Ekujuleni kwemayini, lapho isihlabathi samaminerali sigijima epayipini ngesivinini esikhulu, amapayipi ensimbi ajwayelekile avame ukugqokwa ngaphansi kwesigamu sonyaka. Ukulimala okuvamile kwale "mithambo yegazi yensimbi" akubangeli nje ukuchithwa kwezinsiza, kodwa futhi kungase kuholele ezingozini zokukhiqiza. Namuhla, uhlobo olusha lwempahla luhlinzeka ngokuvikelwa okuguquguqukayo kwezinhlelo zokuhamba zezimayini -i-silicon carbide ceramicszisebenza “njengesihlangu sezimboni” ukuze ziqaphe ngokuqinile umzila wokuphepha wezokuthutha zasezimayini.
1. Beka izikhali zobumba epayipini
Ukugqoka ungqimba oluvikelayo lwe-silicon carbide ceramic odongeni lwangaphakathi lwepayipi lensimbi elihambisa isihlabathi samaminerali kufana nokubeka amavesti angangenwa izinhlamvu epayipini. Ukuqina kwale Ceramic kungokwesibili ngemva kwedayimane, futhi ukumelana kwayo nokugqoka kukudlula kude okwensimbi. Lapho izinhlayiya zensimbi ebukhali ziqhubeka nokuba nomthelela ngaphakathi kwepayipi, ungqimba lwe-ceramic luhlala lugcina indawo ebushelelezi futhi entsha, lwandisa kakhulu impilo yesevisi yamapayipi ensimbi evamile.
2. Yenza ukugeleza kwe-slurry kube bushelelezi
Endaweni yokuthutha i-tailings, udaka oluqukethe amakhemikhali lufana "nomfula ogqwala", futhi imigodi yokuguguleka emise okwekhekheba lezinyosi izovela ngokushesha odongeni lwangaphakathi lwamapayipi ensimbi ajwayelekile. Isakhiwo esiminyene se-silicon carbide ceramics sifana "nesembozo esingenawo amanzi", esingagcini nje ukumelana nokuguguleka kwe-asidi ne-alkali, kodwa indawo yayo ebushelelezi nayo ingavimbela ukubopha kwe-mineral powder. Ngemuva kokuthi amakhasimende esebenzise umkhiqizo wethu, izingozi zokuvinjwa ziye zehla kakhulu futhi ukusebenza kahle kokumpompa kuye kwaba ngcono kancane kancane.
3. Ingcweti yokuqina ezindaweni ezinomswakama
Ipayipi lamanzi lemayini yamalahle licwiliswe emanzini angcolile aqukethe isibabule isikhathi eside, njengensimbi ecwiliswe oketshezini olubolayo isikhathi eside. Izakhiwo zokulwa nokugqwala kwe-silicon carbide ceramics zibenza babonise ukuqina okumangalisayo ezindaweni ezinomswakama. Lesi sici sinciphisa kakhulu izindleko zokulungisa, hhayi nje ukunciphisa izindleko zokulungiswa kwemishini, kodwa futhi sinciphisa ukulahlekelwa okubangelwa ukuphelelwa yisikhathi ngenxa yokunakekelwa kwemishini.
Isiphetho:
Ekuphishekeleni intuthuko esimeme namuhla, i-silicon carbide ceramics ayinciphisi kuphela izindleko futhi yandise ukusebenza kahle kwamabhizinisi, kodwa futhi inciphisa ukusetshenziswa kwezinsiza ngokwandisa impilo yemishini. Le nto yokucabanga 'isebenzisa amandla ezobuchwepheshe ukuvikela ukukhiqizwa kwezimayini kanye nokufaka amandla amasha aluhlaza embonini esindayo evamile. Ngokuzayo lapho ubona udaka olugijima emayini, mhlawumbe ungacabanga ukuthi phakathi kwala mapayipi ensimbi, kunongqimba “lwesivikelo sezimboni” buthule oluqapha ukugeleza kwegazi lezimboni.
