  • Froth flotation of scheelite A review ScienceDirect

    2018-05-01· This explains why lead nitrate is able to activate scheelite (and wolframite) for its flotation with BHA. Han, Haisheng et al. showed that scheelite can be well collected by BHA and lead nitrate, in whichever order of addition, which is against the classical theory in flotation. They suggest using Pb-BHA complexes as a collector, with a ratio of lead ions to BHA of 1:2, 1:1 or 2:1, which

  • 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. There is two main tungsten ore

  • Significant Improvement in the Scheelite Heating Flotation

    Scheelite flotation has become a research hot spot in recent years because of the depletion of wolframite resources. Many methods, especially selective reagents [ 4 ], effective equipment [ 5,6 ], optimization of flowsheet [ 7 ] and recovery of associated scheelite from molybdenum ore [ 8 ], have been conducted to improve the utilization of scheelite.
