Codsiga Molybdenum iyo caan ka qaadista sayniska

Molybdenum waa cunsur bir ah, astaan ​​curiye: Mo, Magaca Ingiriisiga: molybdenum, atomka nambarkiisa 42, waa biraha VIB. Cufnaanta molybdenum waa 10.2 g / cm 3, barta dhalaalaysa waa 2610 ℃ halka kuleylka waa 5560 ℃. Molybdenum waa nooc ka mid ah sillar bir cad, adag oo adag, oo leh barta dhalaalida sare iyo kuleylka kuleylka. Kama falceliso hawo heerkulka qolka. Sida cunsur ku-meel-gaadh ah, way fududahay in la beddelo xaaladdeeda oksidation, iyo midabka molybdenum ion ayaa isbeddeli doona isbeddelka xaaladda oksaydhka. Molybdenum waa cunsur muhiim u ah jirka, xoolaha iyo dhirta aadanaha, taasoo door muhiim ah ka qaata koritaanka, horumarka iyo dhaxalka dadka, xayawaanka iyo dhirta. Celceliska waxa ku jira molybdenum ee qolofta dhulka waa 0,00011%. Kaydka kaydka molybdenum ee adduunku waa ilaa 11 milyan oo tan, keydka la xaqiijiyayna waa illaa 19.4 milyan oo tan. 

Kheyraadka Molybdenum ee adduunka ayaa inta badan ku urursan cirifka bari ee Baasifiga, taas oo ah, laga bilaabo Alaska iyo British Columbia oo loo maro Mareykanka iyo Mexico ilaa Andes, Chile. Xadka ugu caansan waa buuraha Cordillera ee Ameerika. Waxaa jira tiro aad u fara badan oo ah molybdenum dhigaal ah iyo keydka naxaas ah ee buuraha ku jira, sida clemesk iyo Henderson porphyry molybdenum oo ku yaal Mareykanka, elteniente iyo chuki oo ku yaal Chile Meelaha loo yaqaan "borofry copper molybdenum" ee Kamata, El Salvador iyo pispidaka ee Kanada, andako porphyry molybdenum dhiga Canada iyo hailanwali porphyry copper molybdenum dhiga Kanada, iwm. Shiinaha sidoo kale qani ayuu ku yahay ilaha molybdenum, iyadoo gobolada Henan, Shaanxi iyo Jilin ay gaarayaan 56.5% wadarta guud ee hantida molybdenum ee Shiinaha.

Shiinaha waa mid ka mid ah dalalka leh ilaha molybdenum ee adduunka. Marka loo eego xogta ay soo saartay Wasaaradda dhulka iyo kheyraadka, dhammaadka sanadkii 2013, keydka Molybdenum ee Shiinaha wuxuu ahaa 26.202 milyan oo tan (macdan ka kooban). Sanadkii 2014, keydka Molybdenum ee Shiinaha wuxuu kordhay 1.066 milyan oo tan (maadada birta ah), sidaa darteed illaa 2014, keydka Molybdenum ee Shiinaha wuxuu gaaray 27.268 milyan oo tan (macdan bir ah). Intaa waxaa dheer, tan iyo sanadkii 2011, Shiinaha waxay soo saartay seddex macdan oo molybdenum ah oo qaadi kara 2 milyan oo tan, oo ay ku jiraan shapinggou ee Gobolka Anhui. Maaddaama ay tahay waddanka ugu weyn ee kheyraadka molybdenum ee adduunka, saldhigga kheyraadka Shiinaha waa mid xasilloon.
