I-Molybdenum iwuhlobo lwe-metallic element, umbala womthofu, onokucwebezela kwe-metallic, okuyingxenye ye-hexagonal crystal system.Ingxenye ingu-4.7~4.8, ubulukhuni bungu-1 ~ 1.5, indawo encibilikayo ingu-795℃, uma ishiswa ibe ngu-400℃ 500℃, i-MoS2 kulula ukuyikhipha i-oxidize futhi ikhiqize ku-MoS3, kokubili i-nitric acid ne-aqua regia ingenza i-molybdenite (MoS2) incibilike. .I-Molybdenum inezinzuzo zamandla aphezulu, indawo ephezulu yokuncibilika, i-anti-corrosion, ukumelana nokuguga, njll. Ngakho-ke isetshenziswa kabanzi embonini.
I-China inomlando wengxenye yekhulu leminyaka ekugqokeni kwe-molybdenum ore, igebe phakathi kwenqubo yezobuchwepheshe yokugqoka i-molybdenum ore eShayina kanye namazwe angaphandle lincane futhi lincane.
Izimpahla zokugqoka ze-molybdenum ore zihlanganisa: isiphakeli esidlidlizayo, isigayo somhlathi, isigayo sebhola, umshini wokulinganisa ovunguzayo, umgqomo wokunyakazisa womkhiqizo wamaminerali, umshini wokuntanta, ukuqina, umshini wokomisa, njll.
Indlela yokugqoka i-Flotation iyindlela eyinhloko yokugqoka i-molybdenum ore e-China.Lapho ukhetha i-ore equkethe ikakhulukazi i-molybdenum ore kanye nethusi elincane, inqubo yezobuchwepheshe yengxenye yobuningi obukhethekile be-flotation iyamukelwa.Njengamanje, i-molybdenum igaywa kabusha isuka ku-copper molybdenum ore e-China, inqubo yobuchwepheshe esetshenziswa kaningi i-copper molybdenum bulk flotation, kunokucubungula ukuhlukaniswa phakathi kwethusi ne-molybdenum nokugqoka kahle kwe-molybdenum concentrate.
Inqubo yezobuchwepheshe yokugqoka i-molybdenum ore ihlanganisa: ukugqoka kwe-molybdenum ore, ukugqoka i-molybdenum ore yethusi, ukugqoka kwe-tungsten yethusi ye-molybdenum ore kanye nokugqoka kwe-molybdenum bismuth ore ukukhiqiza ukugxila kwe-molybdenum, njll.
Izindlela ezisetshenziswa njalo indlela ye-sodium sulphid kanye nendlela ye-sodium cyanide, ukuhlukanisa ithusi ne-molybdenum, ukhethe kahle i-molybdenum concentrate.Izikhathi zokugxila kwe-molybdenum ikakhulukazi zincike esilinganisweni sokuhlushwa se-molybdenum.Ngokuvamile, uma isilinganiso sokuhlushwa siphezulu, izikhathi zokukhethwa okuhle ziningi;uma isilinganiso sokuhlushwa esiphelele siphansi, izikhathi zokukhethwa okuhle zincane.Isibonelo, izinga le-ore eluhlaza ecutshungulwe i-Luanchuan molybdenum ore beneficiation plant lingaphezulu (0.2%～0.3%), isilinganiso sokuhlushwa ngu-133～155, izikhathi zayo zokukhetha ezinhle ezidizayinelwe .Ngokuqondene ne-Jindui Chengyi Beneficiation Plant, ibanga le-molybdenum lingu-0.1%, isilinganiso sokuhlushwa singu-430~520, izikhathi zokukhetha ezinhle zifinyelela ku-12.
Inqubo Yezobuchwepheshe Yokugqoka Kwe-Molybdenum Ore
1.I-molybdenum izocutshungulwa ukuchotshozwa okumahhadla nge-crusher yomhlathi, bese isigayigayi esicolile sichoboza insimbi ibe sezingeni elifanele lokuqina, izinto ezichotshoziwe zizolethwa emgqonyeni wesitoko ngekheshi.
2.Izinto ezisetshenziswayo zizolethwa emshinini wokugaya ibhola ngokufanayo ukuze zigaywe.
3.Izinto ezisetshenziswayo ze-ore emihle ngemva kokugaya zilethwa emshinini wokulinganisa okuvunguzayo ozogeza futhi ulinganise ingxube ye-ore ngokuncika esimisweni sokuthi ingxenye yezinhlayiya eziqinile ihlukile, izinga lokuncibilika lihlukile oketshezini.
4.Ngemva kokunyakaziswa ku-agitator, ihanjiswa emshinini wokuntanta ukuze isebenze.I-reagent flotation reagent izokwengezwa ngokuya ngezici ezihlukene zamaminerali, ibhamuza nezinhlayiyana ze-ore ziphahlazeka ngamandla, inhlanganisela yebhamuza nezinhlayiyana zensimbi zihlukene ngokwezibalo, okwenza insimbi edingekayo ihlukaniswe kwezinye izinto.Kuhle ekuzuzeni inhlayiyana ecolekileyo noma izinhlayiyana ezincane.
5.Sebenzisa i-concentrator esebenza kahle kakhulu ukuqeda amanzi aqukethwe kwinsimbi ecolekileyo ngemva kokuntanta, afinyelele izinga elilawulwayo lesizwe.
