Wolframite mineral processing method mainly in gravity separation, and includes four parts: pre-selection, gravity separation, concentration and recovery.
The pre-concentration process is effectively applied in recovering wolframite from tungsten ore, due to its benefits of further upgrading tungsten ore and improving Study on pre-concentration efficiency of wolframite from tungsten ore … 719
Wolframite and cassiterite were separated by gravity concentration and in the following step wolframite was separated from cassiterite by electromagnetic separation. Chemical analysis of the obtained wolframite concentrate is given in Table 1.The apparatus and techniques used in the present w x investigation have been described elsewhere 17,18 .
Wolframite ore process most of the wolframite contained by big quartz vein or fine vein wolframite, rough embedded grain,easy to be separated.For the wolframite separation, utilize unit methods but mainly gravity concentration, divides into rough separation, gravity separation,.
Wolframite Wikipedia. Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.

A solid H 2 WO 4 layer forms on the surfaces of the wolframite particles and becomes denser with increasing H 2 SO 4 concentration, thus hindering the conversion.
