Tam sim no, muaj ntau pawg tseem ceeb ntawm cov txheej txheem rov ua dua tshiab rautungsten carbide.Ib qho yog cov txheej txheem kev kho kub kub, uas muaj xws li: txoj kev saltpeter melting, cua oxidation sintering txoj kev, oxygen calcination txoj kev, thiab lwm yam .;
lwm yam yog mechanical crushing txoj kev, uas muaj xws li: txias crushing txoj kev, kub crushing txoj kev, zinc melting txoj kev, thiab lwm yam .;Qhov thib peb yog txoj kev kho tshuaj, nrog rau cov txheej txheem hlau polyvalent ntsev, txoj kev chlorination, phosphoric acid leaching method, hydrochloric acid txoj kev kho, thiab lwm yam.;thib plaub yog electrochemical txoj kev, suav nrog
Muaj cov txheej txheem sib txawv siv cov alkali raws li dielectric, hydrochloric acid lossis sulfuric acid, thiab nitric acid li dielectric;kuj tseem muaj cov pa oxygen siab, ammonia lossis amine tov leaching txoj kev;carbonyl compound txoj kev thiab chav sublimation tungsten trioxide decomposition txoj kev, thiab lwm yam nyob rau hauv kev xyaum ntawmcemented carbiderecycling nyob rau hauv xyoo tas los no, vim hais tias yuav tsum nruj me ntsis rau kev tiv thaiv ib puag ncig, qee cov txheej txheem rov ua dua tau raug txiav tawm vim muaj kuab paug uas lawv ua.Tam sim no, txoj kev siv dav tshaj plaws yog kev siv tshuab crushing, zinc melting method thiab electrochemical electrolysis method.
