Ingabe ukhathazekile ngamanzi amaningi kakhulu lapho kugeleza khona kanye nezinto eziqinile lapho kugeleza khona? Ingabe uhlose ukwenza ngcono ukusebenza kwe-thickener ngokususa ukulinganiswa kobuningi obuphindaphindwayo kanye namaphutha abantu? Abasebenzisi abaningi bokugcina babhekene nezinkinga ezifanayo embonini yokucubungula amaminerali ukuze bonge amanzi futhi baqoqe izinto ezibalulekile zokucubungula. Imitha yobuningi besikhathi sangempela isebenza kahle ekufinyeleleni le migomo.
Isihloko esilandelayo sigxile ekuchazeni izinhloso nezinzuzo zokulawula ubuningi ezindaweni ezahlukene zamathangi okujiya. Ake siqale ngesingeniso esifushane senqubo yokujiya, silandelwe yizizathu ezinhlanu zokulinganisa ubuningi enkambisweni yokuhlukanisa.
Uyini Umsebenzi Wokujiya?
Inqubo yokujiya ihilela ukuhlukaniswa kwengxube eqinile-ewuketshezi ibe ukugeleza okujiyile kanye nokuchichima okucacile ngokujwayelekile. Eyokuqala yakhiwa izinhlayiya eziqinile kanti eyesibili ayifaki ukungcola ngangokunokwenzeka. Inqubo yokuhlukaniswa iwumphumela wamandla adonsela phansi. Zonke izinhlayiya ngobukhulu obuhlukene kanye nobuningi zakha izendlalelo ezahlukene ethangini.
Izinqubo zokujiya zenzeka ethangini lokuthungwa kwezimbiwa ekucutshungulweni kwamaminerali ukuze kuhlukaniswe ama-concentrate kanye nama-tailings.
Amaphuzu Okulinganisa Adingekayo Ekuqineni
Amamitha okuminyana koketshezi ku-inthanethiKudingeka ukuze kwenziwe ngcono ukusebenza kwezithina. Isibonelo, izindawo zokufaka zifaka phakathi ukudla, ukugeleza kwamanzi, ukugcwala kanye nengaphakathi lethangi lesithina. Ezimweni ezingenhla, lezi zinzwa zingathathwa njengeimitha yobuningi be-slurrynomaimitha yobuningi bodakaZiyasiza futhi ekuthuthukiseni ukulawulwa okuzenzakalelayo kwama-drive, amaphampu kanye nokulinganisa kahle ama-flocculant.
Izizathu Zokulinganisa Ubuningi
Izizathu zokulinganisa ubuningi zingase zihluke ngasinye ngasinye. Lezi zimo ezinhlanu ezilandelayo ziqokomisa ukubaluleka kokuqapha ubuningi ukuze kwenziwe ngcono izimboni.
Ukubuyiswa Kwamanzi No. 1
Amanzi abhekwa njengenye yezimpahla ezibaluleke kakhulu embonini yezimayini kanye neyezimbiwa. Ngakho-ke, ukubuyiswa kwamanzi noma ukusetshenziswa kabusha kwamanzi kusindisa kakhulu izindleko zokujiya. Ukukhula okuncane okungu-1-2% kobuningi bokugeleza kwamanzi kusho inani elikhulu lamanzi adingekayo ukuze kusetshenziswe ukufakwa. Ukwanda kobuningi kusebenza kahle ekuqinisekiseni ukuqina emadamini asemuva, okungase kubhidlike uma kukhona uketshezi oluningi olupompelwa emadamini.
Ukubuyiswa Kwamaminerali Okwesibili
Kuma-thickener agxilile, ukudla ngokuvamile kuvela ku-flotation circuit. Ukuntanta kuhilela ukuhlukanisa izinhlayiya ngokusebenzisa amandla adonsela phansi. Ngamanye amazwi, lezo ezinamabhamuza omoya anamathele ziyaphakama ziye phezulu bese zisuswa, kanti ezinye zihlala esigabeni soketshezi. Uma le nqubo yenzeka ku-thickener yomkhiqizo, i-foam ingathwala izinto eziqinile ziye ekuchichimeni.
Lezi zinto eziqinile ziyigugu futhi, uma zingatholakali, zinganciphisa izinga lokubuyiselwa kwensimbi egxilile. Ngaphezu kwalokho, izinto eziqinile ezichichimayo zingaholela ezindleleni eziphezulu zokuvuselela, ukulimala kwamaphampu namavalvu, kanye nezindleko zokulungisa ezengeziwe, njengokuhlanza amathangi amanzi lapho izinto eziqinile ziqongelela khona.
Cishe ama-90% ezinto eziqinile ezilahlekile ekuchichimeni ekugcineni zitholakala ezigabeni zakamuva zenqubo (isb., ematangini nasemadamini). Kodwa-ke, ama-10% asele, amelela inani elikhulu kwezomnotho, alahleka unomphela. Ngakho-ke ukunciphisa ukulahlekelwa kwezinto eziqinile ekuchichimeni kufanele kube yinto eza kuqala. Ukutshala imali kubuchwepheshe bokulawula izinqubo kungathuthukisa amazinga okubuyisa imali futhi kulethe imbuyiselo esheshayo ekutshalweni kwemali.
Ukusetshenziswa kweLonnmeteramamitha okuminyanafuthiamamitha okugelezaekugelezeni okungaphansi kwenza kube lula ukuqapha ukusebenza kwe-thickener. Ukutholwa kwesikhathi sangempela kwezinto eziqinile ekuchichimeni kungenzeka futhi ngamamitha okuminyana noma amamitha aqinile. Izimpawu zamathuluzi angu-4-20mA zingafakwa ohlelweni lokulawula ukuze kwenziwe ngcono inqubo ngqo.
3 Ukusetshenziswa Kahle Kwe-Flocculant
Ama-Flocculants asebenza ekuthuthukiseni ukusebenza kahle kwe-sedimentation, okungukuthi amakhemikhali asiza izinhlayiya eziketshezini ukuthi zihlangane ndawonye. Umthamo wama-flocculants ubheka ukulawula izindleko phezu kwe-reagent kanye nokusebenza kahle. Imitha yobuningi ivumela ukulawula ubuningi obuqondile nobuthembekile bokuphakelwa kokuqina. Umgomo uwukufinyelela iphesenti eliphezulu kakhulu lezinto eziqinile ngesisindo ku-slurry yokuphakelwa ngenkathi kusavumela ukuhlangana kwezinhlayiya okukhululekile. Uma ubuningi be-slurry yokuphakelwa budlula okuhlosiwe, uphuzo olwengeziwe lwenqubo kumele lungezwe, futhi kungadingeka amandla amaningi okuxuba ukuqinisekisa ukuxubana okwanele komthombo wokuphakelwa.
Ukulinganisa ubuningi be-feed slurry ngesikhathi sangempela kusetshenziswa imitha yobuningi eqondile kubalulekile ekulawuleni inqubo. Lokhu kuqinisekisa ukusetshenziswa kahle kwe-flocculant futhi kuthuthukisa inqubo yokuxuba, kugcina i-thickener isebenza ngaphakathi kobubanzi bayo obuqondiwe.
4 Ukutholwa Ngokushesha Kwezinkinga Zokukhukhuleka Kwegazi
Abaqhubi balwela ukugcina izimo ezizinzile kuma-thickeners, befinyelela ukuchichima okucacile okunezinhlayiya ezincane kanye nokuchichima okuxinene okunezinhlayiya ezincane. Kodwa-ke, izimo zenqubo zingashintsha ngokuhamba kwesikhathi, okungase kuholele ekumisweni okungekuhle, ukwehla kobuningi bokuchichima, kanye nokuchichima okuphezulu. Lezi zinkinga zingabangelwa izinkinga zokukhukhuleka, umoya noma igwebu ethangini, noma ukugcwala okuphezulu kakhulu kwezinhlayiya ekudleni.
Ukufakwa kwezinsimbi kanye nokwenza izinto ngokuzenzakalela kungasiza opharetha ukuthi balondoloze ukulawula ngokuthola izinkinga ezinjalo ngesikhathi sangempela. Ngaphandle kokulinganisa okuqondile, ukusetshenziswa kwezinsimbi okusekelwe ethangini njenge-ultrasonic bed level probes kunganikeza ukuqonda okubalulekile. Lawa ma-probe “okudonsa” ahamba phezulu naphansi ngaphakathi ethangini, ehlola amazinga odaka, izindawo zokuhlala, kanye nokucaca kokugcwala. Ukulinganiswa kwezinga lombhede kuwusizo kakhulu kumasu okulawula ukugeleza kwamanzi, okuqinisekisa ukusebenza okulinganayo.
Imitha Yobuningi Be-Slurry (SDM)
I-Slurry Density Meter (SDM) iyindlela engcono kakhulu yokulinganisa ubuningi benuzi ngokwemvelo esikhundleni samamitha obuningi benuzi endabuko. Ithole ukuthandwa ngokushesha, inezindawo eziningi emhlabeni jikelele. I-SDM inikeza izilinganiso zobuningi ezinembile nezithembekile, okwenza kube yisisombululo esifanele sezitshalo zanamuhla zokucubungula amaminerali.
Ukulinganisa ubuningi kudlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kwe-thickener futhi kusebenza njengesibonakaliso esibalulekile sokusebenza sokulawula inqubo. Ngokwamukela ubuchwepheshe bokulinganisa obuthuthukisiwe namasu okulawula inqubo, opharetha bangenza ngcono ukusebenza kwe-thickener, bathuthukise amazinga okubuyisa, futhi banciphise izindleko zokusebenza.
