for tungsten ores, high density is their most important property. In addition, wolframite is a paramagnetic mineral [1]. Wolframite frigidity would cause it to be broken down in crushing stage, which produces thin flakes and ultrafine particles [4]. The main processes in tungsten concentrate production from its ores are gravity separation
Industrial practice has shown that a tungsten recovery higher than 98% for sheelite concentrate and 99% for scheelitewolframite mixed concentrate is obtained, under the conditions of NaOH/WO 3 mole ratio of 3648, 160170 °C, and it is suitable to treat almost any sort of tungsten ore concentrates, including low grade complex.

Key: Obtain the tungsten concentrate with high recovery and high quality. Tungsten Extraction Process: √ In coarse grinding stage, Xinhai adds xanthophyll collector to float various sulfides first; √ In the gravity separation stage, Xinhai adopts the shaking table to get some or all qualified tungsten concentrate. √ For the tailings after the gravity separation stage, Xinhai floats the ...
The kinetics and mechanism of natural wolframite interactions with sodium carbonate during air heating were studied. Xray phase and Xray microanalysis were used to establish that the initial monocrystalline wolframite consists of Fe Mn WO 4 and Fe Mn WO 4 . Differential thermal analysis showed that the interaction of wolframite with sodium carbonate begins .

shows that the deposit has the potential to become one of the lowest cost tungsten producers. Wolframite mineralisation is hosted in a 25 Mt pipelike breccia body drilled to 130m below surface outcropping on the side of a hill. The breccia has also been intersected near and on surface by adits from previous mining during the mid 1900`s. The mineralised zone within the .
