Molybdenum ndi mtundu wazitsulo zachitsulo, mtundu wa leaden, wokhala ndi zitsulo zonyezimira, za hexagonal crystal system.Gawo ndi 4.7 ~ 4.8, kuuma ndi 1 ~ 1.5, malo osungunuka ndi 795 ℃, pamene akutenthedwa kufika 400 ~ 500 ℃, MoS2 ndi yosavuta oxidize ndi kupanga mu MoS3, nitric acid ndi aqua regia akhoza kupanga molybdenite (MoS2) kupasuka. .Molybdenum ali ndi ubwino wokhala ndi mphamvu zambiri, malo osungunuka kwambiri, odana ndi dzimbiri, osavala, ndi zina zotero. Choncho amagwiritsidwa ntchito kwambiri m'makampani.
China ili ndi mbiri yazaka makumi asanu ndi limodzi pakuvala kwa molybdenum ore, kusiyana pakati paukadaulo wa mavalidwe a miyala ya molybdenum ku China ndi mayiko akunja ndi ang'onoang'ono komanso ang'onoang'ono.
Zida zobvala za Molybdenum ore zimaphatikizapo: chodyetsa chogwedeza, chophwanyira nsagwada, mphero ya mpira, makina ozungulira ozungulira, mbiya yopangira mchere, makina oyandama, makulidwe, makina owumitsa, ndi zina zambiri.
Njira yovala yoyandama ndiyo njira yayikulu yopangira molybdenum ore kuvala ku China.Posankha miyala yamtengo wapatali yomwe imakhala ndi molybdenum ore ndi mkuwa pang'ono, njira yaukadaulo ya gawo lalikulu loyandama limatengera.Pakali pano, molybdenum amapangidwanso kuchokera ku mkuwa wa molybdenum ore ku China, njira zamakono zomwe zimagwiritsidwa ntchito mobwerezabwereza ndi copper molybdenum bulk flotation, kusiyana ndi kukonza kupatukana pakati pa mkuwa ndi molybdenum ndi kuvala bwino kwa molybdenum concentrate.
Njira zamakono zopangira ma molybdenum ore kuvala kumaphatikizapo: kuvala kwa molybdenum ore, kuvala kwa mkuwa wa molybdenum ore, kuvala kwa tungsten mkuwa wa molybdenum ore ndi kuvala kwa molybdenum bismuth ore kupanga molybdenum concentrate, ndi zina zotero.
Njira zomwe zimagwiritsidwa ntchito pafupipafupi ndi njira ya sodium sulphid ndi njira ya sodium cyanide, kupatutsa mkuwa ndi molybdenum, kusankha bwino molybdenum.Nthawi zokhazikika za molybdenum zimatengera kuchuluka kwa ndende ya molybdenum.Nthawi zambiri, ngati chiŵerengero chonse cha ndende chili chokwera, ndiye kuti nthawi yosankha bwino ndi yochulukirapo;ngati chiŵerengero chonse cha ndende chili chochepa, nthawi zosankhidwa bwino ndizochepa.Mwachitsanzo, kalasi ya ore yaiwisi kukonzedwa ndi Luanchuan molybdenum ore Beneficiation chomera ndi apamwamba (0.2% ~0.3%), ndende chiŵerengero ndi 133 ~ 155, izo original cholinga kusankha zabwino nthawi.Ponena za Jindui Chengyi Beneficiation Plant, kalasi ya molybdenum ndi 0.1%, chiŵerengero cha ndende ndi 430 ~ 520, nthawi zosankhidwa bwino zimafika 12.
Njira Yaukadaulo Yamavalidwe a Molybdenum Ore
1.The molybdenum idzakonzedwa kuti iphwanyidwe ndi nsagwada, kenako chophwanya nsagwada yabwino imaphwanya miyalayo kuti ikhale yolimba, zinthu zophwanyidwazo zimaperekedwa mu nkhokwe ndi elevator.
2.Zinthu zimaperekedwa ku mphero ya mpira mofanana kuti akupera.
3.Zinthu zabwino za ore pambuyo pogaya zimaperekedwa ku makina opangira ma spiral omwe amatsuka ndikuyika kusakaniza kwa ore kutengera mfundo yakuti gawo la tinthu tating'onoting'ono ndi tosiyana, kuchuluka kwa sedimentation kumakhala kosiyana ndi madzi.
4.Atatha kugwedezeka mu agitator, amaperekedwa ku makina oyandama kuti agwire ntchito yoyandama.Mtolankhani flotation reagent zidzawonjezedwa malinga ndi makhalidwe osiyana mchere, kuwira ndi ore tinthu ngozi dynamically, kuphatikiza kuwira ndi miyala tinthu osiyana statically, zomwe zimapangitsa ore anafunika kulekana ndi zinthu zina.Ndi bwino kupindula ndi tinthu tating'onoting'ono kapena tinthu tating'onoting'ono.
5. Gwiritsani ntchito cholumikizira champhamvu kwambiri kuti muchotse madzi omwe ali mu miyala yabwino akayandama, kufikira momwe dziko limayendera.
