Tungsten Ore Extraction Processing Wolframite

For the single scheelite and wolframite with simple composition, the separation process is relatively simple. For the paragenetic ore of wolframite and scheelite, especially the paragenetic polymetallic ore of fine-grained wolframite and scheelite, tungsten is usually recovered by a mixed flotation process.

Examples of flotation reagent schemes for scheelite and

The PH value of the wolframite flotation with oleic acid is similar to that of scheelite, and sodium carbonate is used as the adjusting agent. The flotation of wolframite with phenylarsinic acid and phosphonic acid is carried out in acidic medium, and the regulator used is sulfuric acid or hydrochloric acid. Commonly used lead nitrate as activator.

The effect of sodium silicate depressant on the flotation

Quartz could be activated by metal ions dissolved from wolframite surfaces, making it difficult to separate wolframite from quartz. In this study, sodium silicate used as depressant was investigated in the flotation of fine wolframite.

Fatty acid flotation versus BHA flotation of tungsten

Feb 10, 2017· The similar flotability of scheelite, fluorite, and calcite resulted in the difficult separation by flotation. This work revealed the effect of water glass on the flotation of scheelite by FTIR and the wettability change of the usual cleavage plane, and proved that water glass inevitably influenced the flotation of tungsten minerals to a large extent in traditional fatty acid flotation process.
