Zomera zimabzalidwa munjira ya beficiation.Chifukwa cha kalasi yotsika ya ore, kuchuluka kwa michira kumapangidwa pothandizira, zomwe zimawerengera pafupifupi 90% ya miyala yaiwisi.Chiwerengero cha michira ku China ndi yayikulu, ndipo ambiri aiwo sagwiritsidwa ntchito moyenera.Amasungidwa makamaka m'mayiwe a tailings kapena migodi yotayiramo, kuwononga chuma.Kuchulukana kwakukulu kwa michira sikungotenga malo ambiri, komanso kumawononga chilengedwe komanso kumakhudza thanzi la anthu.Chifukwa chake, kugwiritsidwa ntchito kwathunthu kwa tailings ndivuto lomwe likuyenera kuthetsedwa m'makampani amigodi aku China.HCMilling(Guilin Hongcheng), monga wopanga tailingsvertical roller mphero, idzayambitsa njira yokonzekera klinka ya simenti kuchokera ku michira.

Mchere waukulu mu sulphoaluminate simenti clinker ndi calcium sulphoaluminate ndi dicalcium silicate (C2S).Calcium, silika, aluminiyamu ndi sulfure zopangira ndizofunikira pokonzekera.Monga clinker ya simenti ya sulphoaluminate ili ndi zipangizo zosiyanasiyana komanso zofunikira zochepa za kalasi, zinyalala zolimba zingagwiritsidwe ntchito moyenera m'malo mwa zipangizo zina.Zigawo zazikulu zamakina a michira zikuphatikizapo SiO2, Fe2O3, Al2O3, CaF2, ndi zina zotero, komanso zochepa za W, Mo, Bi ndi zina.Chifukwa zigawo za mankhwala a tailings ndi ofanana ndi katundu wa silika zopangira ntchito pokonzekera sulphoaluminate simenti clinker, michira angagwiritsidwe ntchito m'malo mwa silika yaiwisi, amene osati kupulumutsa nthaka, komanso kuteteza chilengedwe.CaF2 mu michira ya tungsten ndi mineralizer yothandiza kwambiri, yomwe imatha kulimbikitsa mapangidwe a mchere osiyanasiyana mu clinker ndi kuchepetsa kutentha kwa sintering kwa clinker.Panthawi imodzimodziyo, clinker ya simenti imatha kuthetsa Ti mu titaniyamu gypsum ndi W, Mo, Bi ndi zinthu zina zofufuza mu tungsten tailings.Zinthu zina zimatha kulowa mumtambo wa crystal wa mchere.Chifukwa utali wozungulira wa zinthu zolowa ndi wosiyana ndi zinthu zoyambirira za lattice, magawo a lattice adzasintha, zomwe zimapangitsa kupotoza kwa lattice, Itha kusintha magwiridwe antchito a mchere ndikusintha mawonekedwe a clinker.

Njira yokonzekera klinka ya simenti kuchokera ku michira: gwiritsani ntchito michira kuti m'malo mwa siliceous zopangira zomwe zimagwiritsidwa ntchito popanga makina ochiritsira a simenti a sulphoaluminate, ndikusintha pang'ono zitsulo zotayidwa.Pambuyo akupera kwa fineness ena, kulamulira mapangidwe simenti clinker ndi C2S mchere kudzera alkalinity coefficient Cm ndi sulfure zotayidwa chiŵerengero P, ndi kukonzekera sulphoaluminate simenti clinker ndi zotayidwa phulusa, calcium carbide slag, titaniyamu gypsum ndi zosakaniza zina.Masitepewo ndi awa: tailings, phulusa la aluminiyamu, carbide slag ndi titaniyamu gypsum zimatsitsidwa mpaka ma meshes osachepera 200;Yesani chigawo chilichonse chopangira zinthu molingana ndi chiŵerengero cha zopangira, kusakaniza ndi kusonkhezera mofanana, kanikizani kusakaniza mu keke yoyesera ndi piritsi, ndikuumitsa kwa 10h ~ 12h pa 100 ℃ ~ 105 ℃ kwa standby;Keke yoyeserera yokonzedwa imayikidwa mu ng'anjo yotentha kwambiri, yotenthedwa mpaka 1260 ℃～1300 ℃, yosungidwa kwa 40～55min, ndi kuzimitsidwa kwa firiji kupeza tungsten michira sulphoaluminate simenti clinker.Pakati pawo, ntchito michira ofukulawodzigudubuza mphero akupera ndi waukulu ndondomeko sitepe.

HCMilling(Guilin Hongcheng) ndi Mlengi wa tailing ofukula wodzigudubuza mphero.ZathuMtengo wapatali wa magawo HLMvertical roller mpheroimatha kupera 80-600 mesh tailing powder, kupereka zida zabwino zothandizira njira yokonzekera klinka ya simenti kuchokera ku tailing.Ngati muli ndi zofunikira zogulira, chonde lemberani HCM kuti mudziwe zambiri za zida.
