Imfucuza eqinile yezimboni yaseShayina ngokuyinhloko iyizinsalela, umlotha wempukane, i-gangue yamalahle, i-slag yokuncibilikisa, i-slag eshiswa ngamalahle kanye ne-desulfurization gypsum. Ukulungiswa kwezinto zokwakha ezivela ezimfucumfucwini eziqinile kuye kwadonsela ukunaka okwengeziwe. Abacwaningi bathuthukise izinga lokusetshenziswa okuphelele kwemfucuza eqinile embonini yezinto zokwakha ngokuthuthukisa nokucwaninga nokuthuthukiswa kwemishini nobuchwepheshe. Ngesikhathi esifanayo, amazwe ahlukahlukene akhiphe imithetho nemigomo esekelayo yokukhuthaza intshiseko yamabhizinisi yokusebenzisa imfucuza eqinile, ngaleyo ndlela kuthuthukiswe umthelela wemfucuza eqinile yezimboni emvelweni ngezinga elithile. Njengomkhiqizi wemishini yokugaya izinsimbi zensimbi, i-umshini wokugaya ojikelezayo oqondile we-iron tailings isetshenziswe kabanzi kuphrojekthi yokusebenzisa izinto zokwakha ezisebenzisa isihlabathi sensimbi. I-HCMilling (Guilin Hongcheng) izokwethula ubuchwepheshe bokulungiselela izinto zokwakha ezisebenzisa insimbi.

1. I-clinker yesimende ene-calcined

Ukuthunga insimbi kucebile ngesakhi sensimbi, esingathatha indawo yempuphu yensimbi njengezinto zokusetshenziswa zokukhiqiza i-cement clinker. Ukushisa i-cement clinker nge-limestone, isihlabathi se-quartz kanye ne-iron tailings njengezinto zokusetshenziswa kunganciphisa ngempumelelo izinga lokushisa le-calcination kanye nezindleko ze-cement, kodwa inani lokuxuba lilinganiselwe, futhi inani lokuxuba ngokweqile lizonciphisa kakhulu amandla esimende. Njengamanje, inani le-iron tailings elisetshenziselwa i-calcining i-cement clinker licishe libe yi-15%. Kuyaphuthuma ukuthuthukisa imishini emisha kanye nobuchwepheshe obusha ukuthuthukisa inani le-iron tailings nokuqinisekisa ikhwalithi yemikhiqizo yesimende.

2. Iqoqo likakhonkolo

Ukuqina okuphezulu kwe-iron tailings kuvela kakhulu esigabeni sangaphakathi se-quartz, lapho usayizi wezinhlayiya useduze nesihlabathi somfula semvelo kanye nesihlabathi esenziwe, futhi singaxutshwa sibe yi-concrete njenge-aggregate. I-concrete enamandla angu-28d angaba ngu-40MPa ingalungiswa ngokusebenzisa i-iron tailings enosayizi wezinhlayiya ezingaphansi kuka-1mm ukuze ithathe indawo yesihlabathi somfula semvelo njenge-aggregate encane. Ngokusekelwe ekuthuthukisweni kokuhlela okuhlanganisiwe, ukusetshenziswa okuhlanganisiwe kwe-iron tailings kanye nesihlabathi esenziwe ngomshini njenge-aggregate akugcini nje ngokuhlangabezana nezidingo ze-concrete yezinto zokwakha, kodwa futhi kunokuqina okungcono kune-iron tailings kanye nesihlabathi somfula semvelo, okusiza kakhulu ekulawuleni ikhwalithi ye-concrete. Ngokuphathelene nenqubo yokuzuza yamanje, ukuze kuthuthukiswe izinga lokubuyiselwa kwensimbi, izinhlayiya ze-iron tailings ziya ngokuya zicwebezela, okunzima ukuhlangabezana nezinga le-coarse aggregate futhi zisetshenziswe kukhonkrithi evamile.

3. Ukuhlanganiswa kwamaminerali aqinile

Izingxube zamaminerali zakhiwe kakhulu ngezinto ezi-amorphous siliceous, calcareous kanye ne-aluminium, ezidlala indima ebalulekile ekuthuthukiseni ukuqina, ukungangeni kwamanzi kanye nokuqina kwekhonkrithi. Zinganciphisa ukusetshenziswa kwekhonkrithi futhi zinciphise ukushisa kwamanzi ngesikhathi esisodwa. Ngakho-ke, kubalulekile ukuthola izingxube zamaminerali ezintsha zentuthuko eqhubekayo yemboni yekhonkrithi. Isigaba esiyinhloko samaminerali ezinsikeni zensimbi ngokuvamile yi-quartz, enomsebenzi omncane we-pozzolanic esimweni semvelo. Indlela yokuthuthukisa "umsebenzi we-pozzolanic" wezinsikeni zensimbi isibe yisihloko esiyinhloko sabacwaningi bamanje. Njengenye yezindlela ezisetshenziswa kakhulu zokusebenzisa izinsikeni zensimbi, ukugaya ngomshini kunganciphisa amandla okusebenza kwezinsikeni zensimbi futhi kukhiqize amaphutha amaningi e-lattice kanye nokuguqulwa kwepulasitiki. Ucwaningo lubonisa ukuthi ukugaya ngomshini kungakhuthaza umsebenzi we-pozzolanic wezigaba ezijwayelekile zamaminerali ezinsikeni zensimbi. Njengoba usayizi wezinhlayiya zamaminerali aqunyiwe ngomshini wehla, i-quartz ingasabela nge-Ca (OH) 2 kusimende ukuze ikhiqize i-amorphous hydrated calcium silicate gel kanye ne-ettringite crystal kanye neminye imikhiqizo ye-hydration. Ucwaningo lubonisa ukuthi uma ukugaya ngomshini kungaphezu kwemizuzu engama-40, i-engeli ebukhali ye-iron tailings iyancishiswa ngokusobala, izinhlayiya ezincane ziyavezwa, futhi ukufana kuyathuthuka kancane kancane. Kuhlelo lwe-anhydrite iron tailing calcium oxide, i-siliceous iron tailing yokugaya ngomshini ingaxutshwa no-30% ukulungiselela usimende ongu-32.5. Ngaphansi kwesimo sesilinganiso esiphansi se-water binder, i-fine iron tailings powder ingakhuthaza kakhulu ukumuncwa kokuqala kwe-composite cement paste, yenze isakhiwo se-pore se-mortar sibe sincane kakhulu, futhi ithuthukise amandla okuqala. Ukwanda kwendawo ethile ebusweni be-iron tailings akunamphumela ocacile ekuthuthukiseni inkomba yayo yomsebenzi; Ukushintsha kwezinga lokushisa lokwelapha kungakhuphula kakhulu inkomba yomsebenzi esigabeni sokuqala (7d), kodwa akunamthelela omkhulu kunkomba yomsebenzi esigabeni sokugcina (28d). Kuhlelo lwe-iron tailings slag composite, inkomba yomsebenzi ingathuthukiswa ngokuthuthukisa indlela yokugaya, ngaleyo ndlela kuthuthukiswe ukuqina kwekhonkrithi. Ukusetshenziswa okunengqondo kwe-ejenti yokunciphisa amanzi kungakhuphula okuqukethwe kwe-iron tailings kukhonkrithi evamile kusuka ku-30% kuya ku-40%. Ukugaya izinsimbi zensimbi kungathuthukisa ukusebenza kahle kokugaya ngomphumela waso, ngaleyo ndlela kuvuselele umsebenzi we-pozzolanic wezinsimbi zensimbi. Ngokwenza ngcono isilinganiso sezinsimbi zensimbi, i-slag, i-clinker kanye nezinto zokwakha i-gypsum ezihlanganisiwe, ukhonkolo osebenza kahle kakhulu ohlangabezana nezinga likazwelonke ungalungiswa.
