi bitari mu nyubako za kera gusa, ahubwo no mububiko rusange bugezweho, inyubako zubucuruzi ninyubako zo guturamo.Mu nganda zubaka, Lvliang Copper Industry iha abantu kwishimira ubwiza nuburyo bwihariye, ubwiza nuburyo bwiza.Mu mateka ya muntu, umuringa wagize ingaruka zikomeye kandi zigera kure ku iterambere ryamateka.Nibicuruzwa byibihe kandi byihutishije cyane umuvuduko witerambere ryamateka.
