Beneficiation of tungsten-germanium-gold deposit in Xiangxi gold deposit, Hunan
The ore dressing process of the mine is shown in the figure below.
The ore of this mine belongs to the medium-low temperature hydrothermal tungsten- strontium - gold deposit. The main minerals are scheelite , stibnite and natural gold. Followed wolframite, pyrite, sphalerite, galena, arsenopyrite and other gangue minerals as quartz, calcite followed, apatite, dolomite, uneven thickness state was useful minerals disseminated In the veins.
In the process flow, the flotation is used for recovery, and both gold and tungsten are recovered by re-election plus flotation. The flotation conditions and indicators are listed in the table below.
