Tungsten Ore Crusher

Tungsten is recovered from scheelite ore concentrates, or other tungsten concentrates which may, or may not contain scheelite in the form of sodium tungstate and in yields up to 99.5 percent or more by a process in which ground ore substantially below 200 mesh in particle size is first added to a 50 percent sodium hydroxide solution while being agitated to such an extent that the resulting mixture becomes a semi-solid as the temperature is raised above 80C. The semi-solid is then baked at 135 to 145C for about 1 to 2 hours, followed by adding sufficient water to the semi-solid to form a slurry having a sodium hydroxide concentration below 6 molar, separating the causticinsoluble sludge from the slurry and washing the sludge with a dilute sodium hydroxide solution to remove residual sodium tungstate.

Tungsten Ore Crusher processing

The other modifying agents required will depend on the gangue minerals to be depressed. Quebracho or tannin is used to depress the calcite, but an excess will also depress tungsten minerals. Sodium dichromate acidified with sulfuric acid has also been reported as a calcite depressant and copper silicate (sodium silicate and copper sulfate) has been reported as a depressant for fluorite. Figure 8 shows a tungsten flotation flowsheet. The most commonly used tungsten collectors are crude oleid acids or tall oils, or the more refined fatty acids or soaps.
