2016-12-1 Most of the world tungsten in extracted from scheelite (CaWO 4) and wolframite ((Fe,Mn)WO 4) , . Tungsten extraction is carried out generally by hydrometallurgical processes [5] , [6] . The tungsten content of concentrates and ores is converted to an intermediate compound e.g. sodium tungstate, tungstic acid or ammonium paratungstate, which is subsequently reduced to tungsten metal powder

2021-2-4 Electrodeposition of WC from Wolframite. A high-temperature, two-phase extraction technique has been developed for the recovery of tungstic oxide (WO3) from tungsten-bearing minerals. The technique consists of dissolving scheelite (CaWO4) or wolframite in a system of two immiscible liquids-sodium chloride and sodium silicate-at 1,080° C. Tungstic ...

2021-4-16 After the wolframite is separated by gravity separation, its crude concentrate often contains scheelite, cassiterite, molybdenite, bismuthite, pyrite, chalcopyrite, sphalerite and other minerals. Cassiterite and bismuthite are more enriched in high-grade coarse concentrate. These associated minerals are harmful impurities for tungsten concentrates, but there are also many useful minerals ...
