Molybdenum Recycling Methods

Molybdenum recycling txoj kev Tam sim no, molybdenum pov tseg txoj kev rov ua dua tshiab kuj muaj ntau, tab sis feem ntau yog raws li txoj kev tua hluav taws, ntxiv los ntawm cov txheej txheem ntub dej, cov txheej txheem ntau yog raws li hauv qab no:

Sublimation txoj kev: Qhov no yog ib txoj kev raws li cov hlau molybdenum tuaj yeem oxidized rau hauv molybdenum trioxide ntawm qhov kub thiab txias thiab sublimation thiab ntes thiab rov qab, tus nqi rov qab mus txog 98%. Txoj kev no tsuas yog siv rau kev rov ua dua ntawm cov khib nyiab molybdenum hmoov, molybdenum strips, molybdenum flakes, molybdenum hlau, molybdenum rhenium alloy, thiab high-speed steel sib tsoo khib nyiab.

Zinc melting txoj kev: txoj kev no tsuas yog los ntawm cua sov, distillation, roasting rov qab ntawm cemented carbide thiab superalloy pov tseg nyob rau hauv cov ntsiab lus alloy, xws li cobalt (rov qab tus nqi ntawm 97%), molybdenum (rov qab tus nqi ntawm 96.2%), tungsten (rov qab. tus nqi ntawm 98.4%).

Oxidation roasting thiab acid leaching txoj kev: Txoj kev no tsuas yog siv rau kev rov ua dua ntawm molybdenum-muaj catalysts, thiab cov nqi rov qab ntawm cobalt thiab molybdenum yog 97% thiab 95% feem.

Sodium carbonate roasting thiab leaching txoj kev: txoj kev no tseem yog tsuas yog siv rau kev rov qab los ntawm molybdenum-muaj catalysts siv, tab sis tsuas yog rau kev rov qab los ntawm cobalt thiab npib tsib xee, thiab lawv cov leaching tus nqi siab tshaj 90%.

Alkali leaching txoj kev: Nws yog tsuas yog siv rau kev tsim kho thiab rov qab los ntawm molybdenum thiab nickel-muaj cov khib nyiab catalysts, thiab cov leaching tus nqi ntawm molybdenum, txhuas thiab npib tsib xee yog 96.9%, 86.7% thiab 90.1% feem.
