Tungsten Ore Rock Crusher-I

Tungsten ore low must be integrated mineral-rich concentrate to a smelting raw material. According to the type of tungsten ore dressing it can be divided into wolframite and scheelite mineral beneficiation two types. Present mining to wolframite quartz vein type, accounting for the amount of ore taken out more than 90%. Tungsten ore dressing methods mainly include hand-selected, HM election, re-election, flotation, magnetic separation and electrostatic separation methods such as. Wolframite in order to re-election dominated by flotation mainly scheelite. Most of our wolframite is easy to choose the type of ore, while the composition of scheelite ore complex, and mostly of refractory ore, coupled with low grade, so not a lot of development.
 

In addition, tungsten oxide minerals such as tungsten China currently not recycled. China’s tungsten ore dressing and processing plant started in 1952 a large-scale factory in Dajishan Tungsten establish 125t / d of gravity concentration plant, the late 50s, former Soviet Union Mechanobr Research and Design Institute for the downhill , West Mountain and hilly Miyama tungsten designed three large-scale tungsten ore processing plant put into operation one after another. 40 years in the production practice constantly sum up experience, and absorb foreign advanced technology dressing, through continuous improvement, so that beneficiation process is improving daily, processing technical and economic indicators have reached the world advanced level. Nanchang representative non-ferrous metals such as tungsten ore beneficiation company targets, despite nearly 10 years in the annual decline in ore grade, the tungsten recovery remained at 84% or more of the high concentrate grade (WO3) 66.7 % ~ 68.9% (up to 12 tungsten national standards: WO3 content is not less than 65%), ore grade (WO3) 0.25% ~ 0.27%, tailing grade (WO3) 0.036% ~ 0.046%.
