- Kugwirizana kwa zinthu:Zimathandizira kuti slurry ipangidwe bwino komanso kuti zinthu zolimba zisamayimitsidwe, zomwe ndizofunikira kwambiri pakudya mofanana m'njira zosefera slurry komanso magawo otsatira a flotation.
- Kukonza njira:Imathandizira kugwira ntchito mokhazikika komanso imathandizira magwiridwe antchito apansi pamadzi, kupewa kutsekeka kwa mapaipi ndi kukwera kwa madzi komwe kungasokoneze malangizo oyendetsera dosing ya reagent kapena kuyenda kwa njira.
Chitsanzo: Mu malo oyandama a tungsten-molybdenum olemera kwambiri, malo osungiramo thanki yosungiramo zinthu omwe amapangidwa ndi kusunthika koyenera komanso malo osungiramo zinthu zamoyo amathandiza kuti zomera zipitirire bwino komanso kuti zikhale bwino, makamaka panthawi yosinthasintha kwa chitsulo kapena kusintha kwa ntchito.
Kodi kuchuluka kwa mineralization kumakhudza bwanji mphamvu ya flotation ya molybdenum?
Kuchuluka kwa mchere m'nthaka—komwe kumadziwika ndi kuchuluka kwa ma ayoni osungunuka—kumakhudza kwambiri thovu la molybdenumnjira zoyandama.
- Kusakhazikika kwa thovu:Mphamvu yowonjezera ya ayoni imatha kusokoneza thovu loyandama, kuchepetsa kusankha kwa kuyandama ndi kubwezeretsa mphamvu.
- Kugwiritsa ntchito bwino ma reagent:Ma reagent ambiri amafunika kuti athetse mavuto ambiri a yankho, zomwe zimawonjezera ndalama zogwirira ntchito komanso chiopsezo cha zotsatira zosafunikira za mankhwala.
- Kuvuta kwa kulekanitsa:Kusankha kumachepa pamene ma ayoni a mkuwa, calcium, kapena sulfate osungunuka amasokoneza kuyandama kwa molybdenite ndi scheelite. Izi zimapangitsa kuti kulekanitsa kukhale kovuta, zomwe zimafuna kusintha nthawi zonse mlingo wa reagent wopangira mchere.
- Kuyang'anira njira:Kuchuluka kwa mchere m'nthaka kumafuna kuwongolera ndi kuyang'anira mwamphamvu—monga pH yopitilira kapena kuyeza ma conductivity—kuti pakhalebe bwino kayendedwe ka flotation ndikuwongolera bwino reagent dosing.
Chitsanzo: Zomera zomwe zimagwiritsa ntchito matope okhala ndi mchere wambiri nthawi zambiri zimagwiritsa ntchito ma Lonnmeter inline analyzers kuti zisinthe zokha kuchuluka kwa chakudya chosonkhanitsa ndi chochepetsa kupsinjika, kuchepetsa kusakhazikika kwa thovu ndikuthandizira njira zowongolera njira zoyandama.
